L-Citrulline is an amino acid that plays an important role in nitric oxide metabolism and regulation. In the body, L-Citrulline is converted to L-Arginine to support L-Arginine and nitric oxide levels.
Increased production of nitric oxide promotes vascular dilation, which may help to improve oxygen and blood circulation throughout the body.
It is also thought that L-Citrulline raises plasma L-Arginine, thereby allowing higher protein synthesis and protein content in muscle during exercise.
