NMN vs Resveratrol — what is the difference?
NMN (Nicotinamide Mononucleotide) and trans-Resveratrol are the two most-discussed longevity supplements, but they work on different parts of the same biological pathway. NMN directly raises NAD+ levels. Resveratrol activates sirtuins, the enzymes that use NAD+ to do cellular repair work. They are complementary, not competing.
Side-by-side comparison
| Aspect | NMN | Resveratrol |
|---|---|---|
| Mechanism | Direct NAD+ precursor | Sirtuin activator (SIRT1) |
| Best clinical dose | 250-600mg/day (500mg most studied) | 250-500mg/day trans-Resveratrol |
| Bioavailability | Good orally (sublingual marginal benefit) | Low; needs fat for absorption |
| Strongest evidence | Yoshino 2021, Igarashi 2022 (human trials) | Smoliga 2011 (review of mixed results) |
| NZ availability | WIIP NMN Boost+, NZ-made, transparent labelling | Imported, varies in trans-form purity |
| Side effect profile | Very clean, mild GI in rare cases | Possible GI upset, drug interactions (statins) |
Should you take both?
Current best practice in longevity research: NMN alone, or NMN + small dose trans-Resveratrol (250-500mg). NMN does the heavy lifting; Resveratrol may add modest synergy but isn’t essential. If budget is limited, start with NMN.
