ARGININE
This amino acid is thought to be essential in muscle metabolism because it provides a vehicle for transport, storage, and excretion of nitrogen. Natural sources of arginine are brown rice, nuts, popcorn, raisins, and whole-wheat products.
L-Arginine has become known in the bodybuilding word as a growth hormone (GH) releaser. The amino acid has also been found to have a positive impact on the immune systems and might possibly help in the treatment of some forms of cancer and in recovery from an illness or surgery.
The most recent research indicates that L-arginine is not only essential to normal heart health, but may soon become standard treatment for heart-disease patients and possible impotence. Arginine is the primary source of nitrogen molecules, which convert into nitric oxide, dilates blood vessels causing blood flow to the penis. No nitric oxide, no erections; more nitric oxide, bigger and better erection.
Arginine also lowers blood pressure when given intravenously or orally. Nitric oxide is a second messenger and is important in the control of resting blood pressure. Derangement of the L-arginine nitric oxide pathway may cause certain types of hypertension.
