Cocoa extract supplement given to elderly with lower diet quality may improve their cognitive function: Study

The findings from this study which was done among COSMOS participants who presented in person for detailed cognitive testing-are consistent with the results from an earlier study that used a web-based cognitive assessment given over the internet to a separately recruited set of COSMOS participants.

COSMOS is an investigator-initiated large-scale, long-term clinical trial led by Brigham and Women’s Hospital. More than 21,000 older women and men were enrolled across the United States to participate in this randomized, double-blinded, placebo-controlled study to test whether taking daily supplements of a cocoa extract or a common multivitamin reduces the risk for developing heart disease, stroke, cancer, and other important health outcomes. Analyses of the data from COSMOS continue to yield insights about the connections between supplements and human health.
