NAD+ in the Spotlight: New Insights on Boosting Cellular Resilience

I’m really excited about this one—Dr. Greg Kelly is back with us, and we’re diving deep into NAD, a molecule that’s finally getting the attention it deserves. If you’ve heard me talk about NAD before, you know how foundational it is for energy, longevity, and cellular health, but I’ve got to say—after today’s conversation, I’m looking at it in a whole new way. Dr. Kelly brings a fresh perspective on how NAD influences mitochondrial function, DNA repair, and even the aging process. He’s challenging the way we think about aging, and I’m here for it. For me, NAD is no longer just a side player—it’s going front and center in my supplement stack. If you’re wondering how it might show up clinically, whether it’s in fatigue or other signs of cellular stress, you’ll want to listen in. And if you’re like me, you’ll be adding this one to your regular routine. Have a listen and get ready to rethink how you approach aging and energy. ~DrKF

The Podcast After the Podcast: Revisiting Age Reversal with Dr. Greg Fahy

The Podcast After the Podcast: More on Age Reversal with Dr. Greg Fahy

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

Innovative Approaches to Restoring Brain Function After Concussion and TBI

Innovative Approaches to Restoring Brain Function After Concussion and TBI

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

An HRT Revolution is Underway. Are You Ready to Individualize Recommendations for Hormone Health?

“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.

AI-Driven Brain Imaging: A Game Changer in Preventing Cognitive Decline with Owen Phillips, PhD

AI-Driven Brain Imaging: A Game Changer in Preventing Cognitive Decline with Owen Phillips, PhD

How do we prevent cognitive decline before it even begins? The answer might not be what you think. I’m thrilled to share my conversation with Dr. Owen Phillips, a Stanford-trained neuroscientist and founder of BrainKey, who is helping to revolutionize brain care. His team is using AI technology to uncover subtle brain changes long before they result in disease—transforming the way we approach brain health. And here’s the kicker—Dr. Phillips reveals why protecting your brain actually starts with protecting your vasculature—No surprise when you consider it’s essential for feeding this power-hungry organ. This shift in thinking could change how we all approach cognitive health moving forward. We touch on heavy metal toxicity, long Covid, sports injuries and more, so if you’re ready to rethink brain health and prevention, this conversation will leave you with a fresh perspective.

Beyond Retinol: The Role of Urolithin A in Aging and Skin Health

Beyond Retinol: The Role of Urolithin A in Aging and Skin Health

Talking with Dr. Julie Faitg was a powerful reminder of just how much we’re discovering about mitochondria and aging. When you pair an elite mitochondrial scientist with a breakthrough nutrient like Urolithin A, the insights go beyond what you’d expect. Julie gives us this incredible look into how we can actually change the course of aging at the cellular level. This conversation made me rethink what we know about supporting long-term health and resilience, and I think it will do the same for you. It’s one of those big-picture, eye-opening conversations that I can’t wait for you to hear.
