Supplements can help:
Support a healthy heart and circulatory system, as well as boost stamina and exercise endurance. Beets contain naturally occurring nitrates, compounds that improve blood flow throughout the body, including the heart and muscles. These nitrates naturally boost nitric oxide, which helps to open up the blood vessels and lower blood pressure. Beet juice can also boost exercise performance, according to recent research. In one study, drinking beet juice for six days enhanced overall physical performance and heart functioning during exercise. In a separate study, researchers found nitrates enabled people to exercise up to 16% longer by reducing oxygen uptake, thereby making exercise less tiring. The betaine in beets is known to help shield against liver disease by lessening fatty acid deposits.
