What are the health benefits of beetroot juice?

Beetroot juice can decrease blood pressure and provide energy and endurance for workouts, according to WebMD. A cup has about 100 calories, primarily from carbohydrates, along with vitamins such as potassium, vitamin C, folate and nitrates.

To affect blood pressure, adults should drink 2 cups of beetroot juice per day. Similarly, to help with endurance, adults should consistently drink beetroot juice, as it can take as long as six days to see results, notes WebMD.

Researchers disagree about whether beetroot juice improves circulation. Though some claim it does, researchers at Penn State performed a study that concluded beetroot juice does not substantially increase blood flow to muscles during workouts.
