Beetroot is an inexpensive and abundant source of nutrition. Dietary nitrates are only found in a few plant foods, including beetroot. Nitric oxide, a molecule formed from nitrates, dilates blood vessels, which improves blood flow and helps pretty much all aspects of body function. Powdered beetroot contains more nitrates than whole beetroot. It can help maintain healthy blood pressure, blood circulation and oxygen circulation. Beetroot powder is thus good for heart, improving stamina and increasing energy.
