Impact of flavan-3-ols on blood pressure and endothelial function in diverse populations: a systematic review and meta-analysis of randomized controlled trials
European journal of preventive cardiology (2025) · Meta analysis · n=5205
Flavan-3-ol interventions included epicatechin, epigallocatechin-gallate, cocoa products, tea, grape extract, and apples delivering 586 mg (95% CI 510, 662) total flavan-3-ols.
Meta-analysis of 1461 subjects showed 2.85% median improvement. Effect size 0.39 overall, with optimal effects at 5.6-6.4g/day. Most effective for 1-4 minute high-intensity efforts. Side effect risk primarily reflects paresthesia (tingling), which is common but harmless.
Based on meta-analysis showing FMD improvements with flavan-3-ol interventions. Most studies used cocoa products rather than pure epicatechin. Conservative estimate given mixed study designs and populations.
