WHO'S BEHIND THIS

Hi, I'm Kayla Barnes-Lentz.

I'm a women's health and longevity researcher building the protocol I wished existed. For a decade I've been tracking thousands of my own biomarkers, working alongside female MDs and PhDs, and translating the science of female physiology into something anyone can actually follow. Previously, I was CEO and co-owner of one of the most innovative longevity clinics in the world. This library is the result, open, free, and updated as the evidence evolves.
