The Claim

High-dose resveratrol supplementation (≥500 mg/day) in older adults is associated with increased levels of biomarkers of cardiovascular disease risk, including LDL cholesterol and inflammatory markers.

In plain English

Taking 500 mg or more of resveratrol daily in older adults is linked to higher levels of LDL cholesterol and inflammatory markers, which are indicators of increased cardiovascular disease risk.

See the scientific wording

High-dose resveratrol supplementation (≥500 mg/day) in older adults may increase biomarkers of cardiovascular disease risk, such as LDL cholesterol or inflammatory markers, suggesting potential harm at elevated doses despite overall safety.

Why this might work

High doses of resveratrol overload the liver's ability to process fats, causing it to produce more bad cholesterol and trigger inflammation in the bloodstream.

  1. Study: Effects and safety of resveratrol supplementation in older adults: A comprehensive systematic review

    Taking very high doses of resveratrol (500 mg or more) may raise blood markers linked to heart disease risk, even though it doesn’t cause obvious side effects — and this study found exactly that in older adults.
