Frequently Asked Questions

Does NAD+ really decline with age?
Yes. Massudi 2012 — NAD+ levels in human skin drop ~50% from age 20 to 60. Mechanism implicated in many age-related decline pathways. The question is whether RAISING NAD+ via supplementation translates to outcomes humans care about (lifespan, healthspan, function). That part is unproven.
Why is NMN/NR evidence so weak?
Animal studies (mice) show robust effects: longer lifespan, better mitochondrial function, etc. Human trials so far: NMN/NR DOES raise NAD+ blood levels. But translating to clinical outcomes (memory, fitness, biomarkers) — small effects or null. We need 5-10 more years of well-designed RCTs.
David Sinclair / Tru Niagen / TIME Health — what about them?
Sinclair has financial interest in NMN companies. Many "NAD+ longevity" claims are extrapolated from preclinical data. Tru Niagen / Niagen IS the only NR supplement with real human trials. Effects: real but modest. Worth $50-80/mo? Probably not for most people.
