Watermelon Juice Rich In Specific Amino Acid Relieves Muscle Soreness After Exercise

Researchers in Spain who tested the effects of watermelon juice on people who exercised found that it actually reduced post-exercise muscle soreness. The effect is probably due to an amino acid known as L-citrulline in the juice. Researchers tested natural juice, juice enhanced with L-citrulline and a placebo drink. Both the natural and enhanced versions of the juice relieved muscle soreness, but the L-citrulline in the natural juice seemed to be more bioavailable – i.e., in a form the body can use more easily.
