Here are the NMN products we grade highest on evidence and quality, with the research behind them.* ## What NMN is, and what to look for 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).

Most trials run 6–12 weeks. - **Dose from food:** Only trace amounts in food: edamame, broccoli and avocado supply roughly 0.25–1.9 mg per 100 g. You'd need dozens of pounds to match a single 250–600 mg dose, so diet can't reach studied levels. - **What the grade does not say:** Oral NMN reliably raises blood NAD⁺ and has been well tolerated in trials up to about 900–1,250 mg/day. Functional benefits so far are modest and population-specific (muscle insulin sensitivity in prediabetic women, aerobic capacity, walking speed, sleep quality), several meta-analyses are null for glucose, lipids and muscle mass, and no trial shows effects on aging, disease prevention, or lifespan. ### Nutricost NMN Capsules 500mg - **Evidence grade:** Moderate evidence - **Dose used in studies:** Human RCTs used 250–1,200 mg/day orally; well-tolerated up to ~900 mg/day, with one dose-finding trial reporting benefits peaking near 600 mg/day.

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. ### Does NMN actually work? 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. ### NMN vs NR — which is better? Both raise NAD⁺. NR (nicotinamide riboside) has more human trial data; NMN is one step closer to NAD⁺. Evidence is still evolving for both. ### What dose of NMN should I take? Human trials commonly use 250–900 mg per day. Start low and discuss with your physician, especially if you take medication. ## The research behind these picks Primary peer-reviewed sources for the products above.
