Nicotinamide mononucleotide (NMN) is a naturally occurring nucleotide derived from vitamin B3 (niacin) and a direct biosynthetic precursor to nicotinamide adenine dinucleotide (NAD⁺). NAD⁺ is a coenzyme present in every living cell, where it shuttles electrons during cellular respiration and serves as an essential cofactor for enzymes that govern energy metabolism, DNA repair, and gene expression. Once ingested, NMN is converted to NAD⁺ through the salvage pathway, helping to replenish the cellular NAD⁺ pool.
Tissue NAD⁺ concentrations decline substantially with age across human skin, blood, liver, muscle and brain. Because NAD⁺ is the obligatory fuel for the sirtuin family of longevity enzymes and for PARP-mediated DNA repair, this decline is considered one of the proposed drivers of cellular aging. Restoring NAD⁺ with NMN is therefore studied as a way to support mitochondrial function, DNA-repair capacity and sirtuin activity — the cellular machinery most closely tied to healthspan.
Peer-reviewed studies on the active compound — citations link to PubMed.
“In animal studies, β-nicotinamide mononucleotide (NMN) supplementation increases nicotinamide adenine dinucleotide (NAD) concentrations and improves healthspan and lifespan with great safety.”
“As the NAD concentration in human skin, blood, liver, muscle, and brain are thought to decrease with age, finding ways to increase NAD status could possibly influence the aging process.”
“Caloric restriction has been shown repeatedly to prolong the lifespan in laboratory animals, with its benefits dependent on molecular targets... including the NAD-dependent deacetylase SIRT1.”
“NMN supplementation showed potential in alleviating arterial stiffness”
“Physical-performance improvements from NMN tracked the rise in blood NAD+, with benefit maximized around 600 mg/day in a dose-dependent trial.”
