Our Members Asked:
Can beetroot juice or supplements lower blood pressure or improve exercise performance, and are they safe?
Beetroot juice (also called beet juice) may have a very modest effect on lowering blood pressure, although this affects systolic more than diastolic pressure and it does not seem to help people with hypertension already treated with medication. This effect is likely due to nitrate in beetroot. It is unclear if beetroot supplements provide this benefit due to varying and often low amounts of nitrate.
Nitrate in beetroot can also increase blood flow to muscles, but the evidence is mixed as to whether beetroot juice improves physical performance. At best, it modestly improves some aspects of exercise endurance or performance, especially in people who are not trained athletes and when the exercise is more physically challenging than to what one is accustomed.
