Evidence notes
Cocoa flavanols have substantial RCT evidence for cardiovascular and endothelial benefits. Effects on cognition are promising but more moderate. Evidence is strongest for high-flavanol extracts; plain cocoa powder is less standardized.
Grade B: Some human trials support key claims; further confirmation needed.
