The Hidden Immune Signal Accelerating Aging & the Beta-Glucan That Fixes It

Beta-glucans might be one of the most overlooked levers in immune resilience, and that has major implications for longevity. Talking with my long-time friends and colleagues Drs. Bob Rountree and Chris D’Adamo reminded me just how powerful this molecule truly is. The clinical reach here is stunning, from immune aging and cancer support to vaccine response, gut–brain effects, and overall resilience. What struck me most is how beta-glucans help the innate immune system respond more effectively over time, from overtraining and chronic infections to vaccine responsiveness. Clinicians really need this on their radar. I think you’re going to find this conversation eye-opening. ~DrKF Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources.
