Creatine helpful??: Re Athletic performance: Many factors seem to influence the effectiveness of creatine, including the fitness level and age of the person using it, the type of sport, and the dose. Creatine does not seem to improve performance in aerobic exercises, or benefit older people. Also, creatine does not seem to increase endurance or improve performance in highly trained athletes. I don't recommend it.
