what is creatine made of

Creatine is a naturally occurring molecule that is created by the kidneys and stored within our muscles. It is made up of three amino acids: glycine, arginine, and methionine. Creatine is also found in our diet within foods like meat and fish. The body produces creatine in small amounts and excretes creatine on a daily basis, which is why some people choose to source extra creatine externally. Creatine monohydrate supplements are manufactured outside the body from sarcosine and cyanamide. These two ingredients are heated and pressurized in a large reaction vessel, creating a liquid that is then cooled and set to become crystalline creatine. This is then purified by centrifuge, which spins out any impurities, and the pure liquid is then vacuum dried and milled into a fine powder, making it easier to dissolve in water.
