First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This completed study tested whether drinking beetroot juice (rich in nitrate) could reduce the strain on the heart and blood vessels caused by caffeine and cold exposure. Twenty-four healthy adults took beetroot powder, caffeine, and a cold foot bath while researchers measured blood pressure and artery function. The goal was to see if a simple dietary supplement could help the cardiovascular system handle everyday stressors better.
