The Claim
In healthy adults aged 50–69, daily consumption of 900 mg of cocoa flavanols for 3 months likely improves dentate gyrus function, as measured by increased cerebral blood volume in the hippocampal body, and enhances performance on a pattern-separation cognitive task, with a mean reaction time improvement of 630 ms, suggesting a non-pharmacological strategy to mitigate age-related memory decline.
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.
If you're between 50 and 69 and eat a daily dose of cocoa flavanols for three months, you might get better at remembering small differences between similar things—and your brain’s memory area might get more blood flow, helping fight off some of the memory slowdown that comes with aging.

What the research says
1 studyStudy: Enhancing dentate gyrus function with dietary flavanols improves cognition in older adults
The study gave older adults a cocoa drink rich in certain plant compounds for three months and found they got better at remembering small differences between similar things, and their brain activity in the memory area improved — just like the claim says.
