Does creatine work?

According to WebMD, studies show that the effectiveness of creatine varies based on the purpose of use and the specific individual using it. Creatine is most commonly used as a means to improve performance and muscle mass in athletes and older adults.

WebMD states that creatine has been shown to be the most effective in improving the performance of young, healthy individuals participating in short duration, high-intensity activities, such as sprinting. While creatine has been suggested to be useful in various diseases of the muscles and nerves, and numerous other disorders, WebMD indicates that further studies are necessary to confirm these findings.
