Cocoa extract slows inflammation in older adults

Researchers at Mass General Brigham report that in a randomized substudy of the COSMOS trial nearly 600 adults (average age ~70) who took 500 mg of cocoa extract daily for two years showed an 8.4% slower annual increase in high-sensitivity C-reactive protein (hsCRP) compared with placebo. The peer-reviewed findings, published this month in Age and Ageing, suggest cocoa flavanols may help reduce low-level chronic inflammation ('inflammaging') linked to cardiovascular and other age-related diseases, though authors caution more research is needed to tie biomarker changes to clinical outcomes.

Cocoa extract could slow aging process in older adults, 'promising' new study finds
Fox News September 27, 2025
New information:
  • Study population: nearly 600 participants with mean age about 70 enrolled in a two-year randomized substudy of COSMOS
  • Intervention: 500 mg cocoa-extract capsule daily versus placebo for two years
  • Primary numeric result: 8.4% slower annual increase in hsCRP among those taking cocoa extract; earlier COSMOS analyses linked cocoa flavanols to a 27% lower cardiovascular disease death
