Dr. Kara Fitzgerald | New Frontiers in Functional Medicine, Longevity, Epigenetics

Dr. Tom Fabian, a translational scientist and microbiome research expert, sheds light on bile acid imbalances and their role in gut health. He discusses how specific types of inflammation and microbial patterns can guide interventions to improve patient outcomes. Notably, Tom connects low butyrate levels to inflammatory bowel disease and reveals the surprising ways some fibers might exacerbate gut irritation. He emphasizes using StoolOMX and GI-MAP tests for precision medicine in complex cases, making science practical for clinicians.

Can functional medicine unlock the secrets to healthy aging? 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: - Dr. Bob Rountree: functional medicine pioneer in integrative approaches to health - Dr. Dale Bredesen: internationally recognized expert on Alzheimer’s prevention and reversal - Dr. Charles Serhan: Harvard researcher on inflammation resolution and aging biology Together, they explore how functional medicine reframes longevity by addressing root causes, supporting cognitive health, and resolving chronic inflammation. 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.

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. 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.

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. 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 Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources.

In this very special episode, I have the privilege of turning the tables on Dr. Kara Fitzgerald as we celebrate 10 years of the New Frontiers podcast. I’ve been honored to walk alongside Kara on much of this journey—as a colleague, a collaborator, a mentee, and a friend—and it’s been incredible to witness the evolution of both her work and the field itself. Together, we reflect on the stories, science, and people who have shaped this podcast—and the remarkable growth of epigenetics, personalized medicine, and functional medicine along the way. From early conversations around methylation and aging to hosting pioneers like Dr. Jeff Bland, Dr. Sidney Baker, and Dr. Charles Serhan, New Frontiers has become a living archive of how this field has moved forward. As we talked about during the conversation: “Everybody is a piece of this ecosystem, and everybody has their role... It’s really cool to be part of that community.” This episode is a celebration of that collective journey—and a look at where we’re headed next. ~Romilly Hodges MS CNS Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources.

This is a really exciting conversation with Dr. Davide D’Amico from Timeline, where we’re taking a closer look at Urolithin A and heart health. It should come as no surprise that this mitochondrial wonderkin of a nutrient is showing promise here—especially when you consider that 40% of the heart’s weight is mitochondria. That’s an extraordinary factoid, and one that really shifts how we think about aging in the cardiovascular system. What’s particularly compelling in this new preclinical research is that restoring mitochondrial function may do more than just improve ejection fraction. It may also have ripple effects on other hallmarks of aging—like chronic inflammation, cellular stress signaling, and impaired autophagy. I’m thrilled Timeline is continuing to invest in both preclinical and clinical research on this front—and yes, I’m totally nerding out over what they’re up to. ~DrK Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources.

In this conversation, Rana el Kaliouby, an Egyptian-American AI scientist and co-founder of Blue Tulip Ventures, explores the intersection of artificial intelligence and human emotions. She discusses how AI can enhance empathy in healthcare and family therapy through innovative technologies like Happy Pillar. The talk delves into ethical considerations of AI, emphasizing privacy and consent. Rana also underscores the importance of integrating AI in education, fostering understanding among young and old, to create a future where technology promotes genuine human connection.

In many ways, the legal side of functional medicine can feel like the Wild West—uncertain, unregulated, and full of risks. The reality is, we all want to have our practices legally buttoned up, but navigating the legal landscape can feel overwhelming—and expensive. What Scott Rattigan, creator of Functional Lawyer, shares in this episode is a real game-changer. He not only breaks down the complexities of the legal side of things but also offers real solutions for us—solutions that can make sure we're covered without the stress and uncertainty that often comes with it. Whether you're just starting out or growing your established practice, you're going to get actionable insights on how to avoid common legal pitfalls, protect your practice, and actually move forward with confidence. It’s a topic that’s been an unmet need for so long, and I'm so excited to bring this to you. ~DrKF Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources.

I’ve been looking forward to sharing this conversation with you because it’s one I’m truly passionate about. Today, we’re diving into the DunedinPACE epigenetic clock with one of its creators, the brilliant Dan Belsky. It’s a tool I use regularly with my patients, and one that’s transforming how we approach aging and interventions. While this show is a bit more technical than usual, the science is fascinating, and the real-world applications are incredibly valuable. This isn’t just about theory—it’s about practical insights that can change how we measure aging and track the effectiveness of the treatments we offer. Stick with us, and you’ll walk away with actionable knowledge that can make a difference in your practice. ~DrKF Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources.
