Arginine is one of the 20 amino acid building blocks that are responsible for creating each and every protein in our bodies. Arginine has a plethora of diverse biochemical functions including injury repair, hormone release, and a precursor to many vital compounds. Arginine-AKG is a more bio-available form of Arginine (or L-arginine) which is a crystalline free-form amino acid involved in numerous areas of human biochemistry, including muscle metabolism, ammonia detoxification, hormone secretion and the immune system.
L-arginine is considered a semi-essential amino acid, because although it is normally synthesized in sufficient amounts by the body, supplementation is sometimes required. Arginine and Nitric Oxide (NO) Arginine is a precursor to NO, this means arginine is necessary for NO to form. In fact arginine is involved in the rate-limiting, or slowest, step in NO production. Therefore increased arginine levels will result in higher quantities of NO in the bloodstream, faster. NO is one of the most potent vasodilators the body can produce. Vasodilators widen blood vessels which results in numerous benefits for body builders. Wider blood vessels translate to increased blood flow which means more efficient delivery of nutrients and removal of waste products. Wider blood vessels also lead to decreased blood pressure. Arginine Improves Growth Hormone (GH) levels Arginine stimulates the natural release of growth hormone and is a far safer and more cost effective alternative to GH treatment such as HGH injections.
Growth hormone is one of the most powerful hormones in the body which promotes the growth of lean muscle tissue and fat loss. As you age, GH levels drop, which is one reason you lose muscle and gain fat. In a controlled trial, when arginine and other amino acids were combined with weight training, a greater decrease in body fat was obtained after only five weeks than when the same exercise was combined with a placebo. Arginine is also needed to increase protein synthesis, which in turn increases muscle growth.
