Clinically dosed — the label discloses at least as much Nicotinamide Riboside 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: Nicotinamide riboside (Niagen) dose-response RCT (Conze et al. 2019, Sci Rep): 300 mg/day raised whole-blood NAD+ ~51% over 8 weeks (dose-dependent across 100/300/1000 mg); 300 mg is the studied and Tru Niagen label dose. NAD+ elevation is a biomarker: 'sufficient' means meeting the NAD+-raising studied dose, not a proven clinical outcome.. How scoring works →
