In this episode of the Innovations and Clinical Implementation podcast recorded at LongevityFest 2025, hosts Jessica Carter and Dr. Lexi Gonzales explore advanced cellular rejuvenation strategies with Dr. Greg Kelly—a naturopathic physician, author of Shape Shift, and Chief Product Officer at Qualia who is a leading expert in nootropics and longevity science. Dr. Kelly outlines a "gardening" approach to cellular health, advocating for an intermittent "hit-and-run" dosing protocol where senolytics are used to "prune" inflammatory senescent cells (the "yellow leaves") before introducing stem cell support, rather than using daily dosing which can lead to adaptation or exhaustion. He utilizes the analogy of the "four doors" of cellular stress to explain why clearing the biological terrain of "zombie cells" is a necessary prerequisite for effective stem cell therapy, ultimately recommending a practical monthly cycle—such as two days of senolytics followed by four days of stem cell support—to reduce systemic inflammation and improve cognitive function.

On the next episode of Redefining Health, we'll be joined by Christopher Davis to dive into the fascinating topic of metabolic health—what it truly means and how practitioners can effectively discuss it with their patients. Metabolic health is deeply tied to mitochondrial function, the "powerhouses" of our cells that drive energy production. When mitochondrial health is compromised, it can lead to a range of issues, from poor energy levels to chronic diseases. Factors such as oxidative stress, poor diet, lack of exercise, and environmental toxins all play a role in mitochondrial dysfunction. In this episode, we'll explore: What metabolic health really means and why it's essential for overall well-being. How practitioners can simplify the concept for patients and emphasize the importance of lifestyle factors like diet, exercise, and stress management. The role of VO2 Max as a powerful yet underutilized tool for assessing cardiovascular and metabolic health. VO2 Max, which measures the body's ability to utilize oxygen during exercise, is one of the best indicators of mitochondrial and cardiovascular health. Despite its value, it's not used enough in clinical practice. We'll discuss why this metric matters and how it can be integrated into patient care to provide a more comprehensive picture of health.   Join us for this insightful conversation as we redefine what it means to achieve and maintain metabolic health.

In this episode of the Innovations and Clinical Implementation podcast recorded at LongevityFest, host Tom Blue interviews Harry Bane, CEO of Lifespan.MD, about a novel investment model for concierge medicine dubbed "Entrepreneurial Equity".
