L-Arginine

Arginine is considered a semi-essential amino acid because, although the body manufactures its own supply, there are times when dietary supplementation may be required, such as in the case of severe wounds or illness. L-Arginine may promote muscle-building activity in the body by increasing levels of anabolic (growth-promoting) hormones such as insulin and growth hormone. L-arginine also works in another way to stimulate erectile function. Boosting arginine levels may help boost the activity of sperm as well.
