00:00:00.200 --> 00:00:04.160
Welcome to Huberman Lab Essentials, where we revisit past episodes
2
00:00:04.400 --> 00:00:07.639
for the most potent and actionable science based tools for
3
00:00:07.759 --> 00:00:12.800
mental health, physical health, and performance. I'm Andrew Huberman, and
4
00:00:12.839 --> 00:00:16.559
I'm a professor of neurobiology and ophthalmology at Stanford School
5
00:00:16.559 --> 00:00:20.280
of Medicine, and now for my discussion with doctor Kyle Gillette.
6
00:00:20.519 --> 00:00:23.239
Doctor Gillette, great to have you back, Great to be back.
7
00:00:23.239 --> 00:00:23.559
Thank you.
8
00:00:24.079 --> 00:00:26.879
I'd like to begin with a question about what all
9
00:00:26.960 --> 00:00:30.440
males ought to do in order to optimize their hormones.
10
00:00:30.760 --> 00:00:33.200
What should they be doing, what should they avoid doing?
11
00:00:33.439 --> 00:00:35.719
If the goal is to have a long arc of
12
00:00:35.799 --> 00:00:38.600
healthy hormone optimization throughout the lifespan.
13
00:00:38.560 --> 00:00:41.960
There's many things that you should do. An analogy that
14
00:00:42.039 --> 00:00:44.640
I often make is when there's a brand new car
15
00:00:44.679 --> 00:00:47.000
that comes off the assembly line, you do a full
16
00:00:47.079 --> 00:00:49.560
scope of diagnostic workup, hook it up to the computer.
17
00:00:50.119 --> 00:00:51.439
And I think we should do the same thing with
18
00:00:51.520 --> 00:00:55.079
humans as well. Dear, in puberty, you know, obviously you're
19
00:00:55.119 --> 00:00:59.240
a functioning human, but I would say there's still development,
20
00:00:59.479 --> 00:01:02.479
and I think the human always develops. I don't think
21
00:01:02.479 --> 00:01:05.879
development ever ends, but you want to monitor that progress
22
00:01:05.920 --> 00:01:08.519
across a person's lifespan.
23
00:01:09.040 --> 00:01:11.280
What do you think are the key things to look
24
00:01:11.319 --> 00:01:13.920
for in blood work? I mean, testosterone is always the
25
00:01:14.040 --> 00:01:16.640
topic that comes up in the context of male hormone optimization,
26
00:01:16.680 --> 00:01:18.200
but certainly there are a lot of other hormones that
27
00:01:18.200 --> 00:01:19.120
are important as well.
28
00:01:19.840 --> 00:01:22.560
And with testosterone, you want to get either testosterone in
29
00:01:22.560 --> 00:01:25.000
an SHBG or a free testosterone.
30
00:01:25.000 --> 00:01:27.319
Could you define SHBG for our listeners please.
31
00:01:27.400 --> 00:01:30.280
It is sex hormone binding globulin. It is the protein
32
00:01:30.359 --> 00:01:33.879
that binds up all androgens and estrogen to the body.
33
00:01:34.239 --> 00:01:38.439
So the stronger the androgen, the stronger it binds. During puberty,
34
00:01:39.200 --> 00:01:43.879
strong androgens, especially DHT, which is the strongest bioidentical androgen,
35
00:01:44.599 --> 00:01:49.719
has a huge role a prominent role in secondary sexual characteristics.
36
00:01:50.239 --> 00:01:53.359
And if your SHBG is very high, then your DHT
37
00:01:53.599 --> 00:01:56.719
can run higher because it's not metabolized, but there's not
38
00:01:56.799 --> 00:01:59.359
quite as much free DHD, So you want to balance
39
00:01:59.400 --> 00:02:04.719
between a high enough free DHD and a high enough TOTALDHD.
40
00:02:05.000 --> 00:02:08.240
So, assuming that there's no major intervention, how often do
41
00:02:08.240 --> 00:02:10.639
you recommend that people get their blood work.
42
00:02:10.439 --> 00:02:15.000
Done using shared decision making with their physician. Usually a
43
00:02:15.000 --> 00:02:16.960
good follow up is about six months.
44
00:02:16.719 --> 00:02:19.360
So on a daily basis, maybe you could just take
45
00:02:19.400 --> 00:02:22.560
us through the arc of a day and push out
46
00:02:22.560 --> 00:02:24.479
some of the protocols that you use or the things
47
00:02:24.520 --> 00:02:26.360
that you'd like to see your male patients use in
48
00:02:26.479 --> 00:02:29.479
order to try and optimize their hormone status.
49
00:02:29.599 --> 00:02:31.919
I'll briefly touch on some of the lifestyle pillars to
50
00:02:32.000 --> 00:02:35.919
start diet and exercise, or the first two. In puberty.
51
00:02:35.919 --> 00:02:40.360
Sleep is particularly important, of course, but with diet and
52
00:02:40.400 --> 00:02:47.639
exercise throughout a lifespan, you want to not exclude things
53
00:02:47.680 --> 00:02:50.680
that are helping you. For example, daring puberty, if you're
54
00:02:50.719 --> 00:02:52.599
consuming dairy and then all of a sudden you cut
55
00:02:52.599 --> 00:02:55.719
out all day, dairy can help increase IGF one and
56
00:02:55.759 --> 00:02:56.719
free IGF one.
57
00:02:56.800 --> 00:02:59.680
And just for our audience, maybe you just mention what
58
00:02:59.759 --> 00:03:02.479
I what having enough IGF one can do for us
59
00:03:02.479 --> 00:03:03.639
that's beneficial is.
60
00:03:03.800 --> 00:03:08.080
It helps you grow. It helps with genital development, secondary
61
00:03:08.080 --> 00:03:13.400
sexual characteristics and long bone growth, skin growth, hair growth,
62
00:03:13.439 --> 00:03:14.319
a host of things.
63
00:03:14.439 --> 00:03:18.159
So getting an array of nutrients that include dairy. What
64
00:03:18.199 --> 00:03:20.599
other sorts of nutrients are important during development?
65
00:03:20.759 --> 00:03:23.240
You want to have adequate vitamin D. Vitamin D helps
66
00:03:23.240 --> 00:03:28.039
with testosterone production. It helps again with bone mineralization and
67
00:03:28.400 --> 00:03:32.560
stature after an age of about twenty five, and there's
68
00:03:32.560 --> 00:03:35.280
not a strict cutoff, but up to about an age
69
00:03:35.319 --> 00:03:38.199
of twenty five. Optimizing your growth hormone and IGF one
70
00:03:38.400 --> 00:03:43.000
helps with bone density and bone growth. So from the
71
00:03:43.039 --> 00:03:46.520
dietary standpoint, you want to have enough free estrogen, not
72
00:03:46.639 --> 00:03:49.439
too much when you're growing, but you want to help
73
00:03:50.879 --> 00:03:54.800
basically stockpile bone to prevent a risk of osteoporosis or
74
00:03:54.840 --> 00:03:57.400
thin bones fractures when you're older.
75
00:03:57.479 --> 00:03:59.840
I realize that some of this relates to ethics and
76
00:04:00.199 --> 00:04:02.240
allergies and things of that sort, But would you say that,
77
00:04:02.400 --> 00:04:07.520
on balance, that most people would benefit from eating a
78
00:04:07.560 --> 00:04:12.240
combination of quality proteins from animal sources and non animal
79
00:04:12.280 --> 00:04:16.040
sources fruits, vegetables, and starches. I mean, what do you think,
80
00:04:16.040 --> 00:04:19.079
for instance, about people following a pure carnivore or a
81
00:04:19.199 --> 00:04:22.639
very pure vegan diet in their twenties and thirties.
82
00:04:23.079 --> 00:04:25.800
In their late twenties, it might be a reasonable option.
83
00:04:26.279 --> 00:04:29.199
In early twenties and certainly teens, it is a horrible
84
00:04:29.199 --> 00:04:33.560
idea because it is likely to significantly decrease your free androgens,
85
00:04:33.639 --> 00:04:36.439
so you will have less testosterone actin on receptors through
86
00:04:36.480 --> 00:04:37.279
the body.
87
00:04:37.319 --> 00:04:40.800
Are there any other micronutrients or macronutrients that people in
88
00:04:40.839 --> 00:04:42.680
their twenties and thirties should emphasize.
89
00:04:42.879 --> 00:04:45.720
Fiber is going to be paramount in kind of like
90
00:04:45.800 --> 00:04:48.600
setting your set point of your gut microbiome the rest
91
00:04:48.639 --> 00:04:52.240
of your life. There is prebiotic fiber, which you could
92
00:04:52.240 --> 00:04:55.560
think of as fish food for your good gut microbiome.
93
00:04:55.639 --> 00:04:58.000
Your gut microbiome is kind of like an aquairument or
94
00:04:58.000 --> 00:05:00.560
a fish tank. Any fiber or food that you're putting
95
00:05:00.600 --> 00:05:03.079
in your gut, it's either going to it's going to
96
00:05:03.120 --> 00:05:06.480
skew your gut microbiome towards something that is more beneficial
97
00:05:07.000 --> 00:05:08.079
or more detrimental.
98
00:05:08.399 --> 00:05:12.079
And would you say that the prebiotic fiber and getting
99
00:05:12.160 --> 00:05:15.639
essential fatty acids that would be important to do throughout
100
00:05:15.639 --> 00:05:17.199
the life span or just for the people in their
101
00:05:17.199 --> 00:05:17.759
twenties and.
102
00:05:17.680 --> 00:05:22.360
Thirties throughout the lifespan, particularly important in the teenage, twenties
103
00:05:22.399 --> 00:05:27.040
thirties because it helps with brain development. You're certainly more
104
00:05:27.079 --> 00:05:30.639
of an expert than me when it comes to brain development,
105
00:05:30.680 --> 00:05:34.240
but it does continue to develop really throughout the lifespan,
106
00:05:34.319 --> 00:05:36.279
but certainly through the twenties and thirties as well.
107
00:05:36.360 --> 00:05:38.759
In a previous discussion of ours, I asked you about
108
00:05:39.240 --> 00:05:42.759
caloric restriction and testosterone, and if I recall correctly, the
109
00:05:42.800 --> 00:05:45.279
idea was that if somebody is overweight, they have an
110
00:05:45.319 --> 00:05:48.600
excess fat at a post tissue, then getting rid of
111
00:05:48.600 --> 00:05:50.680
some of that at a post tissue but through chloric
112
00:05:50.759 --> 00:05:53.439
restriction and exercise, provided it's done not too fast in
113
00:05:53.439 --> 00:05:56.759
a healthy way, is going to be beneficial for testosterone
114
00:05:56.800 --> 00:06:00.439
in the long run. But that for individual who are
115
00:06:00.439 --> 00:06:03.040
not carrying an excess of body fat, caloric restriction is
116
00:06:03.079 --> 00:06:07.199
actually going to lower testosterone. First of all, do I
117
00:06:07.240 --> 00:06:11.160
have that correct? And second, are there any addendums to
118
00:06:11.199 --> 00:06:14.199
that that you'd like to give us? Now that's correct.
119
00:06:14.839 --> 00:06:18.720
If you look at an individual in a caloric deficit,
120
00:06:18.879 --> 00:06:22.439
several changes will happen. One is that they'll have less
121
00:06:22.480 --> 00:06:25.759
building blocks for hormones. Another is that they will be
122
00:06:25.800 --> 00:06:28.560
in a catabolic state more often, so that balance of
123
00:06:28.560 --> 00:06:32.639
anabolism and catabolism will be different. They'll likely have less
124
00:06:32.680 --> 00:06:36.759
signaling from growth hormone and IGF one, and they'll also
125
00:06:36.839 --> 00:06:39.680
have the high SHBG that we defined earlier as the
126
00:06:39.680 --> 00:06:43.639
binding protein, so they're free androgens and free estrogens will
127
00:06:43.680 --> 00:06:44.680
go down now.
128
00:06:44.680 --> 00:06:47.399
What are some of the other pillars of creating the
129
00:06:47.439 --> 00:06:49.360
proper environment for hormone optimization.
130
00:06:49.879 --> 00:06:55.600
Stress is probably the next one. During both puberty but
131
00:06:55.639 --> 00:07:00.120
also the twenties and thirties, individuals are figuring out how
132
00:07:00.160 --> 00:07:02.720
they want to cope with stress and also figuring out
133
00:07:02.759 --> 00:07:05.199
what they want to choose to put their effort into.
134
00:07:06.759 --> 00:07:09.560
So if someone is overstressed, then they can have it,
135
00:07:09.600 --> 00:07:13.199
can put all the other lifestyle pillars, and then they
136
00:07:13.199 --> 00:07:17.600
stop dieting, well, they stop exercising, and everything else can
137
00:07:17.639 --> 00:07:18.160
go askew.
138
00:07:18.519 --> 00:07:20.360
What would it be some of the additional things that
139
00:07:20.399 --> 00:07:21.279
everybody should do.
140
00:07:21.600 --> 00:07:24.920
Another one is finding what your purpose is in life.
141
00:07:25.360 --> 00:07:27.720
So I call this spirit, but it's really just the
142
00:07:27.800 --> 00:07:31.800
self actualization component of Maslow's hierarchy of needs, which is
143
00:07:31.839 --> 00:07:34.120
basically your physical needs, your mental needs, and then your
144
00:07:34.120 --> 00:07:36.399
purpose in life which you really like to do.
145
00:07:36.639 --> 00:07:39.439
The idea is not to pick the end goal, is
146
00:07:39.480 --> 00:07:42.759
to pick a goal and then once you reach that goal,
147
00:07:42.839 --> 00:07:45.680
to assess and then pick another goal and so on.
148
00:07:45.759 --> 00:07:47.680
I think sometimes when people hear about picking up purpose
149
00:07:47.680 --> 00:07:49.439
of like ohing goerness, I have to define sort of
150
00:07:49.439 --> 00:07:54.319
like naming oneself, that you actually can change your goals
151
00:07:54.319 --> 00:07:57.279
and purpose over time. I'd like to take a quick
152
00:07:57.279 --> 00:08:00.439
break and acknowledge one of our sponsors, Element Element is
153
00:08:00.439 --> 00:08:02.959
an electrolyte drink that has everything you need and nothing
154
00:08:03.000 --> 00:08:06.800
you don't. That means the electrolytes sodium, magnesium, and potassium
155
00:08:06.800 --> 00:08:09.680
in the correct amounts, but no sugar. Proper hydration is
156
00:08:09.680 --> 00:08:13.079
critical for optimal brain and body function. Even a slight
157
00:08:13.120 --> 00:08:16.959
degree of dehydration can diminish cognitive and physical performance. It's
158
00:08:17.000 --> 00:08:20.399
also important that you get adequate electrolytes. The electrolytes sodium,
159
00:08:20.399 --> 00:08:23.560
magnesium and potassium are vital for functioning of all the
160
00:08:23.560 --> 00:08:26.720
cells in your body, especially your neurons or your nerve cells.
161
00:08:27.120 --> 00:08:29.519
Drinking Element disolved in water makes it very easy to
162
00:08:29.600 --> 00:08:33.320
ensure that you're getting adequate hydration and adequate electrolytes. To
163
00:08:33.360 --> 00:08:36.320
make sure that I'm getting proper amounts of hydration and electrolytes,
164
00:08:36.600 --> 00:08:39.000
I dissolve one packet of Element in about sixteen to
165
00:08:39.039 --> 00:08:40.960
thirty two ounces of water when I first wake up
166
00:08:40.960 --> 00:08:43.279
in the morning, and I drink that basically first thing
167
00:08:43.320 --> 00:08:45.840
in the morning. I'll also drink Element dissolved in water
168
00:08:45.919 --> 00:08:48.799
during any kind of physical exercise that I'm doing, especially
169
00:08:48.840 --> 00:08:50.799
on hot days when I'm sweating a lot and losing
170
00:08:50.840 --> 00:08:54.480
water and electrolytes. Element has a bunch of great tasting flavors.
171
00:08:54.799 --> 00:08:57.399
I love the raspberry, I love the citrus flavor. Right now,
172
00:08:57.440 --> 00:09:01.440
Element has a limited addition lemonade flavor is absolutely delicious.
173
00:09:01.519 --> 00:09:03.200
I hate to say that I love one more than
174
00:09:03.240 --> 00:09:05.759
all the others, but this lemonade flavor is right up
175
00:09:05.799 --> 00:09:09.159
there with my favorite other one, which is raspberry or watermelon. Again,
176
00:09:09.200 --> 00:09:11.240
I can't pick just one flavor. I love them all.

00:09:27.159 --> 00:09:31.320

183
00:09:31.320 --> 00:09:33.519
that people should do, or I should say the key
184
00:09:33.559 --> 00:09:35.840
things that men should do to optimize their hormones. What
185
00:09:35.840 --> 00:09:40.240
do you think is a healthy, sustainable exercise regimen that
186
00:09:40.960 --> 00:09:44.919
anyone can follow that will also support their hormone status.
187
00:09:45.320 --> 00:09:49.039
For really vigorous exercise around three to four times a
188
00:09:49.080 --> 00:09:51.919
week is very sustainable over a long period of time.
