Arterial stiffness, cognition, and equol: a trial to help aging adults

Official title: Arterial Stiffness, Cognition, and Equol (ACE)

Funded at University of Pittsburgh at Pittsburgh · NIH-11519686 · Data updated 2026-11-12

A large, multi-site study tests whether taking equol daily for two years can slow arterial stiffness, brain changes, and thinking difficulties in older adults without dementia.

Who could benefit from this research

Could help

Ideal candidates are adults 65-85 without dementia who are willing to take daily equol and undergo regular assessments.

Less likely to help

Individuals with established dementia or significant medical contraindications may not benefit.

What this research studies

This trial involves adults aged 65-85 without dementia and looks at how a 24-month 10 mg/day equol supplement affects blood vessel stiffness, brain white matter changes, and cognitive decline. It is an IND-regulated randomized controlled trial conducted at multiple centers, with careful clinical monitoring to ensure safety and data quality. The study relies on standard clinical procedures and imaging to measure outcomes, and it requires ongoing oversight from an external CRO to stay compliant with regulatory standards. Participants would be monitored for adverse events and followed to see if equol influences vascular and cognitive trajectories.

Why it matters

Potential benefit: If successful, the approach could slow vascular-related brain aging and cognitive decline in older adults.

How similar studies have gone: Previous collaboration in similar vascular and cognitive studies suggests potential benefits, though this exact approach is novel.
