Why Gut Health Might Be the Key to Aging, Alzheimer’s & Obesity, with Daniel Winer (Co-Founder of Propion) - Nicholas Tubach (Co-Founder & CEO of Propion)
Can your gut control your lifespan? What if molecules produced by your microbiome could prevent obesity, Alzheimer’s, and inflammation, just by supporting the right immune response?
In this episode of The Augmented Life, Michael Tiffany sits down with Dr. Dan Winer and Nicholas Tubach, the team behind Propion, a new science-backed startup exploring the frontier of postbiotics, specifically indole metabolites like indole-3-propionic acid (IPA). Dr. Winer unpacks how decades of immunometabolism research led him to the gut-liver-brain axis, and how he and Nicholas translated that science into a product aimed at improving healthspan, not just lifespan.
We cover:• The role of adaptive immune cells in obesity• How the gut barrier protects (or harms) other organs• What postbiotics like IPA actually do• How Propion went from gaming chat to startup launchWhy your microbiome might be aging you faster than you think—
