Embodied With Kathy Covington

Alexander Audit | Chief Scientific Officer | NAD ClinicAlexander Audit is a former chemical engineer turned integrative clinician, trained in traditional Chinese medicine and nutritional medicine. As Chief Scientific Officer of NAD Clinic — a global leader in cellular health and performance medicine operating in more than 40 countries — he bridges hard science with real-world application. His work centers on NAD, the molecule at the heart of cellular energy, brain health, and longevity.Last week, Alexander Audit joined Kathy at the Global Wellness Summit in Dubai to break down the science of NAD — what it is, why levels begin declining as early as our 30s, and how that shows up as fatigue, brain fog, and accelerated aging. He walked us through the history of NAD therapy, its powerful applications in mental health and addiction recovery, and how methylene blue works alongside it to boost mitochondrial energy. If you haven't listened to Part 1 yet, it's a great place to start.This week, the conversation goes deeper into the practical side of longevity. Alexander shares the lifestyle habits that can naturally raise your NAD levels — and the everyday choices quietly draining them. From the surprising cellular cost of a single drink of alcohol to the science behind intermittent fasting and why muscle mass is one of your greatest longevity assets, this episode is packed with actionable insight.We also explore how NAD Clinic approaches performance optimization through tools like VO2 max breath testing, and what it means to turn data into something you can actually act on. Whether you're new to longevity science or already building your wellness stack, this episode will meet you where you are.If you're ready to stop guessing and start understanding what your body actually needs to thrive, this episode will give you a science-backed, practical roadmap to get there.What You'll LearnThe lifestyle habits that naturally raise NAD levels — and which ones silently deplete themWhy alcohol costs your body two NAD molecules, plus magnesium, zinc, and B1 — for every single drinkHow sleep deprivation drops NAD levels and drives up inflammationWhy intermittent fasting triggers autophagy and boosts cellular renewalThe role of muscle mass in longevity and why both aerobic and anaerobic exercise matterWhat VO2 max testing and breath analysis reveal about your metabolism and performanceConnect with AlexanderWebsite: www.nadclinic.comResources MentionedNAD Clinic — Global leader in cellular health and performance medicine; nadclinic.comPNOE — Breath analysis and VO2 max testing used by NAD Clinic for performance optimizationMethylene Blue — Mitochondrial energy tool discussed in depth in Part 1; referenced again here as part of the longevity toolkitGlobal Wellness Summit (Dubai) — Where this conversation was recordedChapters00:00 — Recap & welcome to Part 202:57 — Lifestyle habits that naturally boost NAD03:50 — Exercise, muscle mass, and mitochondrial health04:08 — How alcohol depletes NAD and key co-nutrients05:01 — Intermittent fasting and autophagy explained06:03 — Testing NAD levels and optimal ranges by gender and athlete status08:18 — IV vs. oral supplementation — which is right for you?08:43 — Inside NAD Clinic's science-based approach09:08 — VO2 max and breath analysis with PNOE10:35 — Where to start — nadclinic.com
