The Claim
A single dose of 1.2 grams of L-citrulline, delivered via watermelon juice or supplement, is associated with reduced muscle soreness after eccentric exercise in healthy young adults and does not significantly affect plasma uric acid levels, indicating that the reduction in muscle soreness is independent of xanthine oxidase inhibition or uric acid modulation.
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.
Taking 1.2 grams of L-citrulline in watermelon juice or supplement form reduces muscle soreness after eccentric exercise in healthy young adults without changing plasma uric acid levels.
See the scientific wording
A single dose of 1.2 grams of L-citrulline, delivered via watermelon juice or supplement, is associated with reduced muscle soreness after eccentric exercise in healthy young adults, but does not significantly affect plasma uric acid levels, indicating that the mechanism of soreness reduction is independent of xanthine oxidase inhibition or uric acid modulation.
L-citrulline gets turned into arginine in the kidneys, which the body uses to make nitric oxide. Nitric oxide activates cells that repair damaged muscle tissue, speeding up recovery and reducing pain from exercise-induced muscle damage.
What the research says
1 studyTaking 1.2 grams of L-citrulline, whether from watermelon juice or a pill, helped reduce muscle soreness after tough exercise — but it didn’t change uric acid levels in the blood. That means it works by some other method, not by lowering uric acid.
