Origin & tradition
NMN is not a traditional remedy but a modern molecule at the center of the NAD+ longevity field studied at Harvard and Washington University. NAD+, the coenzyme it feeds, declines with age.

The headline NAD+ booster of the longevity world — human trials show it raises blood NAD+ and may support physical function.
NMN is not a traditional remedy but a modern molecule at the center of the NAD+ longevity field studied at Harvard and Washington University. NAD+, the coenzyme it feeds, declines with age.
Key active: Nicotinamide mononucleotide (NAD+ precursor).
NMN is a direct precursor to NAD+, the coenzyme that fuels mitochondrial energy and sirtuin activity and declines with age. A 2022 randomized, placebo-controlled trial in healthy middle-aged adults found dose-dependent increases in blood NAD+ and improved six-minute walking distance.
