Natrol: L-Arginine

The amino acid L-Arginine has several major functions in the body, including as a precursor of nitric oxide (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.*

Studies suggests a role of L-Arginine in immune function.* Further, L-Arginine is also used by the body to produce creatine which supports muscle protein synthesis.*
