Reverse Aging with NMN: The Science of Youthful NAD Boosters Explained by Dr David Sinclair 2026

We will not just slow aging but we will reverse the aging process. And this is an example. Now NAD boosters get you your youthful levels of NAD and we think fight back. So some of the evidence comes from mice. These are 20-month-olds mice. Sorry about the black mice on a black treadmill. But one of these mice clearly is fitter than the other one and it's the one that's been drinking NMN in its water. And what we traced this to was that the cert one enzyme, the certuin in the lining of the blood vessels was responsible and it was mimicking the effects of exercise. And that's why these untrained mice now ran multi-arathons and in fact ran so far that the machine stopped running and we had to rewrite the software because the software didn't anticipate mice running over 3 kilometers.
