The Claim

Watermelon juice containing approximately 1.2 grams of L-citrulline produces a similar reduction in delayed-onset muscle soreness as a pure L-citrulline supplement in healthy young adults.

In plain English

In healthy young adults, drinking watermelon juice with about 1.2 grams of L-citrulline reduces delayed-onset muscle soreness to the same extent as taking a pure L-citrulline supplement.

See the scientific wording

Watermelon juice containing approximately 1.2 grams of L-citrulline produces a similar reduction in delayed-onset muscle soreness as a pure L-citrulline supplement in healthy young adults, suggesting that the bioavailability or physiological effect of L-citrulline from whole food is comparable to isolated form at this dose.

Why this might work

After consuming L-citrulline, the body converts it into arginine, which is used to make nitric oxide. Nitric oxide activates cells that repair damaged muscle tissue, speeding up recovery and reducing the feeling of soreness after intense exercise.

  1. Study: Difference Between Watermelon Juice and Pure L-citrulline on Muscle Soreness After Eccentric Exercise: A Comparative Study

    Drinking a glass of watermelon juice with 1.2 grams of natural citrulline reduced muscle soreness just as much as taking a citrulline pill—so the juice works just as well for this purpose.
