Creatine as a dietary supplement
By using creatine as a dietary supplement (e.g., in the form of creatine monohydrate), the amount of creatine and creatine phosphate in the muscles is increased. This improves the energy supply during periods of intensive stress on the body as well as recovery times once the exertion is over. For example, creatine increases performance during high-speed workouts when quick, intensive physical activity is required. The use of creatine can help athletes train more intensively, resulting in improved muscle growth and increased strength.
