Arginine Alpha-Ketoglutarate is an advanced form of the amino acid Arginine. It is used by bodybuilders and athletes to accelerate muscle growth and speed recovery.
Arginine Alpha-Ketoglutarate acts to stimulate the production of nitric oxide in the body. Nitric oxide acts as a master cell molecule, directing and ordering a complex array of activities, it regulates blood flow, muscle contraction, nerve signalling and muscle growth, to name just a few. Arginine Alpha-Ketoglutarate is a natural method of creating nitric oxide in the body, and has also been shown to increase production of it in the blood vessels, where it widens their diameter, increasing blood flow without raising blood pressure.
This enables more blood to flow to the muscles and tissues, delivering increased amounts of protein, carbohydrate and the various anabolic hormones (such as growth hormones and testosterone) needed for muscle growth. When nitric oxide is present in the muscles, it enhances the body's muscle-building mechanism, commonly called protein synthesis.
For a supplement to be effective at boosting nitric oxide levels continuously, it needs to have some kind of extended-release delivery system. This can be achieved by combining Arginine with Alpha-Ketoglutarate.
Various trials have shown that after using AKG, bodybuilders had far larger muscles which lasted longer, and felt fuller and tighter. They were also able to work out for longer, so achieving more muscle. Because arginine also boosts the production of growth hormone, which helps in muscle building, this also contributes to increased muscle size and strength.