189
00:09:52.639 --> 00:09:54.519
On top of that, you could add in three or
190
00:09:54.559 --> 00:09:59.519
four more instances of less vigorous exercise. When they study
191
00:09:59.759 --> 00:10:04.759
the effect of exercise, specifically vigorous exercise, one area that's
192
00:10:04.799 --> 00:10:09.240
been studied is vigorous exercise episodes lasting longer than an hour,
193
00:10:10.080 --> 00:10:13.720
and they usually track it by a rating of perceived exertion,
194
00:10:13.799 --> 00:10:16.879
which isn't perfect and it's not extremely actionable, but it's
195
00:10:16.879 --> 00:10:20.279
helpful for clinical science. But the takeaway from that is basically,
196
00:10:20.919 --> 00:10:27.600
do not. It is not hormonally helpful to train, especially regularly,
197
00:10:27.639 --> 00:10:30.960
train vigorously for longer than an hour.
198
00:10:31.480 --> 00:10:34.960
These days, for better or for worse, I think for worse,
199
00:10:36.120 --> 00:10:41.919
younger guys are asking about and using testosterone replacement therapy
200
00:10:41.960 --> 00:10:46.759
so called TRT. Why in the world would any male
201
00:10:47.159 --> 00:10:52.559
in his teens or twenties or even thirties, whose blood
202
00:10:52.639 --> 00:10:55.799
levels of testosterone and estrogen are at the appropriate levels,
203
00:10:55.879 --> 00:10:59.399
meaning within the normal reference range, why would they take
204
00:10:59.519 --> 00:11:05.080
exogic testosterone Given all the negative effects on fertility, some
205
00:11:05.120 --> 00:11:07.200
of the challenges that it can present, if the dosages
206
00:11:07.200 --> 00:11:10.799
aren't quite right, et cetera, why would they do that? Certainly,
207
00:11:11.080 --> 00:11:15.039
if they are not being paid for a particular endeavor,
208
00:11:15.080 --> 00:11:17.159
like they're not making money. If they are playing as sports,
209
00:11:17.240 --> 00:11:19.039
chances are they're not allowed to do that anyway. It's
210
00:11:19.759 --> 00:11:22.039
on the banned substances list. So to me it just
211
00:11:22.080 --> 00:11:25.840
seems like a crazy idea. But then again, I'm of
212
00:11:25.879 --> 00:11:28.799
a generation that really hasn't thought about doing that stuff
213
00:11:28.879 --> 00:11:32.000
until people were in their forties and fifties or even never.
214
00:11:32.840 --> 00:11:35.440
So is there ever a case for somebody in their
215
00:11:35.519 --> 00:11:39.200
twenties or thirties to take testosterone but if their blood
216
00:11:39.279 --> 00:11:43.039
levels are within the three hundred to nine hundred nanograms
217
00:11:43.039 --> 00:11:44.480
per DESO leader reference range.
218
00:11:44.639 --> 00:11:48.039
You know, everyone has their different reason as far as
219
00:11:48.120 --> 00:11:52.559
like when does the benefit outweigh the detriment? Not very
220
00:11:52.639 --> 00:11:56.919
often if you're in your twenties, and certainly probably almost
221
00:11:56.960 --> 00:11:59.639
hardly never. There's always, you know, rare cases like Coleman
222
00:11:59.679 --> 00:12:04.519
syndrome and whatnot, but almost never if you're very young.
223
00:12:04.919 --> 00:12:07.960
Okay, So for people in their twenties, thirties and beyond forties,
224
00:12:07.960 --> 00:12:11.759
et cetera, whose testosterone and estrogen levels are at the
225
00:12:11.759 --> 00:12:16.720
appropriate ratios and in within the normal reference range libido
226
00:12:16.840 --> 00:12:22.879
energy recovery, et cetera, are feeling least workable for their lifestyle.
227
00:12:23.639 --> 00:12:28.039
For those people, what can they do besides get great sleep,
228
00:12:28.639 --> 00:12:30.519
train but not too hard or too often, et cetera,
229
00:12:30.559 --> 00:12:32.320
et cetera. What are some of the things in the
230
00:12:32.360 --> 00:12:36.720
realm of supplementation that can help them optimize their testosterone
231
00:12:36.720 --> 00:12:42.000
and estrogen without suppressing their own indogenous production of testosterone
232
00:12:42.039 --> 00:12:42.600
and estrogen.
233
00:12:43.240 --> 00:12:46.840
Let's mention. Creatine is the first one. Creatine is interesting
234
00:12:46.879 --> 00:12:49.480
because it has multiple different effects. That helps with amino
235
00:12:49.519 --> 00:12:53.679
acid synthesis. It also helps with oxidative stress. It can
236
00:12:53.720 --> 00:12:56.679
also serve as the backup fuel tank for your monochondria,
237
00:12:56.759 --> 00:13:00.519
so kind of holding backup atp and it does slightly
238
00:13:00.600 --> 00:13:04.279
increase total testosterone and it also increases the conversion of
239
00:13:04.279 --> 00:13:08.840
testosterone to die hydro testosterone, so potentially it's especially useful
240
00:13:09.080 --> 00:13:13.519
in men in their even their teenage years and their twenties.
241
00:13:14.080 --> 00:13:17.240
You mentioned the conversion of testosterone to dihydrag testosterone, and
242
00:13:17.279 --> 00:13:20.559
there is mythology out there that creatine can increase hair loss.
243
00:13:20.559 --> 00:13:23.120
I'm guessing because there's at least one study showing that
244
00:13:23.120 --> 00:13:27.840
creatine can increase DHD dihydrad testosterone, and DHD is one
245
00:13:27.879 --> 00:13:31.440
of the primary hormones that can promote mail pattern baldness.
246
00:13:32.240 --> 00:13:38.159
So the question therefore is does create creatine supplementation increase
247
00:13:38.240 --> 00:13:39.120
the rate of hair.
248
00:13:38.960 --> 00:13:44.639
Loss in each individual? Preventing hair loss is a very
249
00:13:44.679 --> 00:13:47.360
poor reason to creatine because it's not going to take
250
00:13:47.399 --> 00:13:52.559
you to a supra physiologic level. It's not going to
251
00:13:52.679 --> 00:13:58.679
increase your androgens to an unnormal level of binding. So
252
00:13:58.759 --> 00:14:02.080
I feel like this, if that was a reason to
253
00:14:02.159 --> 00:14:04.639
not take creatine for hair loss, then.
254
00:14:04.639 --> 00:14:06.840
That means sorry, you mean hair loss is not a
255
00:14:06.879 --> 00:14:09.080
reason to avoid taking creatine.
256
00:14:09.080 --> 00:14:12.399
Correct hair loss is not a reason to avoid taking creatine.
257
00:14:13.360 --> 00:14:16.440
Think of it as just bringing you to what you
258
00:14:16.559 --> 00:14:21.360
are naturally inclined to have. If your conversion of testosterone
259
00:14:21.399 --> 00:14:24.759
to DHD is already high, then often creatine does not
260
00:14:24.919 --> 00:14:28.879
affect this. It just kind of resets your balance between
261
00:14:28.919 --> 00:14:33.919
testosterone being aromatized to estrogen or being five alpha reduced DHD.
262
00:14:34.759 --> 00:14:36.679
So it's not going to speed up hair loss more
263
00:14:36.720 --> 00:14:40.799
than just naturally being a male does. So in some individuals,
264
00:14:40.879 --> 00:14:44.600
it will have no effect. In some individuals for whatever reason,
265
00:14:44.639 --> 00:14:47.679
they have almost no five alpha reductase activity. It will
266
00:14:47.720 --> 00:14:49.399
return them to natural or normal.
267
00:14:49.840 --> 00:14:53.639
So what other supplement based tools. Can people consider.
268
00:14:53.679 --> 00:14:56.120
Another one we can loop in with creatine is beta en.
269
00:14:56.519 --> 00:14:59.799
Some people are non responders to creatines. You can increase
270
00:14:59.799 --> 00:15:02.600
that to ten grams, or you can use its cousin
271
00:15:02.679 --> 00:15:06.519
beta en to help with amino acid synthesis and shunting
272
00:15:06.559 --> 00:15:10.000
of energy. Along with that, I would put L carnatine
273
00:15:10.399 --> 00:15:11.000
beta en.
274
00:15:11.559 --> 00:15:15.840
Do you recall what dosage people typically would take if
275
00:15:15.840 --> 00:15:18.559
they're a creating non responder.
276
00:15:18.240 --> 00:15:21.440
One to three grams in fact, So yeah, several versions
277
00:15:21.480 --> 00:15:24.559
of creating have beta en mixed in because it helps
278
00:15:24.600 --> 00:15:27.320
with the processing of mathianine and homocysteine.
279
00:15:27.639 --> 00:15:30.320
So if somebody is already taking creatine and likes it
280
00:15:30.360 --> 00:15:33.080
and responds to it, will raise my hand such as myself.
281
00:15:33.279 --> 00:15:38.240
Would adding beta en help or is it redundant with creatine.
282
00:15:37.840 --> 00:15:41.360
Only if their homocystine is persistently elevated. And homocysteine is
283
00:15:41.399 --> 00:15:43.799
kind of like an inflammatory marker that can build up
284
00:15:43.919 --> 00:15:46.320
if you're not converting enough of it down the stream.
285
00:15:46.480 --> 00:15:50.240
How would I know just a blood test, so L carnatine,
286
00:15:50.720 --> 00:15:52.919
What are the ways to take L carnatine. I know
287
00:15:52.960 --> 00:15:55.879
that there's an oral form, so capsules, and there's injectibles,
288
00:15:55.919 --> 00:15:58.360
the injectibles, I think you need a prescription, Is that
289
00:15:58.440 --> 00:15:59.200
right correct?
290
00:15:59.240 --> 00:16:01.360
Do you need a prescript for the injectables or you
291
00:16:01.360 --> 00:16:05.159
should really get a prescription for the injectables. When you
292
00:16:05.200 --> 00:16:08.919
inject it, of course at the supervision of your doctor,
293
00:16:09.000 --> 00:16:12.960
it's usually done intramuscularly. It's an aqueous solution, so it
294
00:16:13.000 --> 00:16:15.000
does not have like an oil or a carrier oil
295
00:16:15.000 --> 00:16:19.519
in it like tr like testosterone esters do. However, if
296
00:16:19.559 --> 00:16:22.559
you inject it to superficially, it's not going to make
297
00:16:22.559 --> 00:16:24.919
a break anything. Often it just burns if you inject
298
00:16:24.960 --> 00:16:29.080
it subcutaneously, and it does not disseminate throughout the body
299
00:16:29.120 --> 00:16:34.240
as well. L carnatine potentially has localized effects if you
300
00:16:34.320 --> 00:16:38.039
inject it, if you ingest it orally, then it has
301
00:16:38.039 --> 00:16:40.879
a very low bioavailability, maybe only ten percent.
302
00:16:41.399 --> 00:16:43.399
So what are the dosages of L carnantine that one
303
00:16:43.440 --> 00:16:46.279
needs to ingest then if they want to get a benefit.
304
00:16:46.360 --> 00:16:50.159
Because I find only ten percent is being absorbed, it's
305
00:16:50.159 --> 00:16:52.360
probably a lot of L carnantine? How much should people
306
00:16:52.360 --> 00:16:52.960
take per day?
307
00:16:53.320 --> 00:16:57.080
Usually I recommend for oral L carnatine between one thousand
308
00:16:57.080 --> 00:17:01.120
milligrams and up to four or five thousand millis so.
309
00:17:01.120 --> 00:17:04.720
Onond to four maybe even five grams.
310
00:17:03.960 --> 00:17:06.680
Correct up to five grams a day. If you're on
311
00:17:06.799 --> 00:17:10.680
that much, especially if you have a dysregulated gut microbiome,
312
00:17:11.160 --> 00:17:14.039
you should be concerned with TMAO, which is a potential
313
00:17:14.079 --> 00:17:18.519
carcinogen that both carnatine and coline can convert into, and
314
00:17:18.559 --> 00:17:21.960
your gut microbiota determine how much that happens.
315
00:17:22.079 --> 00:17:24.440
Is it true that I can offset any negative effects
316
00:17:24.440 --> 00:17:29.279
of alpha gpc coline, that is NL carnatine that I
317
00:17:29.319 --> 00:17:31.799
take by ingesting garlic? Is that right?
318
00:17:31.920 --> 00:17:34.960
There's a compound in garlic called alison. I believe it's
319
00:17:35.000 --> 00:17:37.519
a l I ci in. It's also part of the
320
00:17:37.559 --> 00:17:42.319
scientific name the genus of types of garlic, and this
321
00:17:42.400 --> 00:17:45.839
can help decrease the conversion to TMAO. Berberine actually slightly
322
00:17:45.880 --> 00:17:49.920
decreases the conversion to TMO as well, probably through alteration
323
00:17:49.960 --> 00:17:53.319
of the gut microbiome, and then just optimizing your gut
324
00:17:53.319 --> 00:17:57.119
microbiome can decrease conversion. So not everyone needs allison, but
325
00:17:57.160 --> 00:17:59.440
it's something that you should certainly consider if you were
326
00:17:59.480 --> 00:17:59.880
on a hip.
327
00:18:01.160 --> 00:18:04.119
I'm going to continue to take the six hundred milligrams
328
00:18:04.319 --> 00:18:06.640
of gar like every time I take my L carnatine,
329
00:18:06.640 --> 00:18:08.759
But I'm going to skip the berberene because berberine gives
330
00:18:08.799 --> 00:18:11.400
me brutal headaches, and it makes me create carbohydrates because
331
00:18:11.440 --> 00:18:12.559
it drops my blood sugar.
332
00:18:12.640 --> 00:18:15.640
It has many other effects, including the dawn phenomenon where
333
00:18:15.640 --> 00:18:17.519
it drops your blood sugar when you're sleeping and you
334
00:18:17.519 --> 00:18:18.559
can't even realize it.
335
00:18:18.599 --> 00:18:21.160
Okay, And what we did not talk about is what
336
00:18:21.279 --> 00:18:22.240
L carnatine does.
337
00:18:22.799 --> 00:18:26.640
It's a shuttle, so I think it's named carnatine palmetell
338
00:18:26.960 --> 00:18:31.400
coenzyme A. Basically, it's it just takes nutrients from outside
339
00:18:31.440 --> 00:18:34.359
your mitochondria and puts them in. It also has a
340
00:18:34.480 --> 00:18:37.720
unique effect, well not too unique because tadalophil actually has
341
00:18:37.720 --> 00:18:41.000
this effect as well, is that it increases the density
342
00:18:41.160 --> 00:18:44.519
of the androgen receptor and the cytoplasm of your cells.
343
00:18:45.359 --> 00:18:48.599
So even if your androgen receptor sensitivity doesn't change, and
344
00:18:48.680 --> 00:18:51.799
even if you doesn't testosterone does not change, you will
345
00:18:51.839 --> 00:18:55.279
have more testosterone binding to that increased number of receptors.
346
00:18:55.599 --> 00:18:59.039
Does one need to cycle L carnatine, creatine.
347
00:18:58.519 --> 00:19:01.480
Beta ene into cycle any of those?
348
00:19:01.759 --> 00:19:05.000
What other supplements can one use to try and improve
349
00:19:05.319 --> 00:19:08.599
hormone profiles. And here I realize we're using a very
350
00:19:08.599 --> 00:19:11.000
broad brush because when we say improve hormone profiles, what
351
00:19:11.039 --> 00:19:14.279
are we really talking about? And for me, at least,
352
00:19:14.279 --> 00:19:18.680
I think about the subjective stuff. You know, do people
353
00:19:18.839 --> 00:19:20.759
feel like they are going to have more energy as
354
00:19:20.759 --> 00:19:22.920
a consequence of doing these things? Are they going to
355
00:19:23.000 --> 00:19:25.759
have the more optimized libido? Are they going to have
356
00:19:25.920 --> 00:19:28.680
more optimized recovery from exercise?
357
00:19:28.759 --> 00:19:28.880
Right?
358
00:19:28.920 --> 00:19:31.039
Because I mean, it's not clear to me that taking
359
00:19:31.160 --> 00:19:33.559
one's testosteron from six hundred to eight hundred is always
360
00:19:33.599 --> 00:19:35.960
going to be a good thing, especially if estrogen is
361
00:19:36.000 --> 00:19:39.480
increasing in parallel. That could cause issues. It could certainly
362
00:19:39.480 --> 00:19:41.279
make things better, it could certainly make things worse.
363
00:19:41.519 --> 00:19:44.839
Right, Let's briefly mention vitamin D, which is also a hormone.
364
00:19:44.880 --> 00:19:48.200
It's actually a sterile hormone and have. If you have
365
00:19:48.319 --> 00:19:51.039
deficient vitamin D and you replace it, then you will
366
00:19:51.079 --> 00:19:55.119
optimize your testosterone. It's also mentioned boron, so if you
367
00:19:55.119 --> 00:19:58.680
have a very high SHBG, boron can acutely help lower it,
368
00:19:58.799 --> 00:20:01.680
usually in a dose of five to twelve milligrams per day.
