NCT ID NCT06598488
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether drinking beetroot juice for a short time could improve heart health in 14 postmenopausal women. The juice is rich in natural nitrates that help blood vessels relax. Researchers measured blood pressure and oxygen use during rest and exercise. The goal was to find a simple, drug-free way to support heart function after menopause.
