Bottom line

Read Off Label grades Cocoa flavanols (Theobroma cacao) as A- (7.7/10) based on strong evidence, low-med benefit magnitude, and a low-risk safety profile.

COSMOS (n=21,442) is the largest cocoa flavanol RCT — missed its primary CV composite endpoint but showed ~27% reduction in CV death (secondary).

Studied, labeled, or reported-use context: 500-900 mg cocoa flavanols/day (e. — OTC; not individualized guidance.

What the evidence says

COSMOS (n=21,442) is the largest cocoa flavanol RCT — missed its primary CV composite endpoint but showed ~27% reduction in CV death (secondary). COSMOS-Mind suggested cognitive benefit in subgroups. Real but small effect; needs a standardized extract to deliver dose. Eating squares of dark chocolate doesn't reliably hit therapeutic flavanol intake.

Mechanism

(-)-Epicatechin and procyanidin B2; activate endothelial nitric oxide synthase (eNOS), improve flow-mediated dilation; mild BP reduction; possible hippocampal vascular effects

Studied, labeled, or reported dose & route

500-900 mg cocoa flavanols/day (e.g. CocoaVia at 500 mg per scoop); standardized extracts provide more consistent flavanol exposure than retail dark chocolate

This records doses and routes described in studies, approved labeling, clinical practice, or documented use. It is not individualized guidance and does not establish safety; context changes with indication, formulation, health history, monitoring, and other medicines.
