In this episode of The Human Upgrade, Dave Asprey and Dr. Andrew Salzman (Chief Medical Officer of Wonderfeel) dive deep into NAD—the molecule that fuels energy, repairs DNA, and slows aging. As NAD levels decline with age, it accelerates fatigue, brain fog, and disease, but Dr. Salzman reveals the fastest, most effective ways to restore it. From cutting-edge NAD supplements to CD38 inhibitors that prevent its depletion, this episode unpacks the next generation of longevity science and how you can harness it to stay energized, sharp, and resilient for decades to come.
Could a single molecule be the difference between vibrant longevity and early decline?
Dr. Andrew Salzman—Harvard-trained physician, scientist, and creator of the first PARP1 inhibitor, Chief Medical Officer of Wonderfeel—joins Dave to reveal the real key to living longer, fighting disease, and maximizing your energy: NAD.
This master molecule fuels your mitochondria, DNA repair, and cellular resilience, but here’s the catch—it plummets as you age. That means more fatigue, brain fog, inflammation, and higher risks of disease. But what if you could stop the decline and even reverse it?
Dr. Salzman breaks down the game-changing science behind NAD, CD38, and cellular repair—and the fastest, most effective ways to optimize your levels for peak performance, health, and longevity.
Get ready to rethink everything you thought you knew about aging, pharmaceuticals vs. supplements, and the radical new approach to living better, longer.
