The Claim
In healthy young adults undergoing eccentric exercise, consumption of 1.2 grams of L-citrulline, whether as a pure supplement or in 750 mL of watermelon juice, is associated with a clinically meaningful reduction in delayed-onset muscle soreness at 12 and 24 hours post-exercise as measured by visual analog scale, with no significant difference between the two forms.
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 either as a supplement or in 750 mL of watermelon juice is linked to a measurable decrease in muscle soreness at 12 and 24 hours after exercise, and both forms produce the same effect.

L-citrulline enters the body and is turned into arginine in the kidneys, which then fuels the production of nitric oxide. This gas signals muscle cells to activate repair cells and release growth factors that fix damaged tissue, leading to less pain after intense exercise.
What the research says
1 studyThe study found that both a L-citrulline pill and a glass of watermelon juice helped reduce muscle soreness after hard exercise, and neither worked better than the other. So yes, both forms help.
