Many people know Creatine strictly as the supplement that can be purchased from any supplement store.
Alternatively, creatine is an amino acid located mostly in your body's muscles, as well as in the brain. Though it can be made synthetically, most people get creatine through seafood and red meat. The body's liver, pancreas and kidneys also make creatine.
Your body converts creatine to phosphocreatine and stores it in your muscles, where it's used for energy. Although it may seem that it is not necessary to supplement creatine, it is actually very difficult to saturate your muscles with creatine solely from your diet. As a result, people take creatine orally to improve athletic performance and increase muscle mass.
What are the benefits of supplementing with creatine?
Creatine can provide you with short bursts of speed or muscle. This is especially useful for weightlifters or sprinters.
Is creatine safe?
When used orally at appropriate doses, creatine is likely safe to take for up to five years. However, there is concern that creatine taken in high doses is possibly unsafe and could damage the liver, kidneys or heart.
