NCT ID NCT05232669
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether taking cocoa extract or a daily multivitamin can reduce falls and improve physical performance in older adults. Over 21,000 men and women aged 60 and older are participating. Researchers are tracking falls that require medical care and repeated falls to see if these supplements make a difference.