369
00:20:02.160 --> 00:20:06.079
It's not really a sustained effect, but boron is depleted
370
00:20:06.079 --> 00:20:08.839
in soils in many countries. I believe it's very high
371
00:20:08.839 --> 00:20:11.599
in soils in Grease and Turkey, so eating dates or
372
00:20:11.640 --> 00:20:14.519
raisins that are from those areas potentially have more boron.
373
00:20:15.000 --> 00:20:18.160
Boron also might be one of the reasons why the
374
00:20:18.200 --> 00:20:22.519
reference range for testosterone is much higher in those countries
375
00:20:22.880 --> 00:20:23.759
than other countries.
376
00:20:23.920 --> 00:20:26.839
And just to remind people, the SHPG sex hormone mining
377
00:20:26.839 --> 00:20:30.200
globulin is attaching to the diesosterone molecule and limiting the
378
00:20:30.200 --> 00:20:32.720
amount of so called free testosterone that's available to have
379
00:20:32.759 --> 00:20:35.799
its impact on cells. Okay, so, vitamin D three, I'm
380
00:20:35.839 --> 00:20:38.160
guessing you're talking about vitamin D three specifically when you
381
00:20:38.160 --> 00:20:41.000
say vitamin D and then boron five to twelve milligrams
382
00:20:41.039 --> 00:20:43.839
per day, right, and then what are some of the
383
00:20:43.839 --> 00:20:47.720
other things to optimize testosterone that are in supplement form.
384
00:20:48.200 --> 00:20:51.240
We can talk about things that affect the steroidogenesis cascades,
385
00:20:51.279 --> 00:20:53.039
So we could touch on ton cat ali. I know
386
00:20:53.079 --> 00:20:54.920
we've talked about that a little bit before, and.
387
00:20:54.920 --> 00:20:57.759
I'm guessing a number of people probably haven't heard that conversation.
388
00:20:58.119 --> 00:21:01.960
Also known as long jack and net upregulates several different
389
00:21:02.240 --> 00:21:06.680
enzymes in this steroidogenesis cascade and by that what you
390
00:21:06.720 --> 00:21:09.039
mean if and this is another good thing to google.
391
00:21:09.079 --> 00:21:12.200
I think anybody interested in a hormone optimization should understand
392
00:21:12.799 --> 00:21:16.920
where sterol hormones come from. They come usually from cholesterol,
393
00:21:17.319 --> 00:21:19.839
and they can be shunted off to vitamin D very easily.
394
00:21:20.160 --> 00:21:23.640
They can be shunted off to testosterone or estrogens or
395
00:21:23.680 --> 00:21:28.079
progestogens quite easily as well. But tonkat helps with the
396
00:21:28.200 --> 00:21:35.200
conversion of multiple key steps where you synthesize testosterone another
397
00:21:36.640 --> 00:21:39.000
I think of it as like a coenzyme or a cofactor.
398
00:21:39.000 --> 00:21:42.799
An upregulator of these steps is insulin and IGF one.
399
00:21:43.759 --> 00:21:46.359
So a good rule of thumb is if you are
400
00:21:46.480 --> 00:21:49.680
not expecting as much growth hormone insulin and IGF one,
401
00:21:50.039 --> 00:21:54.519
for example, lower carb diets, caloric deficits, you're trying to
402
00:21:54.559 --> 00:21:57.880
cut body fat or body weight, then tonkat is going
403
00:21:57.960 --> 00:22:01.200
to be theoretically specially powerful.
404
00:22:02.160 --> 00:22:04.759
What sorts of dosages of tongua do you recommend to
405
00:22:04.759 --> 00:22:07.000
your patients anywhere.
406
00:22:06.559 --> 00:22:11.079
From three hundred to twelve hundred milligrams a day with tonkat,
407
00:22:11.200 --> 00:22:16.000
you need to be careful with the standardization because if
408
00:22:16.039 --> 00:22:18.599
you're thinking about a general tonkat supplement, which is by
409
00:22:18.640 --> 00:22:23.240
far the most well studied. Then you're looking at the
410
00:22:23.599 --> 00:22:27.759
uryicominone content, which is a plant compound that is likely
411
00:22:27.839 --> 00:22:32.559
the main active pharmacologic effect. So that's the compound that's
412
00:22:32.599 --> 00:22:35.839
having the effect on the body. And if you standardize
413
00:22:35.880 --> 00:22:40.559
the uryicominone very very high, then theoretically you're having more
414
00:22:40.599 --> 00:22:41.920
effect at a lower dose.
415
00:22:42.440 --> 00:22:44.720
My blood work tells me that it causes an increase
416
00:22:44.720 --> 00:22:48.000
in free testosterone for me and also a slight increase
417
00:22:48.039 --> 00:22:51.160
in lutinizing hormone for me. What are some of the
418
00:22:51.200 --> 00:22:54.160
other effects on various hormones that you've observed in the
419
00:22:54.160 --> 00:22:55.359
blood work of your patients?
420
00:22:55.400 --> 00:23:00.319
Taking tongua ali tongkat can also slightly increase DHA And
421
00:23:00.960 --> 00:23:03.640
if you have a very high SHBG. Again, that's the
422
00:23:03.680 --> 00:23:07.160
protein that binds up your androgens, and estrogen's an extremely
423
00:23:07.200 --> 00:23:11.799
important protein. The higher your SHBG, the more it helps
424
00:23:11.839 --> 00:23:16.920
decrease it. So they've studied tongkat in populations with very
425
00:23:17.000 --> 00:23:19.839
normal shbgs and it does nothing for SHBG.
426
00:23:20.319 --> 00:23:23.279
Interesting, does that mean it does nothing for somebody overall?
427
00:23:23.400 --> 00:23:26.200
So if somebody has SHBG that's in the normal range,
428
00:23:26.359 --> 00:23:28.920
will taking tonguat benefit them in any other way.
429
00:23:29.559 --> 00:23:33.319
Yes, it'll increase their total and free testosterone.
430
00:23:33.480 --> 00:23:35.920
I'd like to take a quick break and acknowledge our sponsor,
431
00:23:36.200 --> 00:23:39.880
ag One. Ag One is a vitamin, mineral probiotic drink
432
00:23:39.920 --> 00:23:44.200
that also includes prebiotics and adaptogens. I discovered ag one
433
00:23:44.279 --> 00:23:47.079
way back in twenty twelve, long before I ever had
434
00:23:47.079 --> 00:23:49.440
a podcast, and I've been taking it every day since.
435
00:23:49.720 --> 00:23:51.960
The reason I started taking ag one and the reason
436
00:23:51.960 --> 00:23:54.559
I still take it every day is because ag one is,
437
00:23:54.559 --> 00:23:57.640
to my knowledge, the highest quality and most comprehensive of
438
00:23:57.680 --> 00:24:00.960
the foundational nutritional supplements on the market. Ag One is
439
00:24:01.000 --> 00:24:03.799
designed to support things like gut health, immune health, and
440
00:24:03.880 --> 00:24:06.440
overall energy, and it does so by helping to fill
441
00:24:06.480 --> 00:24:08.720
any gaps that you might have in your daily nutrition.
442
00:24:09.119 --> 00:24:11.359
I get asked pretty much all the time if I
443
00:24:11.359 --> 00:24:13.640
could only take one supplement, what should that supplement be?
444
00:24:14.000 --> 00:24:16.640
And my answer is always ag one. It has just
445
00:24:16.720 --> 00:24:20.079
been so helpful for supporting all aspects of physical health,
446
00:24:20.160 --> 00:24:22.680
mental health, and performance. If you would like to try
447
00:24:22.720 --> 00:24:25.759
ag one, you can go to drinkag one dot com
448
00:24:25.799 --> 00:24:29.000
slash Huberman to get a special offer. For a limited time,
449
00:24:29.079 --> 00:24:31.000
ag one is giving away a free bottle of their
450
00:24:31.039 --> 00:24:34.480
new Omega three coenzyme Q ten product. Omega three and
451
00:24:34.519 --> 00:24:38.559
coenzyme Q ten are known to support cardiovascular health, cellular health,
452
00:24:38.559 --> 00:24:42.240
and energy, generally, brain health, and much more. I personally
453
00:24:42.319 --> 00:24:45.559
take them both every day. Again, go to drinkag one
454
00:24:45.599 --> 00:24:48.240
dot com slash Huberman to get a free bottle of
455
00:24:48.240 --> 00:24:50.759
the new Omega three coenzyme Q ten with your first
456
00:24:50.759 --> 00:24:54.480
ag one subscription. What are some of the other hormones
457
00:24:54.559 --> 00:24:58.119
that you prescribe to your patients who do not want
458
00:24:58.160 --> 00:25:02.240
to go on testosterone replacement therapy or take exogenous DHA
459
00:25:02.440 --> 00:25:03.319
or anything like that.
460
00:25:03.680 --> 00:25:07.359
We could talk about Fidosian next. Fidosia's interesting because it's
461
00:25:07.400 --> 00:25:10.319
a genus of plants. Fidosia agrestis is one of them.
462
00:25:10.359 --> 00:25:14.599
There's many others that are very interesting. That species is
463
00:25:14.839 --> 00:25:18.039
likely the most well studied. And it will increase LH,
464
00:25:18.519 --> 00:25:21.880
so I would not consider it an LH mimetic, so
465
00:25:21.920 --> 00:25:24.599
it doesn't really mimic it, but it increases the release
466
00:25:24.640 --> 00:25:27.240
of lutinizing a hormone from the pituitary that's a hormone
467
00:25:27.240 --> 00:25:30.880
that binds to the LATEG cell, to the LT receptor,
468
00:25:30.960 --> 00:25:34.680
kind of like HGG does, and it will increase the
469
00:25:34.799 --> 00:25:36.200
release of testosterone.
470
00:25:36.400 --> 00:25:39.880
What dosages do you have patient's stake. I've heard of
471
00:25:40.480 --> 00:25:43.599
some potential toxicity to the testicular cells.
472
00:25:43.799 --> 00:25:46.119
There is one study, and this is a rat study,
473
00:25:46.200 --> 00:25:49.599
but you can equate the dose of toxicity in rats
474
00:25:49.640 --> 00:25:52.680
in humans. They did not give these rats any antioxidants.
475
00:25:53.160 --> 00:25:58.079
But it increases a couple different like pro inflammatory markers.
476
00:25:58.119 --> 00:26:01.880
One is GGT or gamma gluten transferrace comes from both
477
00:26:01.920 --> 00:26:04.839
the testes and the liver, and one is alkaline phosphatase
478
00:26:05.079 --> 00:26:08.480
also known as alk FOSS, again coming from both areas.
479
00:26:08.880 --> 00:26:11.680
There are several different ways that you can attenuate this increase,
480
00:26:11.720 --> 00:26:13.400
and you can also just check to see if you
481
00:26:13.440 --> 00:26:17.519
have increased in the rat dose that equates with humans
482
00:26:17.519 --> 00:26:20.519
that had no effect. So the safe dose was an
483
00:26:20.599 --> 00:26:23.079
average of three hundred milligrams a day.
484
00:26:22.960 --> 00:26:25.599
So that would be three hundred milligrams a day in humans.
485
00:26:26.240 --> 00:26:28.920
Is the dosage that did not have toxicity.
486
00:26:29.039 --> 00:26:33.880
Correct correct, And often even if there is toxicity in rats,
487
00:26:33.960 --> 00:26:37.039
there is not toxicity humans, so it's not directly equitable,
488
00:26:37.559 --> 00:26:41.240
but to be safe, another regimen that I have people
489
00:26:41.240 --> 00:26:44.039
take is six hundred milligrams every other day or six
490
00:26:44.160 --> 00:26:47.799
hundred milligrams three times a week, often Monday, Wednesday, Friday.
491
00:26:48.279 --> 00:26:50.680
My understanding is that nowadays a lot of people are
492
00:26:50.759 --> 00:26:53.799
using testosterone. Let's not even call it replacement therapy, because
493
00:26:53.799 --> 00:26:56.480
some of these people have six hundred, seven hundred or
494
00:26:56.519 --> 00:26:59.200
even you know, eight hundred nine a gram peresile to read,
495
00:26:59.279 --> 00:27:02.599
So not replacing anything that is diminished. They're just trying
496
00:27:02.640 --> 00:27:05.599
to augment what's already there, increase what's already there. My
497
00:27:05.720 --> 00:27:09.240
understanding is that taking a low dose more frequently is
498
00:27:09.279 --> 00:27:11.680
going to be more beneficial than the kind of old
499
00:27:11.680 --> 00:27:14.119
school way of giving you know, one hundred or even
500
00:27:14.119 --> 00:27:17.160
two hundred milligrams in a single injection once every two weeks.
501
00:27:17.400 --> 00:27:19.480
Is that right? And what do you do with your patients?
502
00:27:19.599 --> 00:27:21.599
So let me give you a hypothetical. Somebody comes into
503
00:27:21.599 --> 00:27:26.680
your office. There their blood work and they have blood
504
00:27:26.720 --> 00:27:30.599
levels of let's say, six hundred anagrams per deestly or estosterone.
505
00:27:30.640 --> 00:27:34.319
Their estrogen is also in normal range. Everything else checks out,
506
00:27:34.640 --> 00:27:38.359
but they're complaining of you know, slightly diminished libido, slightly
507
00:27:38.400 --> 00:27:43.079
poor recovery from workouts, maybe you know, reduce motivation and drive,
508
00:27:43.119 --> 00:27:46.160
although no major depression. And you come to the conclusion
509
00:27:46.160 --> 00:27:50.279
that testosterone therapy. Not replacement, but testosterone therapy might be
510
00:27:50.279 --> 00:27:53.880
a good option to explore. What's a typical dosage range
511
00:27:54.119 --> 00:27:58.559
and frequency of administration range that you might consider exploring.
512
00:27:59.119 --> 00:28:02.200
Some of this depends on SHBG and free testosterone as well.
513
00:28:02.240 --> 00:28:05.039
So if that same individual had a very high SHBG,
514
00:28:05.079 --> 00:28:07.240
which again is the binding protein that binds up the
515
00:28:07.279 --> 00:28:11.000
testosterone and all androgens and estrogens, if it is extremely
516
00:28:11.079 --> 00:28:15.000
high and they have a free testosterone of two, then
517
00:28:15.000 --> 00:28:17.440
they might need a different dose because they need enough
518
00:28:17.480 --> 00:28:23.880
testosterone in order to have a normal uganadol free testosterone.
519
00:28:24.319 --> 00:28:27.799
But a general normal dosing range, especially for someone starting,
520
00:28:27.880 --> 00:28:31.000
is around one hundred to one hundred and twenty milligrams
521
00:28:31.319 --> 00:28:34.880
divided over the course of a week, usually either every
522
00:28:34.960 --> 00:28:38.160
other day or three times a week, occasionally twice a week.
523
00:28:38.680 --> 00:28:41.839
Many people with SHBG a bit higher can get away
524
00:28:41.880 --> 00:28:44.759
pretty easily with twice a week. This is assuming that
525
00:28:44.759 --> 00:28:47.200
the ester is sipienate or a nantheate.
526
00:28:46.920 --> 00:28:51.680
So two sixty milligram injections of testosteronecipientate.
527
00:28:50.759 --> 00:28:52.799
Per week, yeah, very common dosing to.
528
00:28:52.839 --> 00:28:54.799
Hit that one hundred and twenty milligrams per week as
529
00:28:54.880 --> 00:28:56.559
kind of the typical average.
530
00:28:56.160 --> 00:28:59.839
Erect and I would consider this like a physiologic yugan adult.
531
00:29:00.680 --> 00:29:04.000
For many people, even two hundred milligrams a week is
532
00:29:04.519 --> 00:29:07.200
far above the reference range. All of this is said
533
00:29:07.200 --> 00:29:10.839
with the caveat that testosterone is normally released in a
534
00:29:10.920 --> 00:29:13.400
pulsatile manner, so it's high in the morning, low in
535
00:29:13.400 --> 00:29:19.480
the evening. Whereas if you're on testosterone therapy, then you're
536
00:29:19.519 --> 00:29:22.359
going to have a steady state, so your testosterone level
537
00:29:22.400 --> 00:29:24.599
is going to be pretty much the same even in
538
00:29:24.640 --> 00:29:25.119
the evening.
539
00:29:25.480 --> 00:29:28.200
In your experience, when patients do that, they I'm guessing
540
00:29:28.240 --> 00:29:31.039
they report the normal constellation of positive effects, you know,
541
00:29:31.079 --> 00:29:35.400
improved mood, improved energy, improved sleep, recovery, et cetera. What
542
00:29:35.440 --> 00:29:38.400
are some of the hazards or things that can crop
543
00:29:38.519 --> 00:29:41.920
up in blood work or just subjectively that can be
544
00:29:41.960 --> 00:29:44.119
warning signs that even a dosage of one hundred and
545
00:29:44.119 --> 00:29:46.920
twenty milligrams divided into these two or three dosages per
546
00:29:46.920 --> 00:29:48.119
week is too high.
