Summary

Beetroot and other nitrate-rich foods provide inorganic nitrate that is converted to nitric oxide, supporting vasodilation, blood flow, and mitochondrial efficiency. This underlies its use for blood pressure support and as an ergogenic aid for endurance and high-intensity exercise. Effects are dose-dependent and can add to the action of blood pressure medications.
