When I’m feeling like my workout made me extra sweaty I love to use juice as a means for helping my body to recover and replenish electrolytes lost while sweating. Red, orange and yellow juices overall provide a good source of electrolytes (mainly potassium and some sodium). Beets in particular are known as a rich source of electrolytes, as one small beet contains about 300 mg of potassium and about 70 mg of sodium.It’s best to drink electrolyte-rich juices about 1 hour pre-workout as a way to boost electrolytes in the body, but you can also drink them post-workout as a means for replenishing electrolytes lost through sweat.
