In this episode, I’m joined by Dr. Scott Sherr, a board-certified internal medicine doctor and expert in integrative and hyperbaric medicine. He’s shining a light on a little-known brain chemical called GABA — often described as your brain’s “off switch.”

Dr. Sherr believes GABA deficiency is one of the most overlooked drivers of mental fatigue, stress, and sleep issues today. And more importantly, he shares powerful, practical ways to support GABA naturally — beyond just popping supplements. We’re talking cutting-edge tools like medicinal mushrooms (a.k.a. fungiceuticals), targeted lifestyle shifts, and more.