547
00:29:48.279 --> 00:29:51.440
So this is when you really have to be at
548
00:29:51.519 --> 00:29:55.559
least well versed in every organ system, not just the
549
00:29:55.880 --> 00:30:00.359
ganadal like you know, genital system you need do have
550
00:30:01.200 --> 00:30:06.440
you know, dermatology, prowess. Acne is very common change lots
551
00:30:06.480 --> 00:30:10.000
of different skin pathologies or even bruising can be related
552
00:30:10.000 --> 00:30:13.519
to hormone replacement. Hair Loss is very common to see
553
00:30:13.519 --> 00:30:17.880
as well mental status changes. It could occasionally it even
554
00:30:17.880 --> 00:30:21.200
induces a manic or a bipolar episode because testosterone is
555
00:30:21.240 --> 00:30:25.799
also dopaminergic, and then cardiovascularly, not just in the heart,
556
00:30:25.960 --> 00:30:30.079
but also concerns for like microvascular a schemic disease, ferret
557
00:30:30.200 --> 00:30:33.640
and build up because the estrogen also increases, and then
558
00:30:34.079 --> 00:30:37.880
fertility concerns as well, and lipid concerns too, So you
559
00:30:37.920 --> 00:30:44.240
really have to be you know, hematologist, dermatologist, cardiologists, lipidologists,
560
00:30:44.279 --> 00:30:45.200
the whole nine yards.
561
00:30:45.599 --> 00:30:51.039
So another reason or set of reasons rather to if
562
00:30:51.079 --> 00:30:54.079
one is considering using testosterone therapy to really do this
563
00:30:54.319 --> 00:30:57.960
in close communication with a really good physician, because that's
564
00:30:58.000 --> 00:30:59.519
a lot to monitor. Knowing whether or not you have
565
00:30:59.519 --> 00:31:01.759
acting or not is one thing, but knowing whether or
566
00:31:01.799 --> 00:31:04.119
not your LDL is going up, your ABOB is going up,
567
00:31:04.119 --> 00:31:05.839
that's a whole other biz. And that needs to be
568
00:31:05.880 --> 00:31:07.759
done through blood work, is what I'm hearing.
569
00:31:08.119 --> 00:31:11.839
Correct And if your physician that is managing or prescribing
570
00:31:11.920 --> 00:31:17.079
your testosterone therapy or your HRT is not well versed
571
00:31:17.079 --> 00:31:19.279
in these systems. You would want him or her to
572
00:31:19.319 --> 00:31:21.920
be part of an interdisciplinary team where they have other
573
00:31:22.000 --> 00:31:24.160
experts that can monitor those systems.
574
00:31:24.440 --> 00:31:26.880
There are males out there who want to increase their
575
00:31:26.920 --> 00:31:31.640
testosterone and other hormones, maybe growth hormone, et cetera, who
576
00:31:31.839 --> 00:31:35.599
opt to not take exogenous testosterones, no cream, no pellet,
577
00:31:35.680 --> 00:31:40.519
no no pill, no injectable scipionate, but decide to take
578
00:31:40.720 --> 00:31:44.720
chlmophin a couple times a week. My understanding, I've never
579
00:31:44.720 --> 00:31:46.839
done this, I would say if I had. My understanding
580
00:31:46.920 --> 00:31:52.240
is that taking chlomophin maybe two fifty milligram tablets a week,
581
00:31:52.359 --> 00:31:55.079
is what I hear people are doing, will increase what
582
00:31:55.279 --> 00:32:00.519
lutinizing hormone, the various estrogen receptor subunits. Did you explain
583
00:32:00.559 --> 00:32:03.640
how chomophin would benefit anyone and is this a good strategy.
584
00:32:03.920 --> 00:32:06.039
I'm hearing that it's being done quite a lot now.
585
00:32:06.559 --> 00:32:09.839
It will increase testosterone in a dose to pendent manner,
586
00:32:10.359 --> 00:32:13.359
but it has many other pharmacodynamic effects, which is the
587
00:32:13.359 --> 00:32:16.119
effect of the drug on the body other than its
588
00:32:16.160 --> 00:32:19.440
effect on the hypothalamus in the pituitary so in the hypothalamus,
589
00:32:19.480 --> 00:32:24.720
and the pituitary. It does what's called negative feedback inhibition,
590
00:32:26.240 --> 00:32:29.720
or it blocks the axgen of estrogen, so it crowds
591
00:32:29.759 --> 00:32:34.400
out estrogen from the estrogen receptor on the hypothalamus and
592
00:32:34.440 --> 00:32:35.240
the pituitary.
593
00:32:35.480 --> 00:32:38.359
Why would I want to take something that would increase
594
00:32:38.480 --> 00:32:42.119
the activity of an estrogen receptor. I just can't find
595
00:32:42.160 --> 00:32:43.160
the rationale for that.
596
00:32:43.559 --> 00:32:47.000
The main rationale behind taking a serm is as a
597
00:32:47.319 --> 00:32:51.720
very temporary measure that is not going to suppress pituitary
598
00:32:51.960 --> 00:32:57.039
or hypothlemic function. If your testosterone is just so drastically
599
00:32:57.079 --> 00:33:01.000
low that it is unlikely to recover anyone anyway. So
600
00:33:01.240 --> 00:33:04.680
most of the time it is not clinically useful and
601
00:33:05.720 --> 00:33:08.759
SERMs should not be prescribed very often, certainly not as
602
00:33:08.880 --> 00:33:14.720
long term testosterone replacement or testosterone optimization in most individuals.
603
00:33:14.759 --> 00:33:20.359
There's always exceptions to everything. But there's five different estrogen
604
00:33:20.519 --> 00:33:26.079
and estrogen related receptors. There's two main estrogen receptors and chlomid,
605
00:33:26.200 --> 00:33:30.119
and every serm has a very unique profile because they
606
00:33:30.240 --> 00:33:34.400
selectively inhibit some receptors in some tissues but not other
607
00:33:34.440 --> 00:33:39.039
receptors and other tissues. For example, chlomid can inhibit receptors
608
00:33:39.039 --> 00:33:42.680
that are in the eye, and it can cause visual
609
00:33:42.759 --> 00:33:48.799
changes blurry vision, especially at higher doses, and it also
610
00:33:49.160 --> 00:33:51.960
acts in every other tissue with the body, so side
611
00:33:51.960 --> 00:33:56.599
effects from chlomid and other selective estrogen receptor modifiers are
612
00:33:56.720 --> 00:33:57.279
very common.
613
00:33:57.640 --> 00:33:59.559
I'd like to take a quick break to acknowledge one
614
00:33:59.599 --> 00:34:03.960
of our sauncers, David. David makes protein bars unlike any other.
615
00:34:04.359 --> 00:34:07.799
Their newest bar, the Bronze Bar, has twenty grams of protein,
616
00:34:07.920 --> 00:34:10.880
only one hundred and fifty calories and zero grams of sugar.
617
00:34:11.280 --> 00:34:13.639
I have to say these are the best tasting protein
618
00:34:13.679 --> 00:34:16.719
bars I've ever had, and I've tried a lot of
619
00:34:16.760 --> 00:34:19.480
protein bars over the years. These new David bars have
620
00:34:19.480 --> 00:34:22.599
a marshmallow base and they're covered in chocolate coating, and
621
00:34:22.679 --> 00:34:26.519
they're absolutely incredible. I of course eat regular whole foods.
622
00:34:26.519 --> 00:34:29.480
I eat meat, chicken, fish, eggs, fruits, vegetables, et cetera.
623
00:34:29.880 --> 00:34:31.480
But I also make it a point to eat one
624
00:34:31.559 --> 00:34:34.039
or two David bars per day as a snack, which
625
00:34:34.119 --> 00:34:36.079
makes it easy to hit my protein goal of one
626
00:34:36.079 --> 00:34:38.440
gram of protein per pound of body weight, and that
627
00:34:38.519 --> 00:34:40.920
allows me to take in the protein I need without
628
00:34:40.920 --> 00:34:44.559
consuming excess calories. I love all the David bronze bar flavors,
629
00:34:44.800 --> 00:34:48.880
including cookie dough, caramel chocolate, double chocolate, peanut butter chocolate.
630
00:34:49.039 --> 00:34:51.960
They all actually taste like candy bars. Again, they're amazing,
631
00:34:52.280 --> 00:34:54.360
but again they have no sugar, and they have twenty
632
00:34:54.400 --> 00:34:57.000
grams of protein with just one hundred and fifty calories.
633
00:34:57.440 --> 00:34:59.320
If you'd like to try David, you can go to
634
00:34:59.440 --> 00:35:02.679
David prote dot com slash huberman. Right now, David is
635
00:35:02.679 --> 00:35:05.079
offering a deal where if you buy four cartons, you
636
00:35:05.119 --> 00:35:07.320
get the fifth carton for free. You can also find
637
00:35:07.400 --> 00:35:10.320
David on Amazon or in stores such as Target, Walmart,
638
00:35:10.360 --> 00:35:12.920
and Kroger. Again, to get the fifth carton for free,
639
00:35:13.039 --> 00:35:17.480
go to David Protein dot com slash huberman. Alcohol. Does
640
00:35:17.519 --> 00:35:21.039
it increase a romantase the enz on the converse distosterone
641
00:35:21.039 --> 00:35:24.960
into estrogen or not? And is there a dose dependence there?
642
00:35:25.559 --> 00:35:29.119
It significantly? Does there is a dose dependence? In general,
643
00:35:29.599 --> 00:35:34.320
I would not recommend more than three to four, you know,
644
00:35:34.400 --> 00:35:38.159
standard drinks. One huge glass of wine is probably five
645
00:35:38.239 --> 00:35:41.400
standard drinks every two weeks. The other thing to keep
646
00:35:41.400 --> 00:35:43.559
in mind with alcohol is as a lot of calories
647
00:35:43.719 --> 00:35:47.000
seven kilo calories program almost as much as fat which
648
00:35:47.039 --> 00:35:50.079
is nine. And then it's also very gaba urgic, so
649
00:35:50.800 --> 00:35:57.280
it can activate inhibitory neurotransmission, and that can also affect
650
00:35:57.320 --> 00:36:01.480
how many how much LH and FSH is released, so
651
00:36:01.519 --> 00:36:06.039
that can also decrease testosterone, almost kind of similar to
652
00:36:06.159 --> 00:36:09.079
how opiates can decrease testosterone.
653
00:36:09.199 --> 00:36:11.760
I want to go back to the prostate and talk
654
00:36:11.760 --> 00:36:14.639
to you about something that's kind of a newer emerging trend.
655
00:36:14.760 --> 00:36:16.800
I know that you've talked to a little bit about
656
00:36:16.800 --> 00:36:20.519
this in previous podcasts that a number of men, I
657
00:36:20.519 --> 00:36:24.519
should say a number of physicians are prescribing low dose
658
00:36:24.599 --> 00:36:28.360
to dalophil also known as cialis, to their male patients,
659
00:36:28.599 --> 00:36:31.199
so in dosage ranges of like two point five milligrams
660
00:36:31.239 --> 00:36:34.079
to five milligrams per day, but not for a rectile dysfunction,
661
00:36:34.159 --> 00:36:37.760
but rather for improving prostate health, and presumably they get
662
00:36:37.800 --> 00:36:40.320
sort of a boost in terms of blood flow to
663
00:36:40.360 --> 00:36:43.880
the genitalia as well, but again not specifically a deal
664
00:36:43.920 --> 00:36:47.679
with a rectile dysfunction, but to deal with prostate health
665
00:36:47.760 --> 00:36:50.400
and blood flow to the prostate. Is that something that
666
00:36:50.440 --> 00:36:54.199
you sometimes often prescribe to your patients, and of what age?
667
00:36:54.559 --> 00:36:58.159
Toad Alifil is a very underrated medication. The age would
668
00:36:58.199 --> 00:37:02.440
kind of depend on the indication, So ted aalaphil is
669
00:37:02.559 --> 00:37:05.719
also a blood pressure medication. It can very slightly decrease
670
00:37:05.719 --> 00:37:09.440
blood pressure, especially at higher doses. At higher doses at
671
00:37:09.519 --> 00:37:12.800
theorem a high dose would be twenty miligrams, not two
672
00:37:12.800 --> 00:37:17.079
point five miligrams, but consistently it can somewhat affect with
673
00:37:17.199 --> 00:37:19.199
the cones in the eye that have to do with
674
00:37:19.280 --> 00:37:21.920
red and green sight, although if you remove it, that
675
00:37:22.000 --> 00:37:25.079
effect is reversed. So basically, if you don't need really
676
00:37:25.079 --> 00:37:27.760
really good red green discrimination, you can take higher doses,
677
00:37:28.159 --> 00:37:31.239
but in general I recommend no higher than ten miligrams
678
00:37:31.239 --> 00:37:37.280
a day, usually just two or five miligrams. One other
679
00:37:37.440 --> 00:37:40.440
benefit or other use of tadalophil is that it increases
680
00:37:40.519 --> 00:37:44.320
the density of the androgen receptor, similarly to L carnotine,
681
00:37:45.599 --> 00:37:48.840
so that's an interesting benefit. Another benefit is that if
682
00:37:48.880 --> 00:37:51.679
you give it to people with nolturia, which is urinating
683
00:37:51.719 --> 00:37:54.480
at night, in general, it will cut the episodes in half,
684
00:37:54.639 --> 00:37:57.199
so it could go from two to one, which can
685
00:37:57.239 --> 00:38:00.000
make a big difference for your sleep, which will secondarily
686
00:38:00.079 --> 00:38:02.760
make a big difference for your growth. Hormone and intostosterone optimization.
687
00:38:03.119 --> 00:38:05.920
Interesting. So you said two point five to five milligrams
688
00:38:05.920 --> 00:38:09.440
per day is kind of typical for these prostate enhancing effects. Yes,
689
00:38:10.000 --> 00:38:13.800
I get a lot of questions about drugs to offset
690
00:38:13.840 --> 00:38:16.320
hair loss. Most of those drugs are going to operate
691
00:38:16.360 --> 00:38:19.000
through the DHD system, the DEHYDRAGSI stosterone system for the
692
00:38:19.039 --> 00:38:21.280
reasons we talked about before, DHG receptors being on the
693
00:38:21.280 --> 00:38:24.199
scalp and causing beard growth on the face. Is it
694
00:38:24.280 --> 00:38:27.440
the case that a number of people taking things like
695
00:38:27.519 --> 00:38:31.519
Propecia and other things to block the DHT or disrupt
696
00:38:31.559 --> 00:38:36.360
the DHT pathway are going to experience diminished sex drive,
697
00:38:36.440 --> 00:38:40.800
diminished you know, kind of motivation and general vigor. And
698
00:38:40.840 --> 00:38:44.320
if so, are there alternatives like topical DHT antagonists that
699
00:38:44.360 --> 00:38:47.440
they might use if they want to keep their hair
700
00:38:47.840 --> 00:38:49.320
but not have those negative effects.
701
00:38:50.000 --> 00:38:53.559
Many people that have just a bit of predisposition, they
702
00:38:53.599 --> 00:38:58.760
can use things that are topical anti androgens. Ketoconazola is
703
00:38:58.760 --> 00:39:00.920
one of them. Caffeine is actually another one.
704
00:39:01.000 --> 00:39:03.480
Wait, you have to explain how this works. How do
705
00:39:03.559 --> 00:39:05.519
people get caffeine into the hair of ollicle?
706
00:39:05.920 --> 00:39:10.280
Topically, the caffeine enters the scalp and crowds out like
707
00:39:10.559 --> 00:39:13.679
somewhat crowds out the androgen. It is a weak effect.
708
00:39:14.280 --> 00:39:18.239
It's likely just strong enough to be clinically significant. Usually
709
00:39:18.280 --> 00:39:22.119
caffeine is put into formulations with other things like ketoconazol
710
00:39:22.320 --> 00:39:26.960
that are also weak anti androgens. Of notes, spronlactone can
711
00:39:27.039 --> 00:39:30.599
be prescribed topically, but it is absorbed systemically because the
712
00:39:30.639 --> 00:39:34.519
size of the molecule, So unless your doctor specifically prescribes
713
00:39:34.559 --> 00:39:36.840
that for you, especially as a male, do not use
714
00:39:36.880 --> 00:39:42.800
topical spronalactone. Topical finasteride is also a smaller molecule, so
715
00:39:42.880 --> 00:39:47.000
it is also systemically absorbed, but it is not extremely
716
00:39:47.039 --> 00:39:51.000
well systemically absorbed. If you take topical phinasteride, then usually
717
00:39:51.039 --> 00:39:55.519
your systemic DHT will decrease by about thirty percent. Topical
718
00:39:55.559 --> 00:39:59.639
detastoride is likely a tiny bit systemically absorbed, but it's
719
00:39:59.719 --> 00:40:02.360
unique because it's half life is much faster at a
720
00:40:02.400 --> 00:40:06.440
lower dose, So topical do testeride will not affect your
721
00:40:06.480 --> 00:40:09.360
systemic DHD at all, And I've seen this anecdotally on
722
00:40:09.480 --> 00:40:11.960
many people on topical do testeride therapy.
