The Claim
L-citrulline supplementation at 100 mg/kg/day for 10 days has no significant effect on blood glucose or lactate concentrations at rest or during high-intensity cycling to exhaustion in healthy adults.
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 100 mg of L-citrulline per kilogram of body weight daily for 10 days does not change blood glucose or lactate levels during rest or intense cycling in healthy adults.
See the scientific wording
L-citrulline supplementation at 100 mg/kg/day for 10 days does not significantly affect blood glucose or lactate concentrations at rest or during high-intensity cycling to exhaustion in healthy adults, indicating no measurable impact on substrate metabolism under these conditions.
L-citrulline turns into arginine in the kidneys, which the body uses to make nitric oxide. Nitric oxide opens blood vessels to improve blood flow, but this does not change how the body uses sugar or produces lactic acid during intense exercise.
What the research says
1 studyThis study gave people L-citrulline for 10 days and had them bike hard until exhaustion. It found no change in their blood sugar or lactic acid levels, meaning the supplement didn’t affect how their body used fuel during exercise.
