The Benefits and Side Effects of Creatine

What is creatine?
Creatine is an amino acid (amino acids are the building blocks of protein) which is made in the body by the liver and kidneys, and is derived from the diet through meat and animal products. Creatine (creatine monohydrate) is a colorless, crystalline substance used in muscle tissue for the production of phosphocreatine, an important factor in the formation of adenosine triphosphate (ATP), the source of energy for muscle contraction and many other functions in the body.

What does creatine normally do in the body?
In the body, creatine is changed into a molecule called "phosphocreatine" which serves as a storage reservoir for quick energy. Phosphocreatine is especially important in tissues such as the voluntary muscles and the nervous system which periodically require large amounts of energy.

Why do athletes take creatine?
Studies have shown that creatine can increase the performance of athletes in activities that require quick bursts of energy, such as sprinting, and can help athletes to recover faster after expending bursts of energy. Creatine is best for the serious bodybuilder. It helps increase muscle mass, rather than muscle endurance, so it
