Resveratrol and Longevity: What Research Shows

What this page covers

Resveratrol is a plant compound (a polyphenol) found in some foods and sold as a supplement. It became a longevity topic after lab work suggested it might switch on sirtuins, proteins linked to aging pathways. This page covers only that longevity research angle. For the ingredient itself, sources and general safety, see polyphenols, quercetin and resveratrol.

Evidence labels: preclinical (cells or animals only), promising but limited, mixed, insufficient evidence, no good evidence of benefit, marketing claim. Resveratrol is not an approved medicine for aging or any age-related condition; regulator status by country was not verified this session.

The animal evidence

• Lifespan in mice: not shown. The US National Institute on Aging Interventions Testing Program tests compounds in genetically varied mice at three sites. In its 2013 report, lifelong resveratrol starting at 4 months of age had no statistically significant effect on lifespan of male or female mice at the concentrations tested. [1] Label: no good evidence of benefit for lifespan in this model.
• Calorie-restriction "mimic" idea is limited. A review of mouse studies that compared resveratrol directly with calorie restriction found that, in most studies, mice given resveratrol did not show significant reductions in body weight, glucose or insulin. It said it remains unclear whether resveratrol can prolong lifespan in mammals. [2]
• Results in yeast and worms do not transfer to people.

The human evidence

Sirtuin activation. A 2025 meta-analysis of 11 randomized trials found resveratrol had no significant overall effect on human SIRT1 gene expression, protein expression or serum levels. A subgroup of shorter studies measuring blood tissue did show a rise in gene expression. [3] So the proposed mechanism is not clearly confirmed in people. A SIRT1 measurement is a biomarker, not a health outcome.

Older adults. A 2024 systematic review of 10 randomized trials in older adults found mixed results: resveratrol combined with exercise improved adaptation and muscle function in some groups, but it was not more effective than placebo in older adults with diabetes or peripheral artery disease. At high doses it increased some cardiovascular risk biomarkers in overweight people. [4] Label: mixed.

Cognition in postmenopausal women. A 24-month randomized crossover trial in 125 women aged 45 to 85 gave 75 mg of trans-resveratrol or placebo twice a day (a study amount) for 12 months each. Overall cognitive performance improved by 33% versus placebo (Cohen's d = 0.17, a small effect size), with secondary improvements in blood-flow markers. [5] It is a single trial in one population. Label: promising but limited.

Lifespan or healthspan in people: Proper evidence not found. We looked for randomized trials measuring survival or major clinical events and the reviews above contained none.

How to judge claims

A bottle saying "activates longevity genes" is a marketing claim unless it cites human outcomes. Resveratrol's animal story, the mixed sirtuin result and the null mouse lifespan study should all be weighed together. See reading longevity studies and sirtuins and NAD-dependent signaling. For side-by-side comparison, see resveratrol vs NMN vs spermidine.
