Most human studies have taken place in laboratories, not in people actually playing sports. Although not all clinical studies agree, some conducted in both animals and people have shown that creatine supplements improve strength and lean muscle mass during high-intensity, short-duration exercises, such as weight lifting. In these studies, the positive results were seen mainly in young people, about 20 years old.
Creatine does not seem to improve performance in exercises that requires endurance, like running, or in exercise that isn't repeated, although study results are mixed. Although creatine is not banned by the National Collegiate Athletic Association (NCAA) or the International Olympic Committee, using it for athletic performance is controversial. The NCAA prohibits member schools from giving creatine and other muscle building supplements to athletes, although it doesn't ban athletes from using it.
Creatine appears to be generally safe, although when it is taken at high doses there is the potential for serious side effects, such as kidney damage. High doses may also stop the body from making its own creatine. Some creatine supplements may be marketed directly to teens, claiming to help them change their bodies without exercising. One survey conducted with college students found that teen athletes frequently exceed the recommended loading and maintenance doses of creatine. But creatine has not
been tested to see whether it is safe or effective in those under 19.
