17. Rebirth of the Gut with Thaena
32m | May 13, 2026In this episode, I sit down with Dr. Andrea McBeth, Co-Founder and CEO of Thaena®, to explore one of the most fascinating frontiers in gut health: postbiotics derived from healthy microbiomes.
We break down the science behind fecal transplants and how Thaena has transformed that concept into a sterilized, accessible postbiotic—capturing the powerful communication molecules our gut bacteria produce without the risks of live bacteria. From short-chain fatty acids like butyrate to neurotransmitter precursors and immune-modulating compounds, we dive into how these molecules influence everything from digestion and inflammation to brain health and metabolism.
We also talk about real-world applications—why traditional gut protocols sometimes fail, how postbiotics can help “jumpstart” the microbiome, and their potential role in conditions like IBS, SIBO, constipation, and even neuroinflammatory disorders.
This conversation challenges the way we think about probiotics, nutrition, and the future of medicine—highlighting just how much we still have to learn about the ecosystem inside us.