723
00:40:12.360 --> 00:40:14.960
On behalf of the audience, and just for myself, thank
724
00:40:15.039 --> 00:40:17.320
you so much. You have an immense amount of knowledge
725
00:40:17.320 --> 00:40:20.239
and you're exquisitely good at sharing it with people in
726
00:40:20.280 --> 00:40:22.679
an actual way, So thank you, my pleasure,
1
00:00:00.200 --> 00:00:04.160
Welcome to Huberman Lab Essentials, where we revisit past episodes
2
00:00:04.400 --> 00:00:07.639
for the most potent and actionable science based tools for
3
00:00:07.759 --> 00:00:12.800
mental health, physical health, and performance. I'm Andrew Huberman, and
4
00:00:12.839 --> 00:00:16.559
I'm a professor of neurobiology and ophthalmology at Stanford School
5
00:00:16.559 --> 00:00:20.280
of Medicine, and now for my discussion with doctor Kyle Gillette.
6
00:00:20.519 --> 00:00:23.239
Doctor Gillette, great to have you back, Great to be back.
7
00:00:23.239 --> 00:00:23.559
Thank you.
8
00:00:24.079 --> 00:00:26.879
I'd like to begin with a question about what all
9
00:00:26.960 --> 00:00:30.440
males ought to do in order to optimize their hormones.
10
00:00:30.760 --> 00:00:33.200
What should they be doing, what should they avoid doing?
11
00:00:33.439 --> 00:00:35.719
If the goal is to have a long arc of
12
00:00:35.799 --> 00:00:38.600
healthy hormone optimization throughout the lifespan.
13
00:00:38.560 --> 00:00:41.960
There's many things that you should do. An analogy that
14
00:00:42.039 --> 00:00:44.640
I often make is when there's a brand new car
15
00:00:44.679 --> 00:00:47.000
that comes off the assembly line, you do a full
16
00:00:47.079 --> 00:00:49.560
scope of diagnostic workup, hook it up to the computer.
17
00:00:50.119 --> 00:00:51.439
And I think we should do the same thing with
18
00:00:51.520 --> 00:00:55.079
humans as well. Dear, in puberty, you know, obviously you're
19
00:00:55.119 --> 00:00:59.240
a functioning human, but I would say there's still development,
20
00:00:59.479 --> 00:01:02.479
and I think the human always develops. I don't think
21
00:01:02.479 --> 00:01:05.879
development ever ends, but you want to monitor that progress
22
00:01:05.920 --> 00:01:08.519
across a person's lifespan.
23
00:01:09.040 --> 00:01:11.280
What do you think are the key things to look
24
00:01:11.319 --> 00:01:13.920
for in blood work? I mean, testosterone is always the
25
00:01:14.040 --> 00:01:16.640
topic that comes up in the context of male hormone optimization,
26
00:01:16.680 --> 00:01:18.200
but certainly there are a lot of other hormones that
27
00:01:18.200 --> 00:01:19.120
are important as well.
28
00:01:19.840 --> 00:01:22.560
And with testosterone, you want to get either testosterone in
29
00:01:22.560 --> 00:01:25.000
an SHBG or a free testosterone.
30
00:01:25.000 --> 00:01:27.319
Could you define SHBG for our listeners please.
31
00:01:27.400 --> 00:01:30.280
It is sex hormone binding globulin. It is the protein
32
00:01:30.359 --> 00:01:33.879
that binds up all androgens and estrogen to the body.
33
00:01:34.239 --> 00:01:38.439
So the stronger the androgen, the stronger it binds. During puberty,
34
00:01:39.200 --> 00:01:43.879
strong androgens, especially DHT, which is the strongest bioidentical androgen,
35
00:01:44.599 --> 00:01:49.719
has a huge role a prominent role in secondary sexual characteristics.
36
00:01:50.239 --> 00:01:53.359
And if your SHBG is very high, then your DHT
37
00:01:53.599 --> 00:01:56.719
can run higher because it's not metabolized, but there's not
38
00:01:56.799 --> 00:01:59.359
quite as much free DHD, So you want to balance
39
00:01:59.400 --> 00:02:04.719
between a high enough free DHD and a high enough TOTALDHD.
40
00:02:05.000 --> 00:02:08.240
So, assuming that there's no major intervention, how often do
41
00:02:08.240 --> 00:02:10.639
you recommend that people get their blood work.
42
00:02:10.439 --> 00:02:15.000
Done using shared decision making with their physician. Usually a
43
00:02:15.000 --> 00:02:16.960
good follow up is about six months.
44
00:02:16.719 --> 00:02:19.360
So on a daily basis, maybe you could just take
45
00:02:19.400 --> 00:02:22.560
us through the arc of a day and push out
46
00:02:22.560 --> 00:02:24.479
some of the protocols that you use or the things
47
00:02:24.520 --> 00:02:26.360
that you'd like to see your male patients use in
48
00:02:26.479 --> 00:02:29.479
order to try and optimize their hormone status.
49
00:02:29.599 --> 00:02:31.919
I'll briefly touch on some of the lifestyle pillars to
50
00:02:32.000 --> 00:02:35.919
start diet and exercise, or the first two. In puberty.
51
00:02:35.919 --> 00:02:40.360
Sleep is particularly important, of course, but with diet and
52
00:02:40.400 --> 00:02:47.639
exercise throughout a lifespan, you want to not exclude things
53
00:02:47.680 --> 00:02:50.680
that are helping you. For example, daring puberty, if you're
54
00:02:50.719 --> 00:02:52.599
consuming dairy and then all of a sudden you cut
55
00:02:52.599 --> 00:02:55.719
out all day, dairy can help increase IGF one and
56
00:02:55.759 --> 00:02:56.719
free IGF one.
57
00:02:56.800 --> 00:02:59.680
And just for our audience, maybe you just mention what
58
00:02:59.759 --> 00:03:02.479
I what having enough IGF one can do for us
59
00:03:02.479 --> 00:03:03.639
that's beneficial is.
60
00:03:03.800 --> 00:03:08.080
It helps you grow. It helps with genital development, secondary
61
00:03:08.080 --> 00:03:13.400
sexual characteristics and long bone growth, skin growth, hair growth,
62
00:03:13.439 --> 00:03:14.319
a host of things.
63
00:03:14.439 --> 00:03:18.159
So getting an array of nutrients that include dairy. What
64
00:03:18.199 --> 00:03:20.599
other sorts of nutrients are important during development?
65
00:03:20.759 --> 00:03:23.240
You want to have adequate vitamin D. Vitamin D helps
66
00:03:23.240 --> 00:03:28.039
with testosterone production. It helps again with bone mineralization and
67
00:03:28.400 --> 00:03:32.560
stature after an age of about twenty five, and there's
68
00:03:32.560 --> 00:03:35.280
not a strict cutoff, but up to about an age
69
00:03:35.319 --> 00:03:38.199
of twenty five. Optimizing your growth hormone and IGF one
70
00:03:38.400 --> 00:03:43.000
helps with bone density and bone growth. So from the
71
00:03:43.039 --> 00:03:46.520
dietary standpoint, you want to have enough free estrogen, not
72
00:03:46.639 --> 00:03:49.439
too much when you're growing, but you want to help
73
00:03:50.879 --> 00:03:54.800
basically stockpile bone to prevent a risk of osteoporosis or
74
00:03:54.840 --> 00:03:57.400
thin bones fractures when you're older.
75
00:03:57.479 --> 00:03:59.840
I realize that some of this relates to ethics and
76
00:04:00.199 --> 00:04:02.240
allergies and things of that sort, But would you say that,
77
00:04:02.400 --> 00:04:07.520
on balance, that most people would benefit from eating a
78
00:04:07.560 --> 00:04:12.240
combination of quality proteins from animal sources and non animal
79
00:04:12.280 --> 00:04:16.040
sources fruits, vegetables, and starches. I mean, what do you think,
80
00:04:16.040 --> 00:04:19.079
for instance, about people following a pure carnivore or a
81
00:04:19.199 --> 00:04:22.639
very pure vegan diet in their twenties and thirties.
82
00:04:23.079 --> 00:04:25.800
In their late twenties, it might be a reasonable option.
83
00:04:26.279 --> 00:04:29.199
In early twenties and certainly teens, it is a horrible
84
00:04:29.199 --> 00:04:33.560
idea because it is likely to significantly decrease your free androgens,
85
00:04:33.639 --> 00:04:36.439
so you will have less testosterone actin on receptors through
86
00:04:36.480 --> 00:04:37.279
the body.
87
00:04:37.319 --> 00:04:40.800
Are there any other micronutrients or macronutrients that people in
88
00:04:40.839 --> 00:04:42.680
their twenties and thirties should emphasize.
89
00:04:42.879 --> 00:04:45.720
Fiber is going to be paramount in kind of like
90
00:04:45.800 --> 00:04:48.600
setting your set point of your gut microbiome the rest
91
00:04:48.639 --> 00:04:52.240
of your life. There is prebiotic fiber, which you could
92
00:04:52.240 --> 00:04:55.560
think of as fish food for your good gut microbiome.
93
00:04:55.639 --> 00:04:58.000
Your gut microbiome is kind of like an aquairument or
94
00:04:58.000 --> 00:05:00.560
a fish tank. Any fiber or food that you're putting
95
00:05:00.600 --> 00:05:03.079
in your gut, it's either going to it's going to
96
00:05:03.120 --> 00:05:06.480
skew your gut microbiome towards something that is more beneficial
97
00:05:07.000 --> 00:05:08.079
or more detrimental.
98
00:05:08.399 --> 00:05:12.079
And would you say that the prebiotic fiber and getting
99
00:05:12.160 --> 00:05:15.639
essential fatty acids that would be important to do throughout
100
00:05:15.639 --> 00:05:17.199
the life span or just for the people in their
101
00:05:17.199 --> 00:05:17.759
twenties and.
102
00:05:17.680 --> 00:05:22.360
Thirties throughout the lifespan, particularly important in the teenage, twenties
103
00:05:22.399 --> 00:05:27.040
thirties because it helps with brain development. You're certainly more
104
00:05:27.079 --> 00:05:30.639
of an expert than me when it comes to brain development,
105
00:05:30.680 --> 00:05:34.240
but it does continue to develop really throughout the lifespan,
106
00:05:34.319 --> 00:05:36.279
but certainly through the twenties and thirties as well.
107
00:05:36.360 --> 00:05:38.759
In a previous discussion of ours, I asked you about
108
00:05:39.240 --> 00:05:42.759
caloric restriction and testosterone, and if I recall correctly, the
109
00:05:42.800 --> 00:05:45.279
idea was that if somebody is overweight, they have an
110
00:05:45.319 --> 00:05:48.600
excess fat at a post tissue, then getting rid of
111
00:05:48.600 --> 00:05:50.680
some of that at a post tissue but through chloric
112
00:05:50.759 --> 00:05:53.439
restriction and exercise, provided it's done not too fast in
113
00:05:53.439 --> 00:05:56.759
a healthy way, is going to be beneficial for testosterone
114
00:05:56.800 --> 00:06:00.439
in the long run. But that for individual who are
115
00:06:00.439 --> 00:06:03.040
not carrying an excess of body fat, caloric restriction is
116
00:06:03.079 --> 00:06:07.199
actually going to lower testosterone. First of all, do I
117
00:06:07.240 --> 00:06:11.160
have that correct? And second, are there any addendums to
118
00:06:11.199 --> 00:06:14.199
that that you'd like to give us? Now that's correct.
119
00:06:14.839 --> 00:06:18.720
If you look at an individual in a caloric deficit,
120
00:06:18.879 --> 00:06:22.439
several changes will happen. One is that they'll have less
121
00:06:22.480 --> 00:06:25.759
building blocks for hormones. Another is that they will be
122
00:06:25.800 --> 00:06:28.560
in a catabolic state more often, so that balance of
123
00:06:28.560 --> 00:06:32.639
anabolism and catabolism will be different. They'll likely have less
124
00:06:32.680 --> 00:06:36.759
signaling from growth hormone and IGF one, and they'll also
125
00:06:36.839 --> 00:06:39.680
have the high SHBG that we defined earlier as the
126
00:06:39.680 --> 00:06:43.639
binding protein, so they're free androgens and free estrogens will
127
00:06:43.680 --> 00:06:44.680
go down now.
128
00:06:44.680 --> 00:06:47.399
What are some of the other pillars of creating the
129
00:06:47.439 --> 00:06:49.360
proper environment for hormone optimization.
130
00:06:49.879 --> 00:06:55.600
Stress is probably the next one. During both puberty but
131
00:06:55.639 --> 00:07:00.120
also the twenties and thirties, individuals are figuring out how
132
00:07:00.160 --> 00:07:02.720
they want to cope with stress and also figuring out
133
00:07:02.759 --> 00:07:05.199
what they want to choose to put their effort into.
134
00:07:06.759 --> 00:07:09.560
So if someone is overstressed, then they can have it,
135
00:07:09.600 --> 00:07:13.199
can put all the other lifestyle pillars, and then they
136
00:07:13.199 --> 00:07:17.600
stop dieting, well, they stop exercising, and everything else can
137
00:07:17.639 --> 00:07:18.160
go askew.
138
00:07:18.519 --> 00:07:20.360
What would it be some of the additional things that
139
00:07:20.399 --> 00:07:21.279
everybody should do.
140
00:07:21.600 --> 00:07:24.920
Another one is finding what your purpose is in life.
141
00:07:25.360 --> 00:07:27.720
So I call this spirit, but it's really just the
142
00:07:27.800 --> 00:07:31.800
self actualization component of Maslow's hierarchy of needs, which is
143
00:07:31.839 --> 00:07:34.120
basically your physical needs, your mental needs, and then your
144
00:07:34.120 --> 00:07:36.399
purpose in life which you really like to do.
145
00:07:36.639 --> 00:07:39.439
The idea is not to pick the end goal, is
146
00:07:39.480 --> 00:07:42.759
to pick a goal and then once you reach that goal,
147
00:07:42.839 --> 00:07:45.680
to assess and then pick another goal and so on.
148
00:07:45.759 --> 00:07:47.680
I think sometimes when people hear about picking up purpose
149
00:07:47.680 --> 00:07:49.439
of like ohing goerness, I have to define sort of
150
00:07:49.439 --> 00:07:54.319
like naming oneself, that you actually can change your goals
151
00:07:54.319 --> 00:07:57.279
and purpose over time. I'd like to take a quick
152
00:07:57.279 --> 00:08:00.439
break and acknowledge one of our sponsors, Element Element is
153
00:08:00.439 --> 00:08:02.959
an electrolyte drink that has everything you need and nothing
154
00:08:03.000 --> 00:08:06.800
you don't. That means the electrolytes sodium, magnesium, and potassium
155
00:08:06.800 --> 00:08:09.680
in the correct amounts, but no sugar. Proper hydration is
156
00:08:09.680 --> 00:08:13.079
critical for optimal brain and body function. Even a slight
157
00:08:13.120 --> 00:08:16.959
degree of dehydration can diminish cognitive and physical performance. It's
158
00:08:17.000 --> 00:08:20.399
also important that you get adequate electrolytes. The electrolytes sodium,
159
00:08:20.399 --> 00:08:23.560
magnesium and potassium are vital for functioning of all the
160
00:08:23.560 --> 00:08:26.720
cells in your body, especially your neurons or your nerve cells.
161
00:08:27.120 --> 00:08:29.519
Drinking Element disolved in water makes it very easy to
162
00:08:29.600 --> 00:08:33.320
ensure that you're getting adequate hydration and adequate electrolytes. To
163
00:08:33.360 --> 00:08:36.320
make sure that I'm getting proper amounts of hydration and electrolytes,
164
00:08:36.600 --> 00:08:39.000
I dissolve one packet of Element in about sixteen to
165
00:08:39.039 --> 00:08:40.960
thirty two ounces of water when I first wake up
166
00:08:40.960 --> 00:08:43.279
in the morning, and I drink that basically first thing
167
00:08:43.320 --> 00:08:45.840
in the morning. I'll also drink Element dissolved in water
168
00:08:45.919 --> 00:08:48.799
during any kind of physical exercise that I'm doing, especially
169
00:08:48.840 --> 00:08:50.799
on hot days when I'm sweating a lot and losing
170
00:08:50.840 --> 00:08:54.480
water and electrolytes. Element has a bunch of great tasting flavors.
171
00:08:54.799 --> 00:08:57.399
I love the raspberry, I love the citrus flavor. Right now,
172
00:08:57.440 --> 00:09:01.440
Element has a limited addition lemonade flavor is absolutely delicious.
173
00:09:01.519 --> 00:09:03.200
I hate to say that I love one more than
174
00:09:03.240 --> 00:09:05.759
all the others, but this lemonade flavor is right up
175
00:09:05.799 --> 00:09:09.159
there with my favorite other one, which is raspberry or watermelon. Again,
176
00:09:09.200 --> 00:09:11.240
I can't pick just one flavor. I love them all.
