Main Applications

L-Citrulline is a non-protein amino acid that functions as a precursor to arginine and, in comparison with direct arginine supplementation, has been shown to elevate circulating nitric oxide levels more effectively; it also exhibits natural antioxidant properties. These characteristics underpin its use in sports nutrition products intended to improve blood flow and alleviate muscle soreness, and it is further employed across pharmaceutical, health-food, food-and-beverage and cosmetic applications.
