Hypertension
The Acute Effect of Beetroot Juice in Normal and Hypertensive Subjects
Inorganic nitrate can be converted to nitrite and thence nitric oxide in humans. Nitric oxide is normally produced by the inner lining of blood vessels and helps keep blood vessels open and therefore blood pressure lower.
