Looking to build muscle and boost their exercise performance, many athletes increase their intake of creatine. Found in meat and fish and sold in supplement form, creatine is essential to the production of energy that muscles need to function properly. It's also produced naturally in the human body, and primarily stored in the skeletal muscle.
There's some evidence that taking creatine can enhance performance in certain high-intensity physical activities (such as sprinting and cycling).
