Alexander Audit | Chief Scientific Officer | NAD Clinic

Alexander 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 Learn

• The lifestyle habits that naturally raise NAD levels — and which ones silently deplete them
• Why alcohol costs your body two NAD molecules, plus magnesium, zinc, and B1 — for every single drink
• How sleep deprivation drops NAD levels and drives up inflammation
• Why intermittent fasting triggers autophagy and boosts cellular renewal
• The role of muscle mass in longevity and why both aerobic and anaerobic exercise matter
• What VO2 max testing and breath analysis reveal about your metabolism and performance
