100% Ultra Pure, Ultra Fine 200 mesh Creatine Monohydrate: Creatine is a natural compound made in the body and is derived from the diet through meat products. In the body, Creatine is changed into a molecule called phosphoCreatine which serves as a storage reservoir for regenerating ATP. ATP is the chemical source of energy for muscle contraction and quick energy. PhosphoCreatine is an important source of ATP energy in muscle tissue and studies suggest that Creatine may increase the performance of athletes in activities that require quick bursts of energy, such as sprinting and weight lifting. Creatine supplementation combined with strength training has been suggested to cause improvements in muscle hypertrophy (size) and strength through cell volumization and increased protein syntheses. Creatine is by far, one of the best discoveries that has ever hit the bodybuilding/fitness world. Creatine is a compound which is made in the body from the amino acids glycine and arginine, and is derived from the diet through meat and animal products. In the body, Creatine is changed into a molecule called phosphoCreatine which serves as a storage reservoir for regenerating ATP. ATP is the chemical source of energy for muscle contraction and quick energy. Creatine supplementation combined with strength training has been shown to cause dramatic improvements in muscle hypertrophy (size) and strength through cell volumization and increased protein synthesis. Cell volumization is an increase in muscle volume (size) caused when water follows Creatine into our muscles. Cell volumization can increase strength by increasing the amount of force a muscle can contract with. There is also research that indicates that cell volumization and Creatine supplementation can signal muscle cells to grow and increase protein synthesis, while preventing protein breakdown.
