What are the proven health benefits of beetroot juice?
Quick answer
Beetroot juice is one of the most-studied natural foods. Daily 250–500ml lowers blood pressure (5–10mmHg systolic in trials), improves exercise endurance via the dietary nitrates → nitric oxide pathway, and provides betalain antioxidants. The blood-pressure effect is consistent and clinically meaningful.
Beetroot has some of the strongest scientific evidence of any juice ingredient. It is rich in dietary nitrates, which the body converts to nitric oxide — a molecule that dilates blood vessels and improves blood flow. A major meta-analysis confirmed that beetroot juice supplementation reduces systolic blood pressure by an average of 4.4 mmHg. It also significantly improves athletic endurance and cardiorespiratory performance.
