L-Arginine -
L-Arginine is a semi-essential amino acid synthesized by the body from ornithine. Arginine supports protein synthesis as it is involved in the transport and storage of nitrogen. Arginine is important for proper physical performance because it is used by the body to produce creatine. L-Arginine promotes muscle-building activity in the body by increasing levels of anabolic (growth-promoting) hormones such as insulin and growth hormone. L-Arginine shows promise in the treatment and prevention of cardiovascular disease (including atherosclerosis, hypertension, hyperlipidemic and angina pectoris), in the treatment of some forms of male infertility and some kidney disorders and it is helpful in accelerating wound healing in some circumstances.
