Beet juice boasts many amazing benefits including boosting stamina, improving blood flow, and increasing energy, making this classic recipe loved by many athletes! The juice from beets contain high levels of nitrates (not the bad kind found in deli meats) that your body converts into nitric oxide. Nitric oxide helps the muscles take in more oxygen, which increases your stamina. It can help you workout longer without feeling tired. Beet juice has many benefits for the non athletes as well. It regulates blood pressure, aids in digestion, is packed with phytonutrients and regulates blood sugar.
