Imagine accurately determining the status of your skin’s age to tell whether it is younger or older than your chronological age, and then use this technology to determine whether expensive anti-aging serums and creams are effective, or actually causing more harm than good. Amazing, right? This is precisely the technology Dr. Carolina Reis Oliveira and her fellow stem cell biologists at OneSkin cre...

This fundamental piece of our functional medicine toolkit continues to progress, and today we’re zooming way out from just patching up the gut. Dr. Fabian and I dive into the dynamic nature of the barrier, incl...

How much do we really know about the microbiome? What does it take to identify new probiotic strains and their associated health benefits? When should we leverage precise single strains and when is it more effective to use synergistic blends? I am grateful to talk again with the brilliant scientist and incredibly courageous entrepreneur, Dr. Colleen Cutcliffe. Colleen has over 20 years experience...

Dr. Michael Roizen is an extraordinarily well-read, well-researched, and experienced physician in the field of longevity medicine. He dates his first interest in the field back to 1979 as head of an intensive care unit, when he recognized that patients who were biologically younger dramatically reduced their risk for post-operative disease and death. Since then, he has worked tirelessly in many wa...

Why are we often resistant to tackling stress and preprogrammed thought patterns? It’s a curious phenomenon that occurs even in those of us who really know the central role these psychological factors play in health, disease, and even aging. That’s why I'm thrilled to interview resilience expert Dr. Stephen Sideroff. After all, a full 25% of the bio-age clock we used in our clinical study is drive...

In this New Frontiers in Functional Medicine® podcast, Dr. Tom Fabian delivers a well-justified challenge to our current thinking and a chance to build a more nuanced approach that will improve patient results around the topic of hydrogen sulfide, a compound that we have typically thought of as the “problem child” behind certain difficult SIBO cases. However, there is a LOT more to know about it,...

Functional medicine providers are well versed in addressing the myriad manifestations of autoimmune disease, but while our success rates are remarkably high, we still aren’t always able to help everyone using current toolsets (labs, sophisticated elimination diets, gut protocols, and so on). Enter Mymee, a digital app and coaching platform that helps plug that gap – this sophisticated tool helps i...

It’s always a pleasure to tap into Dr. Raffaele’s brain, and in this podcast he doesn’t disappoint.
