Creatine is classified as a supplement under the Dietary Supplement and Health Education Act of 1994 and available over the counter to anyone. Creatine is not regulated by the Food and Drug Administration and not subject to the same scientific scrutiny as drugs. What is Creatine Creatine monohydrate is a compound produced by the body that helps release energy in muscles. ATP is produced by mitochondria present in all most all cells in the body, including muscle cells.
Creatine also reduces energy waste products.
A normal liver makes about 2 grams of creatine each day. Creatine also is readily available from meat in your diet. Creatine levels are relatively easily maintained, and muscles can store creatine. It has been claimed that protein requirements can be decreased by taking supplemental creatine. The kidneys remove excess levels of the substance, which casts some doubt on whether creatine supplements are of any value to someone who already has a high muscle creatine content.
