Evidence for longevity
NMN (Nicotinamide Mononucleotide)
30%Animal studies show promising anti-aging effects, but human longevity data is essentially absent. NAD+ boosting is mechanistically plausible but unproven for lifespan extension.
Resveratrol
25%Strong preclinical evidence in animal models but no convincing human data demonstrating lifespan extension or meaningful aging biomarker improvements at achievable doses.
Mechanism of Action
NMN (Nicotinamide Mononucleotide)
NMN is converted to NAD+ through the enzyme NMNAT (nicotinamide mononucleotide adenylyltransferase). Elevated NAD+ levels activate sirtuins (SIRT1-7), a family of deacetylase enzymes involved in DNA repair, mitochondrial biogenesis, inflammation control, and circadian rhythm regulation. NAD+ also se...
Read full review →Resveratrol
Resveratrol activates SIRT1, a NAD-dependent deacetylase linked to cellular stress resistance and metabolic regulation, mimicking some aspects of caloric restriction. It also activates AMPK signaling, improves mitochondrial function, reduces NF-kB mediated inflammation, and inhibits platelet aggrega...

NMN (Nicotinamide Mononucleotide)
NAD+ levels rising in blood. Intracellular effects beginning.
Energy and exercise capacity may improve in older adults. Limited human data.
Longevity biomarkers unproven in humans. Animal data promising but not yet translatable.
Long-term human safety and efficacy still being established. NRCT trial ongoing.
Resveratrol
Resveratrol absorbed but rapid metabolism limits bioavailability significantly.
Modest anti-inflammatory effects possible. No lifespan data in humans.
Blood flow and endothelial function may show slight improvement.
Long-term benefits remain unproven in humans despite strong animal data.
🤝 Can You Take Both?
✅ These can generally be taken together safely. Many people stack both for complementary effects.
However, always start one at a time so you can identify which is responsible for any effects you notice.
📋 The Bottom Line
Choose NMN (Nicotinamide Mononucleotide) if:
- ✓ middle-aged and older adults concerned about aging
- ✓ those with measurably low NAD+ levels
Choose Resveratrol if:
- ✓ individuals interested in longevity optimization as part of a broader strategy
- ✓ those with elevated inflammatory markers
- ✓ people seeking additional polyphenol intake
