What purpose does Creatine serve exactly?

Now that you know what creatine is and how your body manufactures it, let’s study the purpose it serves…especially to athletes. Creatine’s main benefit is its ability to aid in the production of energy. When ATP (adenosine triphosphate) loses one of its phosphate molecules and becomes ADP (adenosine diphosphate), it must be converted back to ATP in order for the molecule to be able to produce energy again. The creatine in our body is mostly stored as creatine phosphate (known as phosphocreatine), and it will donate its phosphate to the ADP which renews the ATP molecule and it can now produce energy.
