Effect of resveratrol supplementation on biomarkers associated with atherosclerosis in humans
PMID: 34731768 2022 系統性回顧
Finding: Higher doses (~454 mg/day) for shorter durations produced greater TG and BP reductions; lower doses (~274 mg/day) for longer durations (175 days) produced the highest HDL increase; results dose- and duration-dependent with high heterogeneity.

Study results on resveratrol are mixed — some research shows that resveratrol may reduce blood clots and inflammation to lower heart disease risk, but other studies have found that resveratrol does not protect against heart disease, and more research is needed. Research suggests that the body can't absorb most of the resveratrol in supplements. source↗
