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.

In this special preview of the Functional Medicine is Longevity Medicine™ Masterclass happening on September 17- September 19, 2025, Dr. Kara Fitzgerald sits down with three leading voices in medicine and research: <p> - Dr. Bob Rountree: functional medicine pioneer in integrative approaches to health <p> - Dr. Dale Bredesen: internationally recognized expert on Alzheimer’s prevention and reversal <p> - Dr. Charles Serhan: Harvard researcher on inflammation resolution and aging biology <p> Together, they explore how functional medicine reframes longevity by addressing root causes, supporting cognitive health, and resolving chronic inflammation. <p> Whether you’re a clinician, health professional, or simply passionate about living longer and healthier, this conversation offers a glimpse into the science and practical applications that are transforming longevity medicine. <p> WATCH NOW TO LEARN: <p> - Why functional medicine is central to extending healthspan - The latest insights on Alzheimer’s prevention and brain health - How inflammation resolution impacts aging and chronic disease - What to expect in the full Functional Medicine is Longevity Medicine™ Masterclass <p> Learn more & register for the Masterclass here: www.functionalmedicineislongevitymedicine.com <p> THANKS TO OUR SPONSORS <p> DIAMOND <p> DUTCH: https://dutchtest.com/for-providers </p> Biotics Research: https://www.bioticsresearch.com/ </p> GOLD </p> TimeLine Nutrition: https://tinyurl.com/bdzx2xms </p> Vibrant Wellness: https://www.vibrant-wellness.com/ <p> EXCLUSIVE OFFERS FROM OUR SPONSORS <p> OneSkin: Get 15% off OneSkin with the code DRKARA at http://oneskin.co/DRKARA <p> Discover why MitoQ’s mitochondria-targeting is a critical step for your healthspan and longevity strategy. http://mitoq.com/drkara

It was a pleasure to sit down with Dr. Nir Barzilai for a conversation that turned out to be both lively and thought-provoking. His decades of research on centenarians, biological age, and the hallmarks of aging have shaped how we think about longevity—and what’s possible when we start targeting aging itself, not just individual diseases. <p> We get into the science behind why some people live 20–30 years longer and healthier, and what it means to measure the biological age of individual organs. But we also hit a few sparks—especially when it comes to nutraceuticals and the role of metformin in prevention. I don’t agree with everything you’ll hear, and I followed up with Dr. Barzilai afterward to unpack some of the more provocative claims. We may just need a second round for this one... stay tuned. <p> Check out the show notes at www.drkarafitzgerald.com/fxmed-podcast/ for all the relevant links and resources. ~DrKF </p> Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources. <p> GUEST DETAILS Nir Barzilai M.D. Director of the Einstein Institute for Aging Research Professor of Medicine and Genetics President of the Academy for Health & Lifespan Research <p> Website: https://einsteinmed.edu/faculty/484/nir-barzilai <p> Email: [email protected] <p> Dr. Nir Barzilai is a pioneer in aging science, known for his work on centenarians, the biology of aging, and the TAME trial.

I’ve been watching the science behind Calocurb evolve over the last year, and I have to say—this is one of the most exciting clinical tools I’ve seen emerge in the metabolic space in quite some time. A hops-derived compound that stimulates endogenous GLP-1, CCK, and PYY—without a prescription or injection? That’s a big deal, especially for patients struggling with appetite regulation, weight plateaus, or the aftermath of GLP-1 discontinuation. </p> In this episode, I sit down with Sarah Kennedy, founder of New Zealand-based Calocurb, to talk about the years of government-funded research that led to this discovery, the remarkable clinical outcomes they’ve seen so far, and how I’ve personally used it in my practice with excellent results. If you’re looking for science-backed, natural strategies to support appetite control, fasting, or GLP-1 transitions—this one’s worth a listen. ~DrKF </p> Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources. <p> GUEST DETAILS Sarah Kennedy, Founder and CEO of Calocurb Ltd. <p> Email: [email protected] LinkedIn: https://www.linkedin.com/in/sarah-kennedy-0a840b13/ <p> Sarah Kennedy, BVSc, is a veterinarian and health industry leader with 20+ years in nutrition science and innovation. Now CEO of Calocurb, she brings a unique perspective on natural GLP-1 activation—bridging plant-based research, gut physiology, and clinical application. </p> THANKS TO OUR SPONSOR: Calocurb <p> EXCLUSIVE OFFER FOR NEW FRONTIERS LISTENERS <p> Manage cravings and feel full faster with Calocurb, a 100% natural capsule that supports healthy weight management.
