Why do so many people lose their energy in their 40s, and what would it look like to prevent that decades earlier? In this episode, Dr. Lauren Leiva talks with Dr. Jin-Xiong She, Founder of Jinfiniti Precision Medicine and bestselling author of The Tao of NAD, about the real foundations of energy, longevity, and healthspan. Known as the "King of NAD," Dr. She talks about NAD in the most practical way: it's the molecule your cells need to function, recover, think clearly, and age slowly. Dr. She believes most people start supplementing NAD 20–30 years too late. This conversation blends ancient Taoist wisdom with modern biomarkers and precision medicine, giving you a clear, practical roadmap for extending your healthy years, not just your total years. What you'll learn: why NAD levels drop with age and how to rebuild them before symptoms show; how much vitamin D most people actually need based on data and biomarkers rather than guesses; why longevity starts before pregnancy and continues through every life stage as part of your long-term healthspan strategy; how simple, affordable habits make up 80% of your healthspan and energy optimization; why balanced nutrition and whole foods (not strict labels) support long-term vitality and anti-aging, and how ancient Taoist principles can simplify your longevity routine. Whether you're optimizing your energy levels, planning for the future with NAD supplementation, reversing aging, or rebuilding your foundation for better health, this episode gives you clear, grounded steps you can use today for sustainable wellness.
