NMN (nicotinamide mononucleotide) is a direct precursor to NAD⁺, a coenzyme that declines with age. Here are the NMN products we grade highest on evidence and quality, with the research behind them.
Browse NAD⁺ & NMN products →NAD⁺ powers cellular energy and DNA repair and falls with age; NMN is one step away from NAD⁺ in the salvage pathway. When choosing an NMN supplement, the things that matter are purity (third-party tested, ≥99%), dose (trials typically use 250–900 mg/day), and delivery (some use liposomal forms). Read the NAD⁺ research for the human trials.

The best NMN is one that is third-party tested for purity (≥99%), dosed in the studied range (250–900 mg/day), and from a transparent brand. Each NMN product here is graded on evidence and links to its research.
NMN reliably raises NAD⁺ in humans in trials; effects on hard aging outcomes are still being studied. The product pages link to the current human evidence.
Both raise NAD⁺. NR (nicotinamide riboside) has more human trial data; NMN is one step closer to NAD⁺. Evidence is still evolving for both.
Human trials commonly use 250–900 mg per day. Start low and discuss with your physician, especially if you take medication.
