He and James also go deep on the practical longevity playbook: NMN, NAD and Sirtuins, metformin and berberine, testosterone and muscle mass, sleep, diet, and how to separate real science from longevity misinformation. Sinclair shares his own protocol at 56, his 86-year-old father's results, and teases a next-generation "rejuvenation in a pill" molecule his lab hopes to test in humans.
Note: Sinclair discusses early-stage, in-trial, and animal-model research. His forward-looking claims are his own and are not yet proven in humans. Nothing here is medical advice — talk to a physician before changing any supplement or medication.
In this episode:
1. How age-reversal tech reached FDA-cleared human trials, starting with the eye
2. What Yamanaka factors are and why they act as a "factory reset" for cells
3. Why three genes (OSK) reverse aging ~75% without triggering cancer
4. The built-in antibiotic "on/off" safety switch behind the therapy
5. Why reversing the age of tissue may let the body cure disease at its source
6. The realistic timeline, cost problem, and path from eye injections to a pill
7. Sinclair's take on NMN, NAD, metformin, berberine, testosterone, and sleep
8. What's next after glaucoma: liver, joints, skin, and a next-gen molecule
