Common questions

What supplements are best for longevity?
The best-evidenced 'longevity' basics are unglamorous: omega-3, vitamin D, and exercise-supporting nutrients. Frontier options like NMN/NR, fisetin, and urolithin A are promising but still early in human research.
Do NAD+ supplements like NMN work?
NMN and NR reliably raise NAD+ levels in the blood, but whether that translates to living longer in humans isn't yet proven. They're reasonable to try with realistic expectations.
