Creatine is a natural substance found in the human body. It is essential to life, and the average adult has 80 - 130 grams of creatine in his or her body.
Creatine plays a vital role in transporting energy within each of the body’s trillions of cells – in skeletal muscles, the heart, brain and other organs. As well as acting as an energy carrier, creatine almost certainly has other benefits that scientists do not yet fully understand. Many researchers believe creatine is important for the function of organs including the brain, and for general health. It also improves performance and aids recovery in both training and competition.
Taking creatine, even in the short term, may significantly increase your strength, endurance, concentration and recovery. Creatine may also help support your immune system.
