Clinically dosed — the label discloses at least as much NMN per serving as clinical trials used. The black tick on the bar marks the trial dose.
Under clinical dose — the label is honest about the amount, but it's less than the studies used, so the studied effect may not apply.
Dose not disclosed — the label doesn't let you verify the amount at all (usually a "proprietary blend" that only prints the mixture's total weight).
Data verified 2026-07-18 · Scored against: NMN dose-dependent RCT (Yi et al. 2022, GeroScience): oral NMN raised blood NAD+ dose-dependently across 300/600/900 mg/day over 60 days; physical-performance benefit peaked at 600 mg. We use 300 mg (the lowest studied dose that significantly raised NAD+, the lower bound of the effective range). NAD+ elevation is a biomarker: 'sufficient' means meeting the NAD+-raising studied dose, not a proven clinical/longevity outcome.. How scoring works →

No — the label discloses 250 mg of NMN per serving, below the 300 mg/day clinical dose. You'd need more than one serving to match the studied amount.
Clinically dosed, no-blend options include: California Gold Nutrition NMN 300 mg (300 mg); Doctor's Best NMN + CoQ10 (300 mg); Dr. Emil Nutrition NMN 400 mg (400 mg). All disclose at least 300 mg per serving on the label.
