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.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.
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.
What the research says
1 studyThis 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.
