The Claim
Cocoa flavanols significantly increase cerebral blood flow, particularly to the dentate gyrus, a region critical for memory formation.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Eating cocoa with flavanols might boost blood flow to a part of your brain that helps you form memories, like when you're trying to remember names or facts.

Cocoa flavanols significantly increase cerebral blood flow, particularly to the dentate gyrus, a region critical for memory formation.
What the research says
2 studiesThis study found that drinking a special cocoa drink with lots of flavanols made more blood flow to parts of the brain in older adults, which is exactly what the claim says cocoa flavanols do — even though it didn’t check the exact memory area called the dentate gyrus.
Study: Enhancing dentate gyrus function with dietary flavanols improves cognition in older adults
Scientists gave older adults chocolate with lots of cocoa flavanols for 3 months and found their memory-related brain area worked better — which means the chocolate likely helped increase blood flow to that area.
