L-Ornithine Alpha-Ketoglutarate (OKG) combines Alpha-Ketoglutaric Acid with Ornithine; the resulting compound increases protein availability and also speeds up the rate and effectiveness of the synthesis of amino acids.While the body generally produces enough Alpha-Ketoglutaric Acid that supplementation is not needed, it is considered conditionally essential during intense exercise. This Ornithine-based compound can increase energy, muscle mass and endurance while slowing the process of muscle catabolism and inhibiting the buildup of fat and muscle fatigue.OKG eventually results in the production of Arginine, which can make the pituitary gland release growth hormone to help muscles develop naturally. It also helps to get rid of excess ammonia. This is particularly important, as ammonia can lead to fatigue and soreness of the muscles.
