Fresh or concentrated beetroot yields this liquid, rich in nitrates. The juice converts to nitric oxide in the body, enhancing blood flow, exercise stamina, and blood pressure balance unlike powders or extracts.
Take 300 to 500 mL on an empty stomach 2 to 3 hours before physical activity. Some people drink it each morning for cardiovascular health. The right dose depends on concentration and personal tolerance.
Oxalates in beet juice can lead to kidney stones in susceptible individuals. The drop in blood pressure may pose risks if you take antihypertensive medication. In rare cases, very large amounts might cause methemoglobinemia from nitrate conversion.
