Grape extract and exercise: a natural combo for blood pressure?
NCT ID NCT06985407
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether taking grape extract, a supplement rich in polyphenols, could improve blood pressure and blood vessel function after exercise in people with slightly high blood pressure (prehypertension). Ten sedentary adults took either grape extract or a placebo for a week, then switched after a break. Researchers measured blood pressure and artery function right after exercise and over 24 hours. The goal was to see if the combination works better than exercise alone.

What this could lead to
