What is Arginine?
Arginine is a non-essential, but very important, amino acid. The body is normally able to synthesize the amino acid if necessary due to an insufficient diet. However, a diet rich in meat, poultry, fish, dairy products, and/or nuts should provide enough arginine for normal function.

Arginine helps keep the heart healthy, helps heal wounds, and aids in the production of insulin and glucagon. If necessary, the body can break down arginine for use as bodily energy or convert it into glycogen. In high doses, arginine may stimulate the secretion of growth hormone and prolactin. The body uses arginine, in addition to glycine and methionine, to produce creatine.
