ABOUT THIS EPISODE
What if Parkinson's disease doesn't start in the brain at all, but in the gut? In this episode of The Dr. K Show, Dr. Michael Karlfeldt sits down with Martha Carlin, citizen scientist, founder of BiotiQuest and The Bio Collective, and author of Connected, to unpack the 22-year journey she and her husband John lived after his Parkinson's diagnosis at age 44. Martha explains how removing processed food and GMO soy changed John's visible tremors within months, and how that discovery pulled her out of a corporate career and into two decades of independent microbiome research.
The conversation moves through the science she uncovered along the way: the glycocalyx, the gel-like layer coating every cell in the body; how endotoxin from gut bacteria drives chronic inflammation across dozens of diseases; why H. pylori can quietly eat the dopamine that Parkinson's medication is supposed to deliver; and a striking account of fecal transplants shrinking tumors in cancer patients within two weeks. Martha also breaks down why endurance athletes face a hidden Parkinson's risk tied to the very same gut mechanisms. If you or someone you love is navigating a Parkinson's diagnosis, or you simply want a clearer picture of how the gut shapes chronic disease, this episode reframes the conversation.
