Creatine is a naturally occurring compound that can be found in foods such as beef, pork and fish. The body produces it in your liver, pancreas and kidneys. As you would have to eat a large amount of meat or fish to get a substantial amount of creatine from your diet, supplementing it can be advantageous.
