Creatine

Creatine is an organic acid naturally occurring in the body that supplies energy to muscle cells for short bursts of energy (such as lifting weights, short sprints, etc.) via creatine phosphate replenishment of ATP. A number of scientific studies have proven that creatine can increase strength, energy, and muscle mass in addition to reducing recovery time. Also, recent studies have shown that creatine improves brain function, improves recognition memory, and reduces mental fatigue.

With regards to affect on muscles, creatine increases what is known as cell volumisation by drawing water into muscle cells, making them larger. This intracellular retention should not be confused with the common myth that creatine causes bloating (or intercellular water retention). Creatine is sold in a variety of forms, including Creatine monohydrate, Creatine ethyl ester and Creatine malate, among others. Though all types of creatine are sold for the same purposes, there are subtle differences between them, such as price, and necessary dosage.
