Dr. Kara Fitzgerald FxMed, Longevity & Epigenetics
A clinical podcast for practitioners where a functional medicine doctor interviews leading researchers on the science behind longevity and chronic illness.
This is a dense, science-heavy interview show for functional medicine practitioners. Host Dr. Kara Fitzgerald interviews top-tier researchers and clinicians (PhDs, MDs) to break down the latest studies and clinical protocols on topics like epigenetics, mitochondrial health, and chronic illness. The conversations are framed for a clinical audience, focusing on diagnostics, treatment strategies, and the mechanisms behind them.
“Unlike broader wellness podcasts, New Frontiers is explicitly for practitioners. Dr. Fitzgerald's own clinical and research background allows her to go deep on mechanisms and protocols, asking the specific questions a fellow clinician would have about diagnostics, side effects, and treatment application.”
Who hosts this show
Dr. Kara Fitzgerald, ND, IFMCP, is a functional medicine clinician, researcher, and author based in Sandy Hook, Connecticut. She is the medical director of the Sandy Hook Clinic, lectures globally on longevity and epigenetics, and is on the faculty at the Institute for Functional Medicine (IFM).
