| Attribute | NMN | NAD+ |
|---|---|---|
| Category | Longevity | Longevity |
| Research Stage | Preclinical | Phase II |
| Mechanism of Action | NMN functions as a direct precursor to NAD+ (nicotinamide adenine dinucleotide) through the NAD+ salvage pathway. The conversion requires a single enzymatic step catalyzed by NMNAT (nicotinamide mononucleotide adenylyltransferase), which adenylates NMN using… | Redox Cofactor Function NAD+ serves as the primary electron acceptor in catabolic reactions (glycolysis, TCA cycle, fatty acid oxidation), cycling between its oxidized (NAD+) and reduced (NADH) forms. This fundamental energy metabolism role means every cell… |
| Half-Life | — | Varies by form: NR ~8 hours plasma; NMN ~1-2 hours plasma; IV NAD+ infusion dose-dependent |
| Typical Dose Range | — | 50,000–500,000 mcg (50–500 mg) per injection; higher for IV infusions |
| Dosing Frequency | — | 2–3 times per week subcutaneous; weekly-monthly IV infusions |
| Administration | — | Oral (precursors), Intravenous, Intramuscular, Subcutaneous |
| Side Effects | NMN has a favorable short-term safety profile across tested human doses (100-1200 mg/day for up to 12 weeks in available studies). Across multiple clinical trials, no serious NMN-attributable adverse events have been reported, and commonly-reported side… | Nicotinamide Riboside (NR) NR has the best-characterized safety profile of the NAD+ precursors. Across published RCTs at 1,000-2,000 mg/day for up to 12 weeks, adverse effects have been mild and uncommon: - Gastrointestinal upset (5-10% of users) - Mild… |
| Molecular Weight | — | 663.4 g/mol (NAD+); NR 255.3 g/mol; NMN 334.2 g/mol; NAM 122.1 g/mol |
| Common Vial Sizes | — | 100mg, 250mg, 500mg |

Frequently asked
What's the difference between NMN and NAD+?
NMN is a longevity that nmn functions as a direct precursor to nad+ (nicotinamide adenine dinucleotide) through the nad+ salvage pathway. the conversion requires a single enzymatic step catalyzed by nmnat…. NAD+ is a longevity that redox cofactor function nad+ serves as the primary electron acceptor in catabolic reactions (glycolysis, tca cycle, fatty acid oxidation), cycling between its oxidized (nad+) and…. The two differ in mechanism, half-life (not reported vs Varies by form: NR ~8 hours plasma; NMN ~1-2 hours plasma; IV NAD+ infusion dose-dependent), and typical dose range.
Which has the longer half-life, NMN or NAD+?
NMN has a half-life of not reported. NAD+ has a half-life of Varies by form: NR ~8 hours plasma; NMN ~1-2 hours plasma; IV NAD+ infusion dose-dependent. Longer half-lives generally mean less frequent dosing but slower on/off kinetics.
Can you stack NMN and NAD+?
Stacking depends on mechanism overlap, safety profile, and goals. NMN and NAD+ should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data. Use the BodyHackGuide stack builder for a structured review before combining research compounds.
