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.
Based on beta-alanine studies showing significant improvements in combat sports and exercise capacity. Effects primarily through muscle pH buffering. Carnosine itself has rapid breakdown limiting direct effects.
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.
AI-estimated from published studies. Interpret as directional guidance.
