Creatine monohydrate is a product, which is used by professional sportsmen. It supplies more energy during workouts as well as enhances force and strength. Moreover, while it increases fat-free muscle mass, it accelerates losing fat. It helps tired muscle cells refresh their energy during heavy workouts. Thus, heavy workouts may be maintained for a longer time. It provides better and more strength muscle structure. Creatine is synthesized mainly in the kidneys, the liver and pancreas by the use of the amino acids of L-arginine, glycine and L-methionine. After the bio-synthesis, it is transported to skeletal muscles, to the hearth, to the brain and other tissues. Creatine metabolized into creatine phosphate, which is the largest energy storage form in these tissues. Furthermore, this product should also be consumed by vegetarians. Because they do not eat meat, creatine level in their blood is low. It will be useful that they supplement their diet by creatine.
