COSMOS Outcomes

Staying healthy as we age is important.

However, there is still a lot more for science to uncover on the contributors to healthy aging.

COSMOS looks to further our understanding of healthy aging, and specifically the role cocoa flavanols can play in our health.

The scale and duration of COSMOS will lead to important insights into the role that nutrition, including bioactives like flavanols, can play in heart, brain, and our general health.

The first publication from COSMOS will focus on cardiovascular health, and it will be the first of many to come
