Uses: nutritional supplements. Arginine-ornithine cycle is an extremely important component of physiological functions. Eat arginine, L-arginine can increase the liver (arginase) activity, help the blood of ammonia into urea and excreted out. Therefore, L-arginine on hyperammonemia, liver dysfunction and so on.
L-arginine is also the main component of sperm proteins, there is the promotion of sperm quality, and enhancing the role of sperm motility of energy.
