Creatin is made by your body and can also be taken as a supplement. As mentioned above it is used by athletes who are trying to bulk up or add muscle. Taking creatin in conjunction with weight training is supposed to cause a quicker and greater gain in muscle.
The main role of creatine in the human body is to bring energy to all the cells of the body. It primarily does this for muscles.
This is why creatine supplements are used so much by people who want to increase their muscle mass. If you have more creatine in your body, it helps to build your muscles faster by increasing the amount of ATP that is available to muscles.
Creatine was discovered in a meat extract in 1832, by the french scientist Michel Eugène Chevreul.
Creatine name comes from the Greek word "kreas"which means flesh. In 1923 it was found that 95% of the total amount of creatine from our body, is found in skeletal muscles.
Creatine and ATP (adenosine triphosphate) form adenosine diphosphate(ADP) and phosphocreatine. ATP is a very important substance in the process of generating the energy necessary for efficient muscle contractions.
