The Claim
In healthy young adults undergoing eccentric exercise, ingestion of 1.2 grams of L-citrulline in watermelon juice or as a pure supplement does not significantly alter post-exercise uric acid levels at 12 or 24 hours, and the reduction in muscle soreness observed in this context is not mediated through inhibition of uric acid production.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In healthy young adults who perform eccentric exercise, taking 1.2 grams of L-citrulline in watermelon juice or as a supplement does not change uric acid levels 12 or 24 hours after exercise, and the decrease in muscle soreness is not caused by reduced uric acid production.
See the scientific wording
In healthy young adults undergoing eccentric exercise, neither 1.2 grams of L-citrulline in watermelon juice nor pure supplement form significantly alters post-exercise uric acid levels at 12 or 24 hours, suggesting that reduction in muscle soreness is not mediated through inhibition of uric acid production.
L-citrulline is absorbed and turned into arginine in the kidneys, which the body uses to make nitric oxide. Nitric oxide activates cells that repair damaged muscle tissue and releases signals that speed up healing, which reduces the feeling of soreness after exercise.
What the research says
1 studyTaking 1.2 grams of citrulline—whether in watermelon juice or a pill—reduced muscle soreness after exercise, but didn’t change uric acid levels in the blood. So, the soreness relief must come from something else, not from lowering uric acid.
