Beet juice even helps you flex your mental muscle: In a Wake Forest University study conducted last year, subjects who consumed 16 ounces of beet juice a day for two days showed an increase in blood flow to the frontal lobe of the brain—the area responsible for processes like planning and problem solving.
One thing that all of the latest research on beet juice has in common is a concluding note that more research should be done to investigate further benefits of the substance. Clearly, scientists believe that there is even more to this versatile ingredient than has already been discovered. Until then, pick up a pre-workout supplement containing beet juice and start reaping the benefits.
