The Claim

Daily supplementation with 150 mg of trans-resveratrol for 24 months significantly improved overall cognitive performance by 33% (Cohen’s d = 0.170, P = 0.005) in postmenopausal women aged 45–85.

Cause and effect

In plain English

In postmenopausal women aged 45–85, taking 150 mg of trans-resveratrol daily for two years resulted in a 33% improvement in overall cognitive performance.

See the scientific wording

In postmenopausal women aged 45–85, daily supplementation with 150 mg of trans-resveratrol for 24 months significantly improved overall cognitive performance by 33% (Cohen’s d = 0.170, P = 0.005), suggesting a direct benefit on brain function in this population.

Why this might work

Resveratrol activates a protein that turns on another protein in blood vessel walls, which makes more of a gas that opens up brain blood vessels. This lets more blood flow into the brain, giving brain cells more oxygen and fuel to work better, which improves memory and thinking.

  1. Study: Long-term effects of resveratrol on cognition, cerebrovascular function and cardio-metabolic markers in postmenopausal women: A 24-month randomised, double-blind, placebo-controlled, crossover study.

    This study found that taking 150 mg of resveratrol every day for two years helped older women think and remember better, just like the claim said. The women who took it did significantly better on memory tests than when they took a dummy pill.
