L-arginine is a coded amino acid in the synthesis of protein, belonging to one of the eight essential amino acids in the human body. It is needed it to exercise a variety of functions in the body. For example, it stimulates the release of specific chemicals, such as insulin and human growth hormones. The amino acid also helps to remove ammonia from the body and promote wound healing. The body producing sarcosine also needs it. In the decomposition of L-arginine will produce nitric oxide, and it could expand vascular disease and increase blood flow. Under normal circumstances, the body itself can produce enough L-arginine. But in the absence, you can eat arginine-rich foods to add arginine.