177
00:09:11.639 --> 00:09:13.440

00:09:27.159 --> 00:09:31.320

183
00:09:31.320 --> 00:09:33.519
that people should do, or I should say the key
184
00:09:33.559 --> 00:09:35.840
things that men should do to optimize their hormones. What
185
00:09:35.840 --> 00:09:40.240
do you think is a healthy, sustainable exercise regimen that
186
00:09:40.960 --> 00:09:44.919
anyone can follow that will also support their hormone status.
187
00:09:45.320 --> 00:09:49.039
For really vigorous exercise around three to four times a
188
00:09:49.080 --> 00:09:51.919
week is very sustainable over a long period of time.
189
00:09:52.639 --> 00:09:54.519
On top of that, you could add in three or
190
00:09:54.559 --> 00:09:59.519
four more instances of less vigorous exercise. When they study
191
00:09:59.759 --> 00:10:04.759
the effect of exercise, specifically vigorous exercise, one area that's
192
00:10:04.799 --> 00:10:09.240
been studied is vigorous exercise episodes lasting longer than an hour,
193
00:10:10.080 --> 00:10:13.720
and they usually track it by a rating of perceived exertion,
194
00:10:13.799 --> 00:10:16.879
which isn't perfect and it's not extremely actionable, but it's
195
00:10:16.879 --> 00:10:20.279
helpful for clinical science. But the takeaway from that is basically,
196
00:10:20.919 --> 00:10:27.600
do not. It is not hormonally helpful to train, especially regularly,
197
00:10:27.639 --> 00:10:30.960
train vigorously for longer than an hour.
198
00:10:31.480 --> 00:10:34.960
These days, for better or for worse, I think for worse,
199
00:10:36.120 --> 00:10:41.919
younger guys are asking about and using testosterone replacement therapy
200
00:10:41.960 --> 00:10:46.759
so called TRT. Why in the world would any male
201
00:10:47.159 --> 00:10:52.559
in his teens or twenties or even thirties, whose blood
202
00:10:52.639 --> 00:10:55.799
levels of testosterone and estrogen are at the appropriate levels,
203
00:10:55.879 --> 00:10:59.399
meaning within the normal reference range, why would they take
204
00:10:59.519 --> 00:11:05.080
exogic testosterone Given all the negative effects on fertility, some
205
00:11:05.120 --> 00:11:07.200
of the challenges that it can present, if the dosages
206
00:11:07.200 --> 00:11:10.799
aren't quite right, et cetera, why would they do that? Certainly,
207
00:11:11.080 --> 00:11:15.039
if they are not being paid for a particular endeavor,
208
00:11:15.080 --> 00:11:17.159
like they're not making money. If they are playing as sports,
209
00:11:17.240 --> 00:11:19.039
chances are they're not allowed to do that anyway. It's
210
00:11:19.759 --> 00:11:22.039
on the banned substances list. So to me it just
211
00:11:22.080 --> 00:11:25.840
seems like a crazy idea. But then again, I'm of
212
00:11:25.879 --> 00:11:28.799
a generation that really hasn't thought about doing that stuff
213
00:11:28.879 --> 00:11:32.000
until people were in their forties and fifties or even never.
214
00:11:32.840 --> 00:11:35.440
So is there ever a case for somebody in their
215
00:11:35.519 --> 00:11:39.200
twenties or thirties to take testosterone but if their blood
216
00:11:39.279 --> 00:11:43.039
levels are within the three hundred to nine hundred nanograms
217
00:11:43.039 --> 00:11:44.480
per DESO leader reference range.
218
00:11:44.639 --> 00:11:48.039
You know, everyone has their different reason as far as
219
00:11:48.120 --> 00:11:52.559
like when does the benefit outweigh the detriment? Not very
220
00:11:52.639 --> 00:11:56.919
often if you're in your twenties, and certainly probably almost
221
00:11:56.960 --> 00:11:59.639
hardly never. There's always, you know, rare cases like Coleman
222
00:11:59.679 --> 00:12:04.519
syndrome and whatnot, but almost never if you're very young.
223
00:12:04.919 --> 00:12:07.960
Okay, So for people in their twenties, thirties and beyond forties,
224
00:12:07.960 --> 00:12:11.759
et cetera, whose testosterone and estrogen levels are at the
225
00:12:11.759 --> 00:12:16.720
appropriate ratios and in within the normal reference range libido
226
00:12:16.840 --> 00:12:22.879
energy recovery, et cetera, are feeling least workable for their lifestyle.
227
00:12:23.639 --> 00:12:28.039
For those people, what can they do besides get great sleep,
228
00:12:28.639 --> 00:12:30.519
train but not too hard or too often, et cetera,
229
00:12:30.559 --> 00:12:32.320
et cetera. What are some of the things in the
230
00:12:32.360 --> 00:12:36.720
realm of supplementation that can help them optimize their testosterone
231
00:12:36.720 --> 00:12:42.000
and estrogen without suppressing their own indogenous production of testosterone
232
00:12:42.039 --> 00:12:42.600
and estrogen.
233
00:12:43.240 --> 00:12:46.840
Let's mention. Creatine is the first one. Creatine is interesting
234
00:12:46.879 --> 00:12:49.480
because it has multiple different effects. That helps with amino
235
00:12:49.519 --> 00:12:53.679
acid synthesis. It also helps with oxidative stress. It can
236
00:12:53.720 --> 00:12:56.679
also serve as the backup fuel tank for your monochondria,
237
00:12:56.759 --> 00:13:00.519
so kind of holding backup atp and it does slightly
238
00:13:00.600 --> 00:13:04.279
increase total testosterone and it also increases the conversion of
239
00:13:04.279 --> 00:13:08.840
testosterone to die hydro testosterone, so potentially it's especially useful
240
00:13:09.080 --> 00:13:13.519
in men in their even their teenage years and their twenties.
241
00:13:14.080 --> 00:13:17.240
You mentioned the conversion of testosterone to dihydrag testosterone, and
242
00:13:17.279 --> 00:13:20.559
there is mythology out there that creatine can increase hair loss.
243
00:13:20.559 --> 00:13:23.120
I'm guessing because there's at least one study showing that
244
00:13:23.120 --> 00:13:27.840
creatine can increase DHD dihydrad testosterone, and DHD is one
245
00:13:27.879 --> 00:13:31.440
of the primary hormones that can promote mail pattern baldness.
246
00:13:32.240 --> 00:13:38.159
So the question therefore is does create creatine supplementation increase
247
00:13:38.240 --> 00:13:39.120
the rate of hair.
248
00:13:38.960 --> 00:13:44.639
Loss in each individual? Preventing hair loss is a very
249
00:13:44.679 --> 00:13:47.360
poor reason to creatine because it's not going to take
250
00:13:47.399 --> 00:13:52.559
you to a supra physiologic level. It's not going to
251
00:13:52.679 --> 00:13:58.679
increase your androgens to an unnormal level of binding. So
252
00:13:58.759 --> 00:14:02.080
I feel like this, if that was a reason to
253
00:14:02.159 --> 00:14:04.639
not take creatine for hair loss, then.
254
00:14:04.639 --> 00:14:06.840
That means sorry, you mean hair loss is not a
255
00:14:06.879 --> 00:14:09.080
reason to avoid taking creatine.
256
00:14:09.080 --> 00:14:12.399
Correct hair loss is not a reason to avoid taking creatine.
257
00:14:13.360 --> 00:14:16.440
Think of it as just bringing you to what you
258
00:14:16.559 --> 00:14:21.360
are naturally inclined to have. If your conversion of testosterone
259
00:14:21.399 --> 00:14:24.759
to DHD is already high, then often creatine does not
260
00:14:24.919 --> 00:14:28.879
affect this. It just kind of resets your balance between
261
00:14:28.919 --> 00:14:33.919
testosterone being aromatized to estrogen or being five alpha reduced DHD.
262
00:14:34.759 --> 00:14:36.679
So it's not going to speed up hair loss more
263
00:14:36.720 --> 00:14:40.799
than just naturally being a male does. So in some individuals,
264
00:14:40.879 --> 00:14:44.600
it will have no effect. In some individuals for whatever reason,
265
00:14:44.639 --> 00:14:47.679
they have almost no five alpha reductase activity. It will
266
00:14:47.720 --> 00:14:49.399
return them to natural or normal.
267
00:14:49.840 --> 00:14:53.639
So what other supplement based tools. Can people consider.
268
00:14:53.679 --> 00:14:56.120
Another one we can loop in with creatine is beta en.
269
00:14:56.519 --> 00:14:59.799
Some people are non responders to creatines. You can increase
270
00:14:59.799 --> 00:15:02.600
that to ten grams, or you can use its cousin
271
00:15:02.679 --> 00:15:06.519
beta en to help with amino acid synthesis and shunting
272
00:15:06.559 --> 00:15:10.000
of energy. Along with that, I would put L carnatine
273
00:15:10.399 --> 00:15:11.000
beta en.
274
00:15:11.559 --> 00:15:15.840
Do you recall what dosage people typically would take if
275
00:15:15.840 --> 00:15:18.559
they're a creating non responder.
276
00:15:18.240 --> 00:15:21.440
One to three grams in fact, So yeah, several versions
277
00:15:21.480 --> 00:15:24.559
of creating have beta en mixed in because it helps
278
00:15:24.600 --> 00:15:27.320
with the processing of mathianine and homocysteine.
279
00:15:27.639 --> 00:15:30.320
So if somebody is already taking creatine and likes it
280
00:15:30.360 --> 00:15:33.080
and responds to it, will raise my hand such as myself.
281
00:15:33.279 --> 00:15:38.240
Would adding beta en help or is it redundant with creatine.
282
00:15:37.840 --> 00:15:41.360
Only if their homocystine is persistently elevated. And homocysteine is
283
00:15:41.399 --> 00:15:43.799
kind of like an inflammatory marker that can build up
284
00:15:43.919 --> 00:15:46.320
if you're not converting enough of it down the stream.
285
00:15:46.480 --> 00:15:50.240
How would I know just a blood test, so L carnatine,
286
00:15:50.720 --> 00:15:52.919
What are the ways to take L carnatine. I know
287
00:15:52.960 --> 00:15:55.879
that there's an oral form, so capsules, and there's injectibles,
288
00:15:55.919 --> 00:15:58.360
the injectibles, I think you need a prescription, Is that
289
00:15:58.440 --> 00:15:59.200
right correct?
290
00:15:59.240 --> 00:16:01.360
Do you need a prescript for the injectables or you
291
00:16:01.360 --> 00:16:05.159
should really get a prescription for the injectables. When you
292
00:16:05.200 --> 00:16:08.919
inject it, of course at the supervision of your doctor,
293
00:16:09.000 --> 00:16:12.960
it's usually done intramuscularly. It's an aqueous solution, so it
294
00:16:13.000 --> 00:16:15.000
does not have like an oil or a carrier oil
295
00:16:15.000 --> 00:16:19.519
in it like tr like testosterone esters do. However, if
296
00:16:19.559 --> 00:16:22.559
you inject it to superficially, it's not going to make
297
00:16:22.559 --> 00:16:24.919
a break anything. Often it just burns if you inject
298
00:16:24.960 --> 00:16:29.080
it subcutaneously, and it does not disseminate throughout the body
299
00:16:29.120 --> 00:16:34.240
as well. L carnatine potentially has localized effects if you
300
00:16:34.320 --> 00:16:38.039
inject it, if you ingest it orally, then it has
301
00:16:38.039 --> 00:16:40.879
a very low bioavailability, maybe only ten percent.
302
00:16:41.399 --> 00:16:43.399
So what are the dosages of L carnantine that one
303
00:16:43.440 --> 00:16:46.279
needs to ingest then if they want to get a benefit.
304
00:16:46.360 --> 00:16:50.159
Because I find only ten percent is being absorbed, it's
305
00:16:50.159 --> 00:16:52.360
probably a lot of L carnantine? How much should people
306
00:16:52.360 --> 00:16:52.960
take per day?
307
00:16:53.320 --> 00:16:57.080
Usually I recommend for oral L carnatine between one thousand
308
00:16:57.080 --> 00:17:01.120
milligrams and up to four or five thousand millis so.
309
00:17:01.120 --> 00:17:04.720
Onond to four maybe even five grams.
310
00:17:03.960 --> 00:17:06.680
Correct up to five grams a day. If you're on
311
00:17:06.799 --> 00:17:10.680
that much, especially if you have a dysregulated gut microbiome,
312
00:17:11.160 --> 00:17:14.039
you should be concerned with TMAO, which is a potential
313
00:17:14.079 --> 00:17:18.519
carcinogen that both carnatine and coline can convert into, and
314
00:17:18.559 --> 00:17:21.960
your gut microbiota determine how much that happens.
315
00:17:22.079 --> 00:17:24.440
Is it true that I can offset any negative effects
316
00:17:24.440 --> 00:17:29.279
of alpha gpc coline, that is NL carnatine that I
317
00:17:29.319 --> 00:17:31.799
take by ingesting garlic? Is that right?
318
00:17:31.920 --> 00:17:34.960
There's a compound in garlic called alison. I believe it's
319
00:17:35.000 --> 00:17:37.519
a l I ci in. It's also part of the
320
00:17:37.559 --> 00:17:42.319
scientific name the genus of types of garlic, and this
321
00:17:42.400 --> 00:17:45.839
can help decrease the conversion to TMAO. Berberine actually slightly
322
00:17:45.880 --> 00:17:49.920
decreases the conversion to TMO as well, probably through alteration
323
00:17:49.960 --> 00:17:53.319
of the gut microbiome, and then just optimizing your gut
324
00:17:53.319 --> 00:17:57.119
microbiome can decrease conversion. So not everyone needs allison, but
325
00:17:57.160 --> 00:17:59.440
it's something that you should certainly consider if you were
326
00:17:59.480 --> 00:17:59.880
on a hip.
327
00:18:01.160 --> 00:18:04.119
I'm going to continue to take the six hundred milligrams
328
00:18:04.319 --> 00:18:06.640
of gar like every time I take my L carnatine,
329
00:18:06.640 --> 00:18:08.759
But I'm going to skip the berberene because berberine gives
330
00:18:08.799 --> 00:18:11.400
me brutal headaches, and it makes me create carbohydrates because
331
00:18:11.440 --> 00:18:12.559
it drops my blood sugar.
332
00:18:12.640 --> 00:18:15.640
It has many other effects, including the dawn phenomenon where
333
00:18:15.640 --> 00:18:17.519
it drops your blood sugar when you're sleeping and you
334
00:18:17.519 --> 00:18:18.559
can't even realize it.
335
00:18:18.599 --> 00:18:21.160
Okay, And what we did not talk about is what
336
00:18:21.279 --> 00:18:22.240
L carnatine does.
337
00:18:22.799 --> 00:18:26.640
It's a shuttle, so I think it's named carnatine palmetell
338
00:18:26.960 --> 00:18:31.400
coenzyme A. Basically, it's it just takes nutrients from outside
339
00:18:31.440 --> 00:18:34.359
your mitochondria and puts them in. It also has a
340
00:18:34.480 --> 00:18:37.720
unique effect, well not too unique because tadalophil actually has
341
00:18:37.720 --> 00:18:41.000
this effect as well, is that it increases the density
342
00:18:41.160 --> 00:18:44.519
of the androgen receptor and the cytoplasm of your cells.
343
00:18:45.359 --> 00:18:48.599
So even if your androgen receptor sensitivity doesn't change, and
344
00:18:48.680 --> 00:18:51.799
even if you doesn't testosterone does not change, you will
345
00:18:51.839 --> 00:18:55.279
have more testosterone binding to that increased number of receptors.
346
00:18:55.599 --> 00:18:59.039
Does one need to cycle L carnatine, creatine.
347
00:18:58.519 --> 00:19:01.480
Beta ene into cycle any of those?
348
00:19:01.759 --> 00:19:05.000
What other supplements can one use to try and improve
349
00:19:05.319 --> 00:19:08.599
hormone profiles. And here I realize we're using a very
350
00:19:08.599 --> 00:19:11.000
broad brush because when we say improve hormone profiles, what
351
00:19:11.039 --> 00:19:14.279
are we really talking about? And for me, at least,
352
00:19:14.279 --> 00:19:18.680
I think about the subjective stuff. You know, do people
353
00:19:18.839 --> 00:19:20.759
feel like they are going to have more energy as
354
00:19:20.759 --> 00:19:22.920
a consequence of doing these things? Are they going to
355
00:19:23.000 --> 00:19:25.759
have the more optimized libido? Are they going to have
356
00:19:25.920 --> 00:19:28.680
more optimized recovery from exercise?
357
00:19:28.759 --> 00:19:28.880
Right?
358
00:19:28.920 --> 00:19:31.039
Because I mean, it's not clear to me that taking
359
00:19:31.160 --> 00:19:33.559
one's testosteron from six hundred to eight hundred is always
360
00:19:33.599 --> 00:19:35.960
going to be a good thing, especially if estrogen is
361
00:19:36.000 --> 00:19:39.480
increasing in parallel. That could cause issues. It could certainly
362
00:19:39.480 --> 00:19:41.279
make things better, it could certainly make things worse.
363
00:19:41.519 --> 00:19:44.839
Right, Let's briefly mention vitamin D, which is also a hormone.
