Creatine, in biochemistry, is a naturally occurring nitrogen-containing organic acid in vertebrates, which can assist in providing energy for muscles and nerve cells. Michel Eugène Chevreul first discovered creatine in skeletal muscle in 1832, and then named it "creatine" according to the Greek word "Kreas" (meat).

It can provide energy quickly (all activities of the human body depend on ATP, that is, adenosine triphosphate provides energy, and the storage of ATP in the human body is very small. ATP is consumed quickly during exercise, and creatine can quickly synthesize ATP for energy supply. The storage of adenosine triphosphate in human body is very small, and it needs to be synthesized continuously, but the synthesis speed of the body is very slow, so the body is tired. Therefore, timely creatine supplementation can effectively improve muscle strength, speed and endurance. Improve physical fitness and training level to prevent fatigue. English alias: anhydrous creatine; Creatine preparation; N- amidino ribonucleoside; 5- chloro -2- methyl trifluoromethyl toluene; N- carbamoyl -N- methylglycine.
