Citrulline, an amino acid in watermelon, can reduce muscle soreness. Watermelon juice enhances the absorption of citrulline.

One small study gave athletes watermelon juice alone, watermelon juice mixed with citrulline, or a drink that included only citrulline. Both drinks with watermelon resulted in faster muscle pain relief and faster heart rate recovery, compared to drinks containing citrulline alone.

The researchers also conducted an in vitro study investigating the absorption of citrulline. Results showed that citrulline absorption was most effective when it was consumed as an ingredient of watermelon juice.

In addition, scientists are also studying citrulline's potential to improve endurance and exercise performance. However, the results of the initial study did not show an association.
