The Claim
Long-term L-citrulline supplementation combined with regular exercise in adults is associated with a small but statistically significant reduction in total body fat mass (standardized mean difference: -0.21, 95% CI: -0.40 to -0.01) and android fat mass (standardized mean difference: -0.32, 95% CI: -0.57 to -0.07), without altering overall body weight or lean mass.
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 adults, taking L-citrulline supplements regularly along with exercise is linked to a small decrease in total body fat and fat around the abdomen, without changing overall body weight or muscle mass.

Long-term L-citrulline supplementation combined with regular exercise in adults is associated with a small but statistically significant reduction in total body fat mass (standardized mean difference: -0.21, 95% CI: -0.40 to -0.01) and android fat mass (standardized mean difference: -0.32, 95% CI: -0.57 to -0.07), suggesting a targeted effect on central adiposity without altering overall body weight or lean mass.
L-citrulline boosts nitric oxide production, which opens up blood vessels in belly fat, allowing more fat to be broken down and used for energy during exercise.
What the research says
1 studyTaking L-citrulline pills along with working out helped people lose a little bit of belly fat without losing weight or muscle—meaning they got leaner around the middle without getting lighter overall.
