Creatine Category: Stimulants
How it’s used
Creatine is naturally produced in your body from three amino acids (arginine, glycine, methionine) for your muscles to use. Most of your body's creatine is in your skeletal muscle. You can buy it as a diet supplement in powder or tablet form. You can also buy foods with creatine in them. These are used by body builders to provide energy to muscles for movement. It does this by increasing the amount of ATP (adenosine triphosphate) in your body. Creatine can also be used to help people with neuromuscular disorders such as Parkinson’s and Huntington’s disease.
