The Claim
Acute supplementation with L-arginine and citrulline malate reduces the time to reach peak power during a 30-second Wingate anaerobic test by approximately 40% in trained men, without increasing peak or mean power output.
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 trained men, taking L-arginine and citrulline malate before a 30-second all-out cycling test reduces the time it takes to reach maximum power by about 40%, but does not increase the highest power or average power achieved.
See the scientific wording
Acute supplementation with L-arginine and citrulline malate reduces the time to reach peak power during a 30-second Wingate anaerobic test by approximately 40% in trained men, though it does not increase peak or mean power output.
The supplement provides raw materials that the body uses to make a chemical that opens blood vessels, allowing more oxygen and fuel to reach muscles faster. This helps the muscle's fastest energy system turn on quicker, so peak power is reached sooner without making the muscle stronger.
What the research says
1 studyTaking this supplement before a short, all-out bike sprint helped trained men reach their maximum speed 40% faster, but didn’t make them pedal harder or longer. So yes, it helps them get up to speed quicker.
