The Claim
In overweight older adults, resveratrol supplementation at doses of 150–500 mg/day for 8–24 weeks improves cognitive function scores without consistently improving metabolic markers.
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 overweight older adults, taking resveratrol supplements for 8 to 24 weeks leads to improved cognitive test scores but does not consistently change metabolic markers such as insulin sensitivity or fat metabolism.
See the scientific wording
In overweight older adults, resveratrol supplementation (150–500 mg/day for 8–24 weeks) improves cognitive function scores, but does not consistently improve metabolic markers, indicating a condition-specific benefit on cognition independent of weight loss or insulin sensitivity.
Resveratrol activates a protein in brain cells that boosts the number and efficiency of energy factories inside neurons, which improves blood flow to the brain and helps brain cells work better, leading to sharper thinking and memory.
What the research says
1 studyStudy: Effects and safety of resveratrol supplementation in older adults: A comprehensive systematic review
In older adults who are overweight, taking resveratrol pills may help them think and remember better, even if it doesn’t help with blood sugar or weight loss — and that’s exactly what the study found.
