The Claim
Daily supplementation with 150 mg of trans-resveratrol for 24 months significantly reduced fasting insulin levels by 17.4% and improved the insulin resistance index 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 lowered fasting insulin levels by 17.4% and improved the insulin resistance index.
See the scientific wording
In postmenopausal women aged 45–85, daily supplementation with 150 mg of trans-resveratrol for 24 months significantly reduced fasting insulin levels by 17.4% (Cohen’s d = 0.174, P = 0.025) and improved insulin resistance index (Cohen’s d = 0.102, P = 0.034), indicating enhanced insulin sensitivity.
Resveratrol turns on two key cellular sensors, SIRT1 and AMPK, which signal muscle and fat cells to pull more sugar from the blood. This lowers the amount of insulin the body needs to produce to keep blood sugar stable.
What the research says
1 studyThis study gave postmenopausal women 150 mg of resveratrol every day for two years and found their insulin levels dropped by 17.4%, meaning their bodies handled sugar better. This matches exactly what the claim says.
