The amino acids arginine and citrulline play an integral role in the body?s metabolism and utilization of protein and are essential for the maintenance of muscle tissue.* Arginine is a precursor to nitric oxide (NO) which promotes increased circulation by relaxing blood vessels.* Citrulline is necessary for the elimination of ammonia a toxic byproduct of exertion thereby supporting the body?s natural recovery processes after exercise.* In addition excess citrulline is converted to arginine helping to sustain arginine and NO levels better than arginine alone.*Dietary SupplementAmino AcidsProtein Metabolism
