Natrol L-Arginine -- 1000 mg - 50 Tablets

•  NO Precursor for Vascular Support. •  Promotes Immune Function. •  Supports Muscle Metabolism. The amino acid L-Arginine has several major functions in the body including as a precursor of NO. This chemical messenger plays a vital role in vasodilatation relaxation of smooth muscle cells within arterial blood vessels. Dietary L-Arginine provides the nitrogen our bodies use to produce NO. Because of L-Arginine’s potential role in vasodilatation it may support healthy blood vessels. Emerging evidence suggests a role of L-Arginine in immune function. It is well known that the body uses more L-Arginine when it is under stress or injured. Further L-Arginine is also used by the body to produce creatine which supports muscle protein synthesis.