364
00:19:44.880 --> 00:19:48.200
It's actually a sterile hormone and have. If you have
365
00:19:48.319 --> 00:19:51.039
deficient vitamin D and you replace it, then you will
366
00:19:51.079 --> 00:19:55.119
optimize your testosterone. It's also mentioned boron, so if you
367
00:19:55.119 --> 00:19:58.680
have a very high SHBG, boron can acutely help lower it,
368
00:19:58.799 --> 00:20:01.680
usually in a dose of five to twelve milligrams per day.
369
00:20:02.160 --> 00:20:06.079
It's not really a sustained effect, but boron is depleted
370
00:20:06.079 --> 00:20:08.839
in soils in many countries. I believe it's very high
371
00:20:08.839 --> 00:20:11.599
in soils in Grease and Turkey, so eating dates or
372
00:20:11.640 --> 00:20:14.519
raisins that are from those areas potentially have more boron.
373
00:20:15.000 --> 00:20:18.160
Boron also might be one of the reasons why the
374
00:20:18.200 --> 00:20:22.519
reference range for testosterone is much higher in those countries
375
00:20:22.880 --> 00:20:23.759
than other countries.
376
00:20:23.920 --> 00:20:26.839
And just to remind people, the SHPG sex hormone mining
377
00:20:26.839 --> 00:20:30.200
globulin is attaching to the diesosterone molecule and limiting the
378
00:20:30.200 --> 00:20:32.720
amount of so called free testosterone that's available to have
379
00:20:32.759 --> 00:20:35.799
its impact on cells. Okay, so, vitamin D three, I'm
380
00:20:35.839 --> 00:20:38.160
guessing you're talking about vitamin D three specifically when you
381
00:20:38.160 --> 00:20:41.000
say vitamin D and then boron five to twelve milligrams
382
00:20:41.039 --> 00:20:43.839
per day, right, and then what are some of the
383
00:20:43.839 --> 00:20:47.720
other things to optimize testosterone that are in supplement form.
384
00:20:48.200 --> 00:20:51.240
We can talk about things that affect the steroidogenesis cascades,
385
00:20:51.279 --> 00:20:53.039
So we could touch on ton cat ali. I know
386
00:20:53.079 --> 00:20:54.920
we've talked about that a little bit before, and.
387
00:20:54.920 --> 00:20:57.759
I'm guessing a number of people probably haven't heard that conversation.
388
00:20:58.119 --> 00:21:01.960
Also known as long jack and net upregulates several different
389
00:21:02.240 --> 00:21:06.680
enzymes in this steroidogenesis cascade and by that what you
390
00:21:06.720 --> 00:21:09.039
mean if and this is another good thing to google.
391
00:21:09.079 --> 00:21:12.200
I think anybody interested in a hormone optimization should understand
392
00:21:12.799 --> 00:21:16.920
where sterol hormones come from. They come usually from cholesterol,
393
00:21:17.319 --> 00:21:19.839
and they can be shunted off to vitamin D very easily.
394
00:21:20.160 --> 00:21:23.640
They can be shunted off to testosterone or estrogens or
395
00:21:23.680 --> 00:21:28.079
progestogens quite easily as well. But tonkat helps with the
396
00:21:28.200 --> 00:21:35.200
conversion of multiple key steps where you synthesize testosterone another
397
00:21:36.640 --> 00:21:39.000
I think of it as like a coenzyme or a cofactor.
398
00:21:39.000 --> 00:21:42.799
An upregulator of these steps is insulin and IGF one.
399
00:21:43.759 --> 00:21:46.359
So a good rule of thumb is if you are
400
00:21:46.480 --> 00:21:49.680
not expecting as much growth hormone insulin and IGF one,
401
00:21:50.039 --> 00:21:54.519
for example, lower carb diets, caloric deficits, you're trying to
402
00:21:54.559 --> 00:21:57.880
cut body fat or body weight, then tonkat is going
403
00:21:57.960 --> 00:22:01.200
to be theoretically specially powerful.
404
00:22:02.160 --> 00:22:04.759
What sorts of dosages of tongua do you recommend to
405
00:22:04.759 --> 00:22:07.000
your patients anywhere.
406
00:22:06.559 --> 00:22:11.079
From three hundred to twelve hundred milligrams a day with tonkat,
407
00:22:11.200 --> 00:22:16.000
you need to be careful with the standardization because if
408
00:22:16.039 --> 00:22:18.599
you're thinking about a general tonkat supplement, which is by
409
00:22:18.640 --> 00:22:23.240
far the most well studied. Then you're looking at the
410
00:22:23.599 --> 00:22:27.759
uryicominone content, which is a plant compound that is likely
411
00:22:27.839 --> 00:22:32.559
the main active pharmacologic effect. So that's the compound that's
412
00:22:32.599 --> 00:22:35.839
having the effect on the body. And if you standardize
413
00:22:35.880 --> 00:22:40.559
the uryicominone very very high, then theoretically you're having more
414
00:22:40.599 --> 00:22:41.920
effect at a lower dose.
415
00:22:42.440 --> 00:22:44.720
My blood work tells me that it causes an increase
416
00:22:44.720 --> 00:22:48.000
in free testosterone for me and also a slight increase
417
00:22:48.039 --> 00:22:51.160
in lutinizing hormone for me. What are some of the
418
00:22:51.200 --> 00:22:54.160
other effects on various hormones that you've observed in the
419
00:22:54.160 --> 00:22:55.359
blood work of your patients?
420
00:22:55.400 --> 00:23:00.319
Taking tongua ali tongkat can also slightly increase DHA And
421
00:23:00.960 --> 00:23:03.640
if you have a very high SHBG. Again, that's the
422
00:23:03.680 --> 00:23:07.160
protein that binds up your androgens, and estrogen's an extremely
423
00:23:07.200 --> 00:23:11.799
important protein. The higher your SHBG, the more it helps
424
00:23:11.839 --> 00:23:16.920
decrease it. So they've studied tongkat in populations with very
425
00:23:17.000 --> 00:23:19.839
normal shbgs and it does nothing for SHBG.
426
00:23:20.319 --> 00:23:23.279
Interesting, does that mean it does nothing for somebody overall?
427
00:23:23.400 --> 00:23:26.200
So if somebody has SHBG that's in the normal range,
428
00:23:26.359 --> 00:23:28.920
will taking tonguat benefit them in any other way.
429
00:23:29.559 --> 00:23:33.319
Yes, it'll increase their total and free testosterone.
430
00:23:33.480 --> 00:23:35.920
I'd like to take a quick break and acknowledge our sponsor,
431
00:23:36.200 --> 00:23:39.880
ag One. Ag One is a vitamin, mineral probiotic drink
432
00:23:39.920 --> 00:23:44.200
that also includes prebiotics and adaptogens. I discovered ag one
433
00:23:44.279 --> 00:23:47.079
way back in twenty twelve, long before I ever had
434
00:23:47.079 --> 00:23:49.440
a podcast, and I've been taking it every day since.
435
00:23:49.720 --> 00:23:51.960
The reason I started taking ag one and the reason
436
00:23:51.960 --> 00:23:54.559
I still take it every day is because ag one is,
437
00:23:54.559 --> 00:23:57.640
to my knowledge, the highest quality and most comprehensive of
438
00:23:57.680 --> 00:24:00.960
the foundational nutritional supplements on the market. Ag One is
439
00:24:01.000 --> 00:24:03.799
designed to support things like gut health, immune health, and
440
00:24:03.880 --> 00:24:06.440
overall energy, and it does so by helping to fill
441
00:24:06.480 --> 00:24:08.720
any gaps that you might have in your daily nutrition.
442
00:24:09.119 --> 00:24:11.359
I get asked pretty much all the time if I
443
00:24:11.359 --> 00:24:13.640
could only take one supplement, what should that supplement be?
444
00:24:14.000 --> 00:24:16.640
And my answer is always ag one. It has just
445
00:24:16.720 --> 00:24:20.079
been so helpful for supporting all aspects of physical health,
446
00:24:20.160 --> 00:24:22.680
mental health, and performance. If you would like to try
447
00:24:22.720 --> 00:24:25.759
ag one, you can go to drinkag one dot com

457
00:24:54.559 --> 00:24:58.119
that you prescribe to your patients who do not want
458
00:24:58.160 --> 00:25:02.240
to go on testosterone replacement therapy or take exogenous DHA
459
00:25:02.440 --> 00:25:03.319
or anything like that.
460
00:25:03.680 --> 00:25:07.359
We could talk about Fidosian next. Fidosia's interesting because it's
461
00:25:07.400 --> 00:25:10.319
a genus of plants. Fidosia agrestis is one of them.
462
00:25:10.359 --> 00:25:14.599
There's many others that are very interesting. That species is
463
00:25:14.839 --> 00:25:18.039
likely the most well studied. And it will increase LH,
464
00:25:18.519 --> 00:25:21.880
so I would not consider it an LH mimetic, so
465
00:25:21.920 --> 00:25:24.599
it doesn't really mimic it, but it increases the release
466
00:25:24.640 --> 00:25:27.240
of lutinizing a hormone from the pituitary that's a hormone
467
00:25:27.240 --> 00:25:30.880
that binds to the LATEG cell, to the LT receptor,
468
00:25:30.960 --> 00:25:34.680
kind of like HGG does, and it will increase the
469
00:25:34.799 --> 00:25:36.200
release of testosterone.
470
00:25:36.400 --> 00:25:39.880
What dosages do you have patient's stake. I've heard of
471
00:25:40.480 --> 00:25:43.599
some potential toxicity to the testicular cells.
472
00:25:43.799 --> 00:25:46.119
There is one study, and this is a rat study,
473
00:25:46.200 --> 00:25:49.599
but you can equate the dose of toxicity in rats
474
00:25:49.640 --> 00:25:52.680
in humans. They did not give these rats any antioxidants.
475
00:25:53.160 --> 00:25:58.079
But it increases a couple different like pro inflammatory markers.
476
00:25:58.119 --> 00:26:01.880
One is GGT or gamma gluten transferrace comes from both
477
00:26:01.920 --> 00:26:04.839
the testes and the liver, and one is alkaline phosphatase
478
00:26:05.079 --> 00:26:08.480
also known as alk FOSS, again coming from both areas.
479
00:26:08.880 --> 00:26:11.680
There are several different ways that you can attenuate this increase,
480
00:26:11.720 --> 00:26:13.400
and you can also just check to see if you
481
00:26:13.440 --> 00:26:17.519
have increased in the rat dose that equates with humans
482
00:26:17.519 --> 00:26:20.519
that had no effect. So the safe dose was an
483
00:26:20.599 --> 00:26:23.079
average of three hundred milligrams a day.
484
00:26:22.960 --> 00:26:25.599
So that would be three hundred milligrams a day in humans.
485
00:26:26.240 --> 00:26:28.920
Is the dosage that did not have toxicity.
486
00:26:29.039 --> 00:26:33.880
Correct correct, And often even if there is toxicity in rats,
487
00:26:33.960 --> 00:26:37.039
there is not toxicity humans, so it's not directly equitable,
488
00:26:37.559 --> 00:26:41.240
but to be safe, another regimen that I have people
489
00:26:41.240 --> 00:26:44.039
take is six hundred milligrams every other day or six
490
00:26:44.160 --> 00:26:47.799
hundred milligrams three times a week, often Monday, Wednesday, Friday.
491
00:26:48.279 --> 00:26:50.680
My understanding is that nowadays a lot of people are
492
00:26:50.759 --> 00:26:53.799
using testosterone. Let's not even call it replacement therapy, because
493
00:26:53.799 --> 00:26:56.480
some of these people have six hundred, seven hundred or
494
00:26:56.519 --> 00:26:59.200
even you know, eight hundred nine a gram peresile to read,
495
00:26:59.279 --> 00:27:02.599
So not replacing anything that is diminished. They're just trying
496
00:27:02.640 --> 00:27:05.599
to augment what's already there, increase what's already there. My
497
00:27:05.720 --> 00:27:09.240
understanding is that taking a low dose more frequently is
498
00:27:09.279 --> 00:27:11.680
going to be more beneficial than the kind of old
499
00:27:11.680 --> 00:27:14.119
school way of giving you know, one hundred or even
500
00:27:14.119 --> 00:27:17.160
two hundred milligrams in a single injection once every two weeks.
501
00:27:17.400 --> 00:27:19.480
Is that right? And what do you do with your patients?
502
00:27:19.599 --> 00:27:21.599
So let me give you a hypothetical. Somebody comes into
503
00:27:21.599 --> 00:27:26.680
your office. There their blood work and they have blood
504
00:27:26.720 --> 00:27:30.599
levels of let's say, six hundred anagrams per deestly or estosterone.
505
00:27:30.640 --> 00:27:34.319
Their estrogen is also in normal range. Everything else checks out,
506
00:27:34.640 --> 00:27:38.359
but they're complaining of you know, slightly diminished libido, slightly
507
00:27:38.400 --> 00:27:43.079
poor recovery from workouts, maybe you know, reduce motivation and drive,
508
00:27:43.119 --> 00:27:46.160
although no major depression. And you come to the conclusion
509
00:27:46.160 --> 00:27:50.279
that testosterone therapy. Not replacement, but testosterone therapy might be
510
00:27:50.279 --> 00:27:53.880
a good option to explore. What's a typical dosage range
511
00:27:54.119 --> 00:27:58.559
and frequency of administration range that you might consider exploring.
512
00:27:59.119 --> 00:28:02.200
Some of this depends on SHBG and free testosterone as well.
513
00:28:02.240 --> 00:28:05.039
So if that same individual had a very high SHBG,
514
00:28:05.079 --> 00:28:07.240
which again is the binding protein that binds up the
515
00:28:07.279 --> 00:28:11.000
testosterone and all androgens and estrogens, if it is extremely
516
00:28:11.079 --> 00:28:15.000
high and they have a free testosterone of two, then
517
00:28:15.000 --> 00:28:17.440
they might need a different dose because they need enough
518
00:28:17.480 --> 00:28:23.880
testosterone in order to have a normal uganadol free testosterone.
519
00:28:24.319 --> 00:28:27.799
But a general normal dosing range, especially for someone starting,
520
00:28:27.880 --> 00:28:31.000
is around one hundred to one hundred and twenty milligrams
521
00:28:31.319 --> 00:28:34.880
divided over the course of a week, usually either every
522
00:28:34.960 --> 00:28:38.160
other day or three times a week, occasionally twice a week.
523
00:28:38.680 --> 00:28:41.839
Many people with SHBG a bit higher can get away
524
00:28:41.880 --> 00:28:44.759
pretty easily with twice a week. This is assuming that
525
00:28:44.759 --> 00:28:47.200
the ester is sipienate or a nantheate.
526
00:28:46.920 --> 00:28:51.680
So two sixty milligram injections of testosteronecipientate.
527
00:28:50.759 --> 00:28:52.799
Per week, yeah, very common dosing to.
528
00:28:52.839 --> 00:28:54.799
Hit that one hundred and twenty milligrams per week as
529
00:28:54.880 --> 00:28:56.559
kind of the typical average.
530
00:28:56.160 --> 00:28:59.839
Erect and I would consider this like a physiologic yugan adult.
531
00:29:00.680 --> 00:29:04.000
For many people, even two hundred milligrams a week is
532
00:29:04.519 --> 00:29:07.200
far above the reference range. All of this is said
533
00:29:07.200 --> 00:29:10.839
with the caveat that testosterone is normally released in a
534
00:29:10.920 --> 00:29:13.400
pulsatile manner, so it's high in the morning, low in
535
00:29:13.400 --> 00:29:19.480
the evening. Whereas if you're on testosterone therapy, then you're
536
00:29:19.519 --> 00:29:22.359
going to have a steady state, so your testosterone level
537
00:29:22.400 --> 00:29:24.599
is going to be pretty much the same even in
538
00:29:24.640 --> 00:29:25.119
the evening.
539
00:29:25.480 --> 00:29:28.200
In your experience, when patients do that, they I'm guessing
540
00:29:28.240 --> 00:29:31.039
they report the normal constellation of positive effects, you know,
541
00:29:31.079 --> 00:29:35.400
improved mood, improved energy, improved sleep, recovery, et cetera. What
542
00:29:35.440 --> 00:29:38.400
are some of the hazards or things that can crop
543
00:29:38.519 --> 00:29:41.920
up in blood work or just subjectively that can be
544
00:29:41.960 --> 00:29:44.119
warning signs that even a dosage of one hundred and
545
00:29:44.119 --> 00:29:46.920
twenty milligrams divided into these two or three dosages per
546
00:29:46.920 --> 00:29:48.119
week is too high.
