In this Huberman Lab Essentials [/essentials] episode, my guest is Kyle Gillett, MD, a dual board-certified physician in family medicine and obesity medicine, and an expert in hormone optimization. We discuss science-based tools for optimizing male hormones across the lifespan, including the role of bloodwork, nutrition, and exercise in supporting healthy hormone levels. We also discuss testosterone therapy, hair loss, prostate health, and supplements such as creatine, L-carnitine, Tongkat Ali, and Fadogia agrestis.
