Creatine is a fitness supplement which has been tried and trusted by fitness buffs and scientists for years, and can come in numerous different forms. The most common and popular form of creatine is creatine monohydrate, which help the muscles to work for longer with shorter rest periods. This helps you improve your strength, endurance and performance in the gym, which in turn helps you get stronger and build bigger muscles.
The way creatine works is by helping the body regenerate ATP (Adenosine triphosphate) quicker, which is vital because ATP are the fuel of all muscle movement so the fast it regenerates the more reps you can perform and the more stimulus your muscles receive to build. Other forms of creatine include creatine ethyl ester which some believe is digested and absorbed by the muscles in a different, quicker way.
