The question

Does resveratrol extend lifespan in mammals or relate to longevity in humans?

Study design

Mouse studies (2006, 2008), the NIA Interventions Testing Program across three sites (2011), and a 9-year cohort of 783 older Italians measuring urinary resveratrol (2014). ^[1][2][3][4]

What they found

Resveratrol improved health and survival in mice on a high-calorie diet. In mice on a standard diet, it improved some age-related measures without extending lifespan. The NIA program found that resveratrol did not extend lifespan in genetically diverse mice. In older Italians, dietary resveratrol levels were not associated with mortality, inflammation, cancer or heart disease. ^[1][2][3][4]

Limitations

Dietary levels in the cohort are far lower than supplement doses. Oral resveratrol has low bioavailability.

What this does not mean

This does not show that resveratrol is harmful. It shows the longevity case is unproven.
