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 growth hormone treatment such as HGH injections. Growth hormone is one of the most powerful hormones in the human body which promotes the growth of lean muscle tissue and the loss of fat. As you age, growth hormone 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 can in turn increase muscle growth. [1,2].
Growth Hormone (GH) for the athlete:
Athletes involved in intense exercise on a regular basis need Growth Hormone (GH) to increase energy, enhance lean body mass and to maintain strong bones and keep their weight under control. Availability of GH in systemic circulation also helps increase strength, burn fat, enhance libido, boost immunity and support tendons and ligaments. By inducing the secretion of GH from the pituitary, arginine and lysine stimulate muscle metabolism and, hence, provide nutritional support for the athlete.