547
00:29:48.279 --> 00:29:51.440
So this is when you really have to be at
548
00:29:51.519 --> 00:29:55.559
least well versed in every organ system, not just the
549
00:29:55.880 --> 00:30:00.359
ganadal like you know, genital system you need do have
550
00:30:01.200 --> 00:30:06.440
you know, dermatology, prowess. Acne is very common change lots
551
00:30:06.480 --> 00:30:10.000
of different skin pathologies or even bruising can be related
552
00:30:10.000 --> 00:30:13.519
to hormone replacement. Hair Loss is very common to see
553
00:30:13.519 --> 00:30:17.880
as well mental status changes. It could occasionally it even
554
00:30:17.880 --> 00:30:21.200
induces a manic or a bipolar episode because testosterone is
555
00:30:21.240 --> 00:30:25.799
also dopaminergic, and then cardiovascularly, not just in the heart,
556
00:30:25.960 --> 00:30:30.079
but also concerns for like microvascular a schemic disease, ferret
557
00:30:30.200 --> 00:30:33.640
and build up because the estrogen also increases, and then
558
00:30:34.079 --> 00:30:37.880
fertility concerns as well, and lipid concerns too, So you
559
00:30:37.920 --> 00:30:44.240
really have to be you know, hematologist, dermatologist, cardiologists, lipidologists,
560
00:30:44.279 --> 00:30:45.200
the whole nine yards.
561
00:30:45.599 --> 00:30:51.039
So another reason or set of reasons rather to if
562
00:30:51.079 --> 00:30:54.079
one is considering using testosterone therapy to really do this
563
00:30:54.319 --> 00:30:57.960
in close communication with a really good physician, because that's
564
00:30:58.000 --> 00:30:59.519
a lot to monitor. Knowing whether or not you have
565
00:30:59.519 --> 00:31:01.759
acting or not is one thing, but knowing whether or
566
00:31:01.799 --> 00:31:04.119
not your LDL is going up, your ABOB is going up,
567
00:31:04.119 --> 00:31:05.839
that's a whole other biz. And that needs to be
568
00:31:05.880 --> 00:31:07.759
done through blood work, is what I'm hearing.
569
00:31:08.119 --> 00:31:11.839
Correct And if your physician that is managing or prescribing
570
00:31:11.920 --> 00:31:17.079
your testosterone therapy or your HRT is not well versed
571
00:31:17.079 --> 00:31:19.279
in these systems. You would want him or her to
572
00:31:19.319 --> 00:31:21.920
be part of an interdisciplinary team where they have other
573
00:31:22.000 --> 00:31:24.160
experts that can monitor those systems.
574
00:31:24.440 --> 00:31:26.880
There are males out there who want to increase their
575
00:31:26.920 --> 00:31:31.640
testosterone and other hormones, maybe growth hormone, et cetera, who
576
00:31:31.839 --> 00:31:35.599
opt to not take exogenous testosterones, no cream, no pellet,
577
00:31:35.680 --> 00:31:40.519
no no pill, no injectable scipionate, but decide to take
578
00:31:40.720 --> 00:31:44.720
chlmophin a couple times a week. My understanding, I've never
579
00:31:44.720 --> 00:31:46.839
done this, I would say if I had. My understanding
580
00:31:46.920 --> 00:31:52.240
is that taking chlomophin maybe two fifty milligram tablets a week,
581
00:31:52.359 --> 00:31:55.079
is what I hear people are doing, will increase what
582
00:31:55.279 --> 00:32:00.519
lutinizing hormone, the various estrogen receptor subunits. Did you explain
583
00:32:00.559 --> 00:32:03.640
how chomophin would benefit anyone and is this a good strategy.
584
00:32:03.920 --> 00:32:06.039
I'm hearing that it's being done quite a lot now.
585
00:32:06.559 --> 00:32:09.839
It will increase testosterone in a dose to pendent manner,
586
00:32:10.359 --> 00:32:13.359
but it has many other pharmacodynamic effects, which is the
587
00:32:13.359 --> 00:32:16.119
effect of the drug on the body other than its
588
00:32:16.160 --> 00:32:19.440
effect on the hypothalamus in the pituitary so in the hypothalamus,
589
00:32:19.480 --> 00:32:24.720
and the pituitary. It does what's called negative feedback inhibition,
590
00:32:26.240 --> 00:32:29.720
or it blocks the axgen of estrogen, so it crowds
591
00:32:29.759 --> 00:32:34.400
out estrogen from the estrogen receptor on the hypothalamus and
592
00:32:34.440 --> 00:32:35.240
the pituitary.
593
00:32:35.480 --> 00:32:38.359
Why would I want to take something that would increase
594
00:32:38.480 --> 00:32:42.119
the activity of an estrogen receptor. I just can't find
595
00:32:42.160 --> 00:32:43.160
the rationale for that.
596
00:32:43.559 --> 00:32:47.000
The main rationale behind taking a serm is as a
597
00:32:47.319 --> 00:32:51.720
very temporary measure that is not going to suppress pituitary
598
00:32:51.960 --> 00:32:57.039
or hypothlemic function. If your testosterone is just so drastically
599
00:32:57.079 --> 00:33:01.000
low that it is unlikely to recover anyone anyway. So
600
00:33:01.240 --> 00:33:04.680
most of the time it is not clinically useful and
601
00:33:05.720 --> 00:33:08.759
SERMs should not be prescribed very often, certainly not as
602
00:33:08.880 --> 00:33:14.720
long term testosterone replacement or testosterone optimization in most individuals.
603
00:33:14.759 --> 00:33:20.359
There's always exceptions to everything. But there's five different estrogen
604
00:33:20.519 --> 00:33:26.079
and estrogen related receptors. There's two main estrogen receptors and chlomid,
605
00:33:26.200 --> 00:33:30.119
and every serm has a very unique profile because they
606
00:33:30.240 --> 00:33:34.400
selectively inhibit some receptors in some tissues but not other
607
00:33:34.440 --> 00:33:39.039
receptors and other tissues. For example, chlomid can inhibit receptors
608
00:33:39.039 --> 00:33:42.680
that are in the eye, and it can cause visual
609
00:33:42.759 --> 00:33:48.799
changes blurry vision, especially at higher doses, and it also
610
00:33:49.160 --> 00:33:51.960
acts in every other tissue with the body, so side
611
00:33:51.960 --> 00:33:56.599
effects from chlomid and other selective estrogen receptor modifiers are
612
00:33:56.720 --> 00:33:57.279
very common.
613
00:33:57.640 --> 00:33:59.559
I'd like to take a quick break to acknowledge one
614
00:33:59.599 --> 00:34:03.960
of our sauncers, David. David makes protein bars unlike any other.
615
00:34:04.359 --> 00:34:07.799
Their newest bar, the Bronze Bar, has twenty grams of protein,
616
00:34:07.920 --> 00:34:10.880
only one hundred and fifty calories and zero grams of sugar.
617
00:34:11.280 --> 00:34:13.639
I have to say these are the best tasting protein
618
00:34:13.679 --> 00:34:16.719
bars I've ever had, and I've tried a lot of
619
00:34:16.760 --> 00:34:19.480
protein bars over the years. These new David bars have
620
00:34:19.480 --> 00:34:22.599
a marshmallow base and they're covered in chocolate coating, and
621
00:34:22.679 --> 00:34:26.519
they're absolutely incredible. I of course eat regular whole foods.
622
00:34:26.519 --> 00:34:29.480
I eat meat, chicken, fish, eggs, fruits, vegetables, et cetera.
623
00:34:29.880 --> 00:34:31.480
But I also make it a point to eat one
624
00:34:31.559 --> 00:34:34.039
or two David bars per day as a snack, which
625
00:34:34.119 --> 00:34:36.079
makes it easy to hit my protein goal of one
626
00:34:36.079 --> 00:34:38.440
gram of protein per pound of body weight, and that
627
00:34:38.519 --> 00:34:40.920
allows me to take in the protein I need without
628
00:34:40.920 --> 00:34:44.559
consuming excess calories. I love all the David bronze bar flavors,
629
00:34:44.800 --> 00:34:48.880
including cookie dough, caramel chocolate, double chocolate, peanut butter chocolate.
630
00:34:49.039 --> 00:34:51.960
They all actually taste like candy bars. Again, they're amazing,
631
00:34:52.280 --> 00:34:54.360
but again they have no sugar, and they have twenty
632
00:34:54.400 --> 00:34:57.000
grams of protein with just one hundred and fifty calories.
633
00:34:57.440 --> 00:34:59.320
If you'd like to try David, you can go to
634
00:34:59.440 --> 00:35:02.679
David prote dot com slash huberman. Right now, David is
635
00:35:02.679 --> 00:35:05.079
offering a deal where if you buy four cartons, you
636
00:35:05.119 --> 00:35:07.320
get the fifth carton for free. You can also find
637
00:35:07.400 --> 00:35:10.320
David on Amazon or in stores such as Target, Walmart,
638
00:35:10.360 --> 00:35:12.920
and Kroger. Again, to get the fifth carton for free,
639
00:35:13.039 --> 00:35:17.480
go to David Protein dot com slash huberman. Alcohol. Does
640
00:35:17.519 --> 00:35:21.039
it increase a romantase the enz on the converse distosterone
641
00:35:21.039 --> 00:35:24.960
into estrogen or not? And is there a dose dependence there?
642
00:35:25.559 --> 00:35:29.119
It significantly? Does there is a dose dependence? In general,
643
00:35:29.599 --> 00:35:34.320
I would not recommend more than three to four, you know,
644
00:35:34.400 --> 00:35:38.159
standard drinks. One huge glass of wine is probably five
645
00:35:38.239 --> 00:35:41.400
standard drinks every two weeks. The other thing to keep
646
00:35:41.400 --> 00:35:43.559
in mind with alcohol is as a lot of calories
647
00:35:43.719 --> 00:35:47.000
seven kilo calories program almost as much as fat which
648
00:35:47.039 --> 00:35:50.079
is nine. And then it's also very gaba urgic, so
649
00:35:50.800 --> 00:35:57.280
it can activate inhibitory neurotransmission, and that can also affect
650
00:35:57.320 --> 00:36:01.480
how many how much LH and FSH is released, so
651
00:36:01.519 --> 00:36:06.039
that can also decrease testosterone, almost kind of similar to
652
00:36:06.159 --> 00:36:09.079
how opiates can decrease testosterone.
653
00:36:09.199 --> 00:36:11.760
I want to go back to the prostate and talk
654
00:36:11.760 --> 00:36:14.639
to you about something that's kind of a newer emerging trend.
655
00:36:14.760 --> 00:36:16.800
I know that you've talked to a little bit about
656
00:36:16.800 --> 00:36:20.519
this in previous podcasts that a number of men, I
657
00:36:20.519 --> 00:36:24.519
should say a number of physicians are prescribing low dose
658
00:36:24.599 --> 00:36:28.360
to dalophil also known as cialis, to their male patients,
659
00:36:28.599 --> 00:36:31.199
so in dosage ranges of like two point five milligrams
660
00:36:31.239 --> 00:36:34.079
to five milligrams per day, but not for a rectile dysfunction,
661
00:36:34.159 --> 00:36:37.760
but rather for improving prostate health, and presumably they get
662
00:36:37.800 --> 00:36:40.320
sort of a boost in terms of blood flow to
663
00:36:40.360 --> 00:36:43.880
the genitalia as well, but again not specifically a deal
664
00:36:43.920 --> 00:36:47.679
with a rectile dysfunction, but to deal with prostate health
665
00:36:47.760 --> 00:36:50.400
and blood flow to the prostate. Is that something that
666
00:36:50.440 --> 00:36:54.199
you sometimes often prescribe to your patients, and of what age?
667
00:36:54.559 --> 00:36:58.159
Toad Alifil is a very underrated medication. The age would
668
00:36:58.199 --> 00:37:02.440
kind of depend on the indication, So ted aalaphil is
669
00:37:02.559 --> 00:37:05.719
also a blood pressure medication. It can very slightly decrease
670
00:37:05.719 --> 00:37:09.440
blood pressure, especially at higher doses. At higher doses at
671
00:37:09.519 --> 00:37:12.800
theorem a high dose would be twenty miligrams, not two
672
00:37:12.800 --> 00:37:17.079
point five miligrams, but consistently it can somewhat affect with
673
00:37:17.199 --> 00:37:19.199
the cones in the eye that have to do with
674
00:37:19.280 --> 00:37:21.920
red and green sight, although if you remove it, that
675
00:37:22.000 --> 00:37:25.079
effect is reversed. So basically, if you don't need really
676
00:37:25.079 --> 00:37:27.760
really good red green discrimination, you can take higher doses,
677
00:37:28.159 --> 00:37:31.239
but in general I recommend no higher than ten miligrams
678
00:37:31.239 --> 00:37:37.280
a day, usually just two or five miligrams. One other
679
00:37:37.440 --> 00:37:40.440
benefit or other use of tadalophil is that it increases
680
00:37:40.519 --> 00:37:44.320
the density of the androgen receptor, similarly to L carnotine,
681
00:37:45.599 --> 00:37:48.840
so that's an interesting benefit. Another benefit is that if
682
00:37:48.880 --> 00:37:51.679
you give it to people with nolturia, which is urinating
683
00:37:51.719 --> 00:37:54.480
at night, in general, it will cut the episodes in half,
684
00:37:54.639 --> 00:37:57.199
so it could go from two to one, which can
685
00:37:57.239 --> 00:38:00.000
make a big difference for your sleep, which will secondarily
686
00:38:00.079 --> 00:38:02.760
make a big difference for your growth. Hormone and intostosterone optimization.
687
00:38:03.119 --> 00:38:05.920
Interesting. So you said two point five to five milligrams
688
00:38:05.920 --> 00:38:09.440
per day is kind of typical for these prostate enhancing effects. Yes,
689
00:38:10.000 --> 00:38:13.800
I get a lot of questions about drugs to offset
690
00:38:13.840 --> 00:38:16.320
hair loss. Most of those drugs are going to operate
691
00:38:16.360 --> 00:38:19.000
through the DHD system, the DEHYDRAGSI stosterone system for the
692
00:38:19.039 --> 00:38:21.280
reasons we talked about before, DHG receptors being on the
693
00:38:21.280 --> 00:38:24.199
scalp and causing beard growth on the face. Is it
694
00:38:24.280 --> 00:38:27.440
the case that a number of people taking things like
695
00:38:27.519 --> 00:38:31.519
Propecia and other things to block the DHT or disrupt
696
00:38:31.559 --> 00:38:36.360
the DHT pathway are going to experience diminished sex drive,
697
00:38:36.440 --> 00:38:40.800
diminished you know, kind of motivation and general vigor. And
698
00:38:40.840 --> 00:38:44.320
if so, are there alternatives like topical DHT antagonists that
699
00:38:44.360 --> 00:38:47.440
they might use if they want to keep their hair
700
00:38:47.840 --> 00:38:49.320
but not have those negative effects.
701
00:38:50.000 --> 00:38:53.559
Many people that have just a bit of predisposition, they
702
00:38:53.599 --> 00:38:58.760
can use things that are topical anti androgens. Ketoconazola is
703
00:38:58.760 --> 00:39:00.920
one of them. Caffeine is actually another one.
704
00:39:01.000 --> 00:39:03.480
Wait, you have to explain how this works. How do
705
00:39:03.559 --> 00:39:05.519
people get caffeine into the hair of ollicle?
706
00:39:05.920 --> 00:39:10.280
Topically, the caffeine enters the scalp and crowds out like
707
00:39:10.559 --> 00:39:13.679
somewhat crowds out the androgen. It is a weak effect.
708
00:39:14.280 --> 00:39:18.239
It's likely just strong enough to be clinically significant. Usually
709
00:39:18.280 --> 00:39:22.119
caffeine is put into formulations with other things like ketoconazol
710
00:39:22.320 --> 00:39:26.960
that are also weak anti androgens. Of notes, spronlactone can
711
00:39:27.039 --> 00:39:30.599
be prescribed topically, but it is absorbed systemically because the
712
00:39:30.639 --> 00:39:34.519
size of the molecule, So unless your doctor specifically prescribes
713
00:39:34.559 --> 00:39:36.840
that for you, especially as a male, do not use
714
00:39:36.880 --> 00:39:42.800
topical spronalactone. Topical finasteride is also a smaller molecule, so
715
00:39:42.880 --> 00:39:47.000
it is also systemically absorbed, but it is not extremely
716
00:39:47.039 --> 00:39:51.000
well systemically absorbed. If you take topical phinasteride, then usually
717
00:39:51.039 --> 00:39:55.519
your systemic DHT will decrease by about thirty percent. Topical
718
00:39:55.559 --> 00:39:59.639
detastoride is likely a tiny bit systemically absorbed, but it's
719
00:39:59.719 --> 00:40:02.360
unique because it's half life is much faster at a
720
00:40:02.400 --> 00:40:06.440
lower dose, So topical do testeride will not affect your
721
00:40:06.480 --> 00:40:09.360
systemic DHD at all, And I've seen this anecdotally on
722
00:40:09.480 --> 00:40:11.960
many people on topical do testeride therapy.
723
00:40:12.360 --> 00:40:14.960
On behalf of the audience, and just for myself, thank
724
00:40:15.039 --> 00:40:17.320
you so much. You have an immense amount of knowledge
725
00:40:17.320 --> 00:40:20.239
and you're exquisitely good at sharing it with people in
726
00:40:20.280 --> 00:40:22.679
an actual way, So thank you, my pleasure,
