Also known as: NR, Niagen reference
Nicotinamide riboside (NR) is an NAD+ precursor vitamin B3 form, converted to NAD+ via the NRK1/NRK2-mediated salvage pathway (a distinct entry point from NMN). Multiple randomized controlled human trials confirm NR supplementation reliably raises blood NAD+ metabolome levels; functional/clinical endpoint benefits (metabolic, cognitive) are more variable and depend on population and dose, mirroring the broader NAD+ precursor literature.

Reflects preclinical/research literature context only. Not a medical claim, dosing instruction, or treatment recommendation.
Amounts and schedules are separated by administration route. Evidence badges distinguish labels, human studies, preclinical work, community reports, and evidence gaps.
300-1000 mg/day in published human studies
Context: human NAD-metabolism trials
Formulation: Oral-mucosal formulations are not dose-equivalent to injectable or topical formulations.
Route safety: Research-study protocol only; it is not an approved or individualized instruction and should not be extrapolated to another route.
Do not convert an amount between routes. Bioavailability, formulation, sterility, monitoring, and clinical context differ by route. Research-use context only; independently verify every cited source.
Nicotinamide riboside raises blood NAD-related metabolites, but clinical outcome benefits are not established across indications.
Supplementary research context only. Not medical advice or a treatment recommendation.
