The benefits of drinking beet juice include lowering blood pressure, having more stamina and lowering the chance of inflammation, according to About.com. Beet juice has a strong flavor, so experts suggest mixing it with other juices to mask the flavor.
As of 2015, studies show that drinking only 2 cups of beet juice each day may help lower or keep a person's blood pressure at a healthy level, explains About.com. In a 2008 study, volunteers who drank 500 milliliters of beet juice had a decrease in blood pressure within three hours of drinking it. This drop in blood pressure was still seen up to 24 hours after drinking the juice.
A 2009 study shows that drinking beet juice may help to boost exercise stamina, states About.com. In this study, men drank 500 milliliters of beet juice every day for six days before going through a series of fitness tests. After drinking the beet juice, the men could exercise for an average of about 92 seconds longer than they could before drinking the juice.
Beet juice may also help obese people by lowering inflammation in the body, claims About.com. Inflammation is a risk factor for conditions including cancer, cardiovascular disease and Type 2 diabetes. The study also shows that drinking beet juice can fight free radicals, which are chemical byproducts that may damage DNA.
