FxMed PodcastLeave a comment

I was thrilled to finally sit down with Dr. Greg Fahy, whose groundbreaking work in aging has truly reshaped our understanding of what’s possible. His 2019 TRIIM study, showing clear biological age reversal through thymus regeneration, was a game-changer. The scientific community was stunned, and rightly so—this was the first real evidence that we can turn back the clock on aging. But Dr. Fahy isn’t stopping there. His ongoing studies hold incredible implications for the future, from potentially reversing autoimmunity to avoiding transplant rejection. Even more exciting is the possibility of creating a standardized protocol that could help other clinicians use these principles in practice. We’re on the brink of something truly revolutionary, and I’m already looking forward to having him back to hear what’s next. This conversation is a must-listen for anyone passionate about the future of longevity. ~DrKF

The brain’s ability to recover after trauma is astonishing—and often overlooked in conventional care. In this episode of New Frontiers in Functional Medicine, I sit down with Dr. David Musnick, a long-time friend and brilliant clinician, to explore how we can unlock the brain’s full potential for healing. Dr. Musnick challenges the standard of care for traumatic brain injuries and post-concussion syndrome, introducing a functional medicine approach that integrates advanced tools like Frequency-Specific Microcurrent, targeted nutritional strategies, and personalized interventions. His insights into the stages of recovery, the importance of addressing neuroinflammation, and the role of the gut-brain connection were a true “aha” for me. We also dive into groundbreaking methods for reversing secondary brain damage, a concept that could change everything for patients and practitioners alike. This conversation is packed with actionable takeaways and hope for those navigating brain injuries, cognitive impairment, or persistent post-concussion symptoms. You don’t want to miss it.~DrKF

“What if the key to optimizing hormone therapy isn’t just in the hormones themselves, but in understanding the way they break down in the body?” In today’s episode, I’m thrilled to share my conversation with Dr. Allison Smith, a leader in hormone testing and a trusted expert at Precision Analytical, home of the DUTCH test. Dr. Smith’s work has helped revolutionize how we understand hormones, moving beyond simple serum testing to more comprehensive methods that examine how hormones are metabolized and how their breakdown products affect patient health.

There’s so much to unpack in this episode—I’m excited to dive into it with you. We cover cutting-edge tools like MALDI-TOF technology, which gives us a whole new level of precision in identifying microbial species. We also explore the bi-directional relationship between GLP-1 production and gut dysbiosis—something you might not be considering enough in your metabolic patients. Chronic stress and its deep impact on gut health and secretory IgA also come into focus, offering key insights into gut permeability, inflammation, and immune health. And we tackle the challenging questions around Akkermansia—whether it’s high, low, and what those levels really mean clinically. There’s so much to gain for your practice, so download your GI360 Sample Report and let’s dive in! ~DrKF

If you prioritize your health, you’re likely familiar with the foods and supplements that support muscle growth, heart health, and a robust immune system. But have you considered your brain health? Our cognitive well-being underpins our aspirations, achievements, and life experiences. We all aspire to be among the remarkable few whose minds seem as sharp and vital at age 80 or 90 as they did at 30 or 40. So, how can we start nurturing our brain health today, to maximize supporting for a healthy mind for decades to come?

In this episode, I had the pleasure of speaking with Dr. Valerie Gershenhorn, who offers a truly unique perspective on tackling some of the most stubborn skin conditions we encounter in our practices. Her approach is both refreshing and deeply rooted in functional medicine principles. As someone who has navigated the complexities of dermatological health, I found our conversation rich with clinical pearls that I believe will resonate with many of you. From her insights into the gut-skin axis to the practical steps she takes with both adults and children, there’s a wealth of information here that can be directly applied to your practice. I’m confident you’ll find her strategies as valuable as I did.

Age Reversal, Thymus Renewal & The Future of Longevity with Dr. Greg Fahy

You Are Only As Young As Your Immune System with Dr. Greg Fahy

Dr. Fahy’s research was the first to demonstrate the potential of biological age reversal as measured by all epigenetic clocks available in 2019. This was an extraordinarily exciting moment in science.Hear all about that journey and what he and his team are working on now. Still underappreciated (in my opinion) is the fact that his protocol regenerates the thymus gland in older individuals. The implications of this are massive.

Valuable Insight into Gut Health from DUTCH Hormone Testing

Functional Medicine for Consumers, Functional Medicine for ProfessionalsLeave a comment

When seeking health advice, we’ve all heard the recommendation, “start with the gut.” Whether we have high cholesterol or heavy periods, it always somehow comes back to the gut, right? Why is that? Well, it’s probably because the state of our gut affects the health of every organ system in our body, and because of this, a healthier gut tends to improve how we feel and function on a day-to-day basis. Many people only think to use a stool test to evaluate gut health, but the DUTCH Test may also yield valuable insights through its measurement of cortisol, hormone metabolites, and organic acids.
