What if I told you there's an organ in your body with more cells than the Milky Way has stars—and most doctors barely think about it? In this episode of Extend, I sit down with Dr. Zain Kassam, a gastroenterologist turned microbiome researcher who's pioneering how we understand the trillions of organisms living in and on us.
We dive into why your gut bacteria aren't just bystanders—they're actively producing molecules that affect your mood, metabolism, immune system, and even longevity. We also explore the gut-brain connection, why not all probiotics are created equal, and how the microbiome influences everything from depression to skin health.
Dr. Zain Kassam is a gastroenterologist, microbiome researcher, and Chief Medical Officer at Seed Health. He trained at McMaster University, Harvard, and MIT, where he pioneered clinical applications of microbiome science. He's led groundbreaking research on fecal transplants and develops evidence-based probiotic therapies.
