| L-Arginine is a conditionally essential, free form, basic amino acid involved primarily in urea metabolism and excretion as well as DNA synthesis. L-arginine is an essential amino acid. It is required for the body to synthesize nitric oxide, which enables the arterial system to retain its youthful elasticity. Nitric oxide also helps to produce endothelial relaxation factor, which is needed by the arterial system to expand and contract with each heartbeat. L-arginine has been shown to promote natural growth hormone (GH) release from the pituitary gland. GH promotes healthy anabolic metabolism throughout the body, helping to maintain protein synthesis within cells. |
