  The Estrogen Effect Nobody Talks About | Kiran Krishnan 05.05.2026 1u 1min

  Cardiovascular health and longevity are deeply influenced by aging, perimenopause, and systemic changes that extend far beyond cholesterol markers alone. In this episode of New Frontiers in Functional Medicine, Dr. Kara Fitzgerald sits down with Kiran Krishnan to explore the biology of vascular aging, endothelial dysfunction, and metabolic changes that emerge in midlife and beyond. As estrogen declines during perimenopause, patients often experience shifts in lipid metabolism, weight regulation, and overall metabolic resilience—driving increased cardiovascular risk. This conversation dives into the critical role of the endothelial glycocalyx, nitric oxide signaling, and the gut microbiome in maintaining vascular integrity and systemic health. Dr. Fitzgerald and Kiran connect the dots between gut health, cardiovascular disease, joint degeneration, and systemic inflammation, offering a systems biology approach that is highly relevant for functional medicine practitioners. You’ll also hear how targeted interventions—specifically Arterosil, Vascanox, and Cartigenix—can be used synergistically to support endothelial health, nitric oxide production, microbial balance, and joint integrity. Topics covered include: - Endothelial glycocalyx dysfunction and cardiovascular risk - Nitric oxide signaling and vascular health - Perimenopause, estrogen decline, and metabolic changes - Gut microbiome influence on cardiovascular and joint health - Anabolic vs catabolic balance in aging - Clinical applications for Arterosil, Vascanox, and Cartigenix - Moving beyond LDL: a systems-based approach to heart health This episode provides a clinically grounded, functional medicine perspective on aging, cardiovascular disease prevention, and whole-body resilience.

  Platelet-Derived Exosomes in Aesthetics: Data, Safety, and Real-World Use Cases 06.01.2026 46min

  Exosomes are becoming one of the most talked-about tools in regenerative medicine, but not all exosomes are created equal. In this episode of New Frontiers, Dr. Kara Fitzgerald talks with Alisa Lask, CEO of Plated Skin, about the science behind platelet-derived exosomes and why their signaling pathways matter for repair, renewal, and changes in skin appearance. We explore how discoveries in cardiology led to this technology, what early clinical studies are showing, and why source and preparation are critical when evaluating any exosome-based approach. A clear, grounded look at a fast-moving field for clinicians who want to understand what’s real, what’s emerging, and what deserves attention next. Full show notes + references: https://www.drkarafitzgerald.com/fxmed-podcast/ GUEST DETAILS Alisa Lask is the CEO of Rion Aesthetics, where she is driving innovation in regenerative aesthetics with platelet-derived exosomes and leading research in areas like hair restoration and skin appearance.

  The Hidden Immune Signal Accelerating Aging & the Beta-Glucan That Fixes It 02.12.2025 1u 5min

  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.
