Clinical Trial Summary

to assess the effect of differing amounts of a cocoa-derived dietary flavanol (epicatechin ) on dentate gyrus function and corresponding cognitive function


Clinical Trial Description

In this double blinded trial, the participants, age 50-75 years, will be randomized to receive 0, 260, 510, or 770 mg daily* for 12 weeks and will be tested before and after the intervention. Cognitive testing will be conducted prior to randomization, and at weeks 4, 12, and 20 of the study.

In an optional substudy, fMRI (functional magnetic resonance imaging) with gadolinium contrast will be conducted to measure dentate gyrus function before randomization and then after completion of the 12-week intervention portion of the trial.
