NMN reverses aging
The evidence
Human randomized trials show only that blood NAD+ levels rise; there are zero data on the outcomes that matter, lifespan or healthy lifespan.
Why the claim spreads
Backed by charismatic longevity researchers and animal data; 'a molecule that reverses aging' is the ultimate aspirational pitch.
The mechanism, in brief
NMN and NR are two raw materials the body uses to make NAD⁺, and in recent years they have been sold as anti-aging supplements. NAD⁺ is one of the busiest molecules in the cell: it picks up electrons released by metabolism and carries them into the mitochondria to make energy (dive to niacin-b3). It also has a second…
