Quest l-Arginine is a superior amino acid supplement. Arginine is considered a conditionally essential amino acid because, although the body can normally manufacture it, during periods of stress or if a person is malnourished, arginine can be depleted and it must be obtained from food or supplements. Arginine plays a vital role in many processes in the body, including wound healing, immune support, cardiovascular support, hormone production, and enhancement of sexual function.
