Nicotinamide Mononucleotide
NAD+ precursor backed by strong clinical evidence for boosting cellular energy and supporting healthy aging.
What the evidence says
NMN appears to help in 5 of 6 studies with measurable effects — the evidence leans clearly favourable.
Most evidence is from high-quality meta-analyses and randomised trials published 2020–2026 with a typical study size of 48 participants.
Based on 27 studies · 4 meta-analyses · 19 RCTs · 3,349 total participants
Confidence
HighWhat the studies found
By outcome
NMN has an evidence score of 8.5/10 — very strong evidence based on 25 indexed studies, including 6 meta-analyses. NAD+ precursor backed by strong clinical evidence for boosting cellular energy and supporting healthy aging.
The commonly studied dose of NMN is 250-500mg. Research points to an estimated optimal dose around 500mg, with a minimum effective dose near 250mg. Individual response varies — start low and adjust.
The best time to take NMN is in the morning. Taking it with food is preferred. NMN (nicotinamide mononucleotide) is a direct NAD+ precursor.

NMN (Nicotinamide Mononucleotide) is a precursor to NAD+, a coenzyme essential for cellular energy production and DNA repair that declines with age. Multiple RCTs and meta-analyses demonstrate that NMN supplementation effectively raises NAD+ levels in humans, with growing evidence for improvements in metabolic health, exercise capacity, and biological markers of aging. Competes with NR (Nicotinamide Riboside) as a NAD+ boosting strategy.

NMN is the direct biosynthetic precursor to NAD+ (one step closer than NR); NR and NMN share overlapping but distinct conversion pathways. They may be complementary at lower doses of each rather than stacking high doses.

NMN is generally safe at recommended doses, with a few precautions worth noting. The most commonly reported side effects are flushing (rare), mild GI upset. Use caution if any of these apply to you: Cancer (theoretical concern about fueling cancer cell metabolism).
