Pharmacology Creatine is a natural derivate of an amino acid and is synthesized in the liver, kidneys and pancreas out of arginine, methionine and glycine. It also can be taken from foods especially in red meat and fish. The amount of creatine in an average diet is 1-2 grams each day.
Creatine is removed from the body by the kidneys as creatinine.
A well trained creatine system puts less pressure on the lactic shuttle, so less lactic acid arises. Therefore creatine can be seen as a lactic buffer. But only in several types of sports, which mainly depend on this creatine system. Examples on these sports are rugby, soccer and athletics like 100 m dash and javelin. Others sports with explosive power elements can also benefit from creatine like body-building, baseball, volleyball and basketball.
