Dr. Phil Strandwitz, Founder of Holobiome, discusses the gut-brain connection and pioneering microbial therapies. Trillions of gut bacteria influence neurotransmitter activity, mood, and cognition. Imbalances in the microbiome may underlie mental health issues. Startups like Holobiome aim to develop microbiome-based treatments including fecal transplants. Lifestyle changes like diet, prebiotics, and probiotics can support gut health. This conversation will change how you think about the gut-brain connection.
