Evidence supporting the use of: Citrulline nitrate
For the body system: Muscles
Synopsis
Source of validity: Scientific
Rating (out of 5): 3
Citrulline nitrate is used to support the muscular system, primarily due to its potential effects on blood flow and exercise performance. Citrulline is an amino acid involved in the urea cycle and is converted in the body to arginine, which is then used to produce nitric oxide (NO). Nitric oxide is a vasodilator, meaning it relaxes blood vessels, which can enhance blood flow to muscles during exercise. Nitrate, on the other hand, is also converted in the body to nitric oxide via a separate pathway. The combination of citrulline and nitrate theoretically provides a synergistic boost to nitric oxide production.
Several studies on citrulline malate (another citrulline compound) have shown improvements in exercise performance, muscular endurance, and recovery, though results are mixed and often depend on dosage and exercise protocols. Fewer studies exist specifically on citrulline nitrate; however, a handful of recent clinical trials have found that it can increase plasma nitric oxide levels and may improve some aspects of exercise performance such as repetitions to failure and perceived exertion. The evidence is still emerging, and more large, well-controlled studies are needed to confirm its efficacy and optimal dosing.
Overall, the use of citrulline nitrate for muscle support is supported by plausible mechanisms and early scientific data, but the evidence is not yet robust or conclusive, justifying a moderate evidence rating.
