A
NAD+
B
NMN
A side-by-side look at what NAD+ and NMN actually are, so you can see where they overlap and where they genuinely differ before deciding which is worth researching further — no score, no “winner,” just the facts next to each other.
FDA status
NAD+
No FDA-approved product exists in any form
NMN
No FDA-approved drug product exists — sold as an oral dietary supplement. FDA determined in Nov. 2022 that NMN was excluded from the legal supplement definition, then reversed that determination in Sept. 2025 and formally reinstated its supplement status that December
Typical dose / use
NAD+
No standard dose — sold as injectable, nasal spray, or oral liquid, mostly subscription-priced
NMN
No standard dose — human trials tested oral doses from 250–2,000 mg/day over 14 days to 24 weeks
Product forms
NAD+
Injectable, nasal spray, or oral liquid
NMN
Oral capsule or powder
How it works
NAD+
A coenzyme central to cellular energy metabolism and DNA repair; a 2026 systematic review of 113 studies found zero eligible outcome trials for injectable/IV NAD+ itself, versus a real but mixed 28-trial literature for oral precursors.
NMN
The direct biosynthetic precursor the body's salvage pathway converts into NAD+ one metabolic step later; whether intact NMN actually crosses the gut wall after oral dosing is itself a real, unresolved scientific dispute among researchers in the field.

Every fact above is reused from NAD+'s own compound guide and NMN's own research article, not re-derived here. A highlighted value means that number is objectively larger or smaller — more providers ranked, a lower standing price — never a claim about which compound is “better.” Cost and provider counts are read live from each compound's own board and can change without notice.
