Resveratrol vs NMN
Written by Aaron CuhaReviewed Sep 2026
The short answer
The two halves of the stack David Sinclair has described taking. One is claimed to switch on sirtuins, and the other is an NAD+ building block. Both have human trials. Neither has a lifespan result or any hard health result, and the pair together has never been tested in a trial.

First-hand reports are counted on each profile and never added together. This page sets two published records side by side. It does not pick a winner.
Column A
ResveratrolResveratrol (trans-3,5,4'-trihydroxystilbene)
Resveratrol is the grape and red wine compound behind the first big wave of anti-ageing research. It is one of the most tested supplements on this site, with over 150 finished registered studies. The results conflict, and they split by who took it and how much, rather than pointing one way. No trial in people has measured lifespan or any hard health result like heart attacks or death.
Column B
NMNNicotinamide Mononucleotide
A pill the body turns into NAD+. It is studied for blood sugar and strength in ageing. Early studies in people show small results, and whether it can be sold as a US supplement is disputed.
Side by side, on the facts we can check
| What we compare | Resveratrol | NMN |
|---|---|---|
| Category | Longevity | Longevity |
| FDA status | Dietary supplement; not an approved drug. Labels may say how it supports the body, with the disclaimer the US supplement law requires, but may not claim to treat or prevent a disease | Not an approved drug; whether it can be sold as a US supplement is disputed |
| Half-life | About 9 hours for resveratrol plus its sulfate and glucuronide conjugates after an oral dose; free parent compound is cleared far faster | Short |
| Molecular weight | 228.24 Da | 334.2 Da |
| How it works | The main idea is that resveratrol switches on SIRT1, an enzyme that needs NAD+ to work. That in turn sets off signals, AMPK and PGC-1alpha, that copy parts of eating less. That claim is disputed. Teams at Amgen (2009) and Pfizer (2010) showed the switch-on only happened with a glowing tag stuck to the test protein. It vanished with natural proteins. Sirtris and Sinclair's group answered in Science (2013). They argued the switch-on is real, but only with target proteins that carry certain water-avoiding patches, plus one spot on SIRT1, Glu230. Apart from sirtuins, resveratrol is a known antioxidant. It helps blood vessels widen through nitric oxide. And at gram doses it blocks the liver enzymes CYP3A4, CYP2D6 and CYP2C9, which break down many prescription drugs. | The body turns it into NAD+ through a recycling route called the salvage pathway. The aim is to bring back NAD+ levels that fall with age. |
| Studies in people | 14 | 4 |
| Evidence | Moderate: 14 completed trials, 403 people given it | Limited: 4 completed trials, 94 people given it |
| Legal status, US | Sold as a dietary supplement; not an approved drug | Not approved; in 2022 the FDA decided it does not count as a supplement |
Frequently asked questions
What is the difference between Resveratrol and NMN?
Resveratrol: Resveratrol is the grape and red wine compound behind the first big wave of anti-ageing research. It is one of the most tested supplements on this site, with over 150 finished registered studies. The results conflict, and they split by who took it and how much, rather than pointing one way. No trial in people has measured lifespan or any hard health result like heart attacks or death. NMN: A pill the body turns into NAD+. It is studied for blood sugar and strength in ageing. Early studies in people show small results, and whether it can be sold as a US supplement is disputed.
Which has stronger research evidence, Resveratrol or NMN?
Each compound gets a band worked out from facts we counted, with the math shown. Resveratrol is Moderate (14 completed trials, 403 people given it). NMN is Limited (4 completed trials, 94 people given it). That counts how much has been done in people. It does not rate whether either one works, and neither one is called the winner.
Are Resveratrol and NMN FDA-approved?
Resveratrol: Dietary supplement; not an approved drug. Labels may say how it supports the body, with the disclaimer the US supplement law requires, but may not claim to treat or prevent a disease. NMN: Not an approved drug; whether it can be sold as a US supplement is disputed.
