What does it take to show up as a strong, present, and resilient father in a world that gives most men no clear blueprint?

In this episode with John Schott, you’ll explore why so many dads feel depleted, distracted, and unsupported, and how that ties directly to poor recovery, low energy, and lack of structure. You’ll also discover how simple systems built around circadian rhythms, movement, hydration, and family routines can restore your physical edge while improving patience, focus, and leadership at home. This conversation goes beyond surface-level advice, exploring what truly shapes a man's identity and why the way he shows up as a father and leader ripples into his family and our broader culture.

John Schott is a bodyworker, wellness practitioner, and founder of the Conscious Dad Protocol, a system designed to help men optimize their physical health, emotional resilience, and leadership within the family unit. With years of experience in fascia work, recovery techniques, and holistic living, John combines ancestral principles with modern strategies to create practical systems that support both performance and presence.

Through his work, he focuses on helping fathers build stronger bodies, clearer minds, and deeper connections with their families while navigating the demands of modern life.

How To Be A Better, More Present Father (& Not Get DAD-BOD!) with John Schott

Full Show Notes:https://bengreenfieldlife.com/nadplus 

In this fascinating episode, Dr. Nichola Conlon, molecular biologist and founder of Nuchido, breaks down what NAD actually is, what it does inside your cells, and why most popular strategies for boosting it, including NAD IVs, patches, and high-dose NR or NMN, may be fundamentally flawed based on molecular biology. 

You’ll discover why NAD declines by half every 20 years, why the NAMPT enzyme and not a shortage of raw material is the real bottleneck, and why flooding the body with precursors without fixing the salvage pathway can actually strain your methylation pathways rather than raise NAD. 

You’ll also explore how inflammation through the cluster of differentiation 38 (CD38) enzyme silently drains NAD faster than almost anything else, what a gold standard double-blind placebo-controlled crossover clinical trial on Nuchido TIME+ actually showed, and why NAD sits at the intersection of energy production, cellular repair, sleep, skin health, and biological aging. 

Dr. Nichola Conlon (BSc, MRes, PhD) specializes in cellular aging. After a career in drug development, Dr. Nichola founded Nuchido, driven by her belief that cutting-edge science should not lie hidden. At Nuchido, Dr. Nichola’s work focuses on delivering disruptive innovation in the field of anti-aging, rejuvenation, and healthspan. It has led to the development of Nuchido TIME+, a dietary supplement clinically proven to boost NAD+ and reverse biological age. Unlike standard precursors such as NMN or NR, Nuchido TIME+ uses a systems-based approach to target the root causes of NAD+ decline.

Could NAD IVs Be Bad For You (& How To Boost NAD Naturally), With Dr. Nichola Conlon

Full Show Notes: https://bengreenfieldlife.com/trupodcast

In this episode with repeat guest Dr. Matt Dawson, you’ll discover how epigenetic testing analyzes DNA methylation to reveal how fast you’re biologically aging, what’s driving your health, and your risk for disease. You’ll explore how these signals can detect chronic disease risk earlier than traditional labs, and how TruDiagnostic built the TruHealth Test by analyzing ~1,000 biomarkers to pinpoint the most meaningful health indicators. We also break down the TruAge Test, covering biological age, pace of aging, and organ-specific aging, plus insights from my own results. We discuss how AI and large language models (LLMs) identify which interventions actually improve specific biomarkers, and what truly moves the needle for longevity, from caloric restriction and GLP-1 drugs to the often-overlooked impact of relationships, stress, and recovery.

👉Receive 20% off your TruAge + TruHealth kit with code BEN20 here.

Dr. Matt Dawson is a physician-entrepreneur focused on genomics and epigenetics. He has founded six companies, authored two medical textbooks, contributed to over two dozen scientific publications, and lectured in more than 20 countries. As founder of Wild Health, he built a nationwide genomics-based precision medicine practice later acquired by a publicly traded tech company. He now serves as CEO of TruDiagnostic, an epigenetic longevity laboratory leveraging AI and biomarkers to transform chronic disease diagnosis.
