Resveratrol is a polyphenol compound found in red grapes, berries, and red wine. Researchers have studied it extensively for its antioxidant properties. People often choose it to support cardiovascular health and maintain blood sugar within the normal range.
Most users take resveratrol as a capsule or tablet with a fat-containing meal to improve absorption. Anti-aging and multivitamin formulas sometimes include it too.
Heads up: mild antiplatelet effects mean it could interact with blood thinners like warfarin. Its weak estrogen-like activity calls for caution in those with hormone-sensitive conditions. Higher doses may cause mild digestive discomfort for some people.
