People primarily use creatine to stimulate increased muscle mass and improve performance in exercise and sports, according to WebMD; however, creatine does not work for everyone. According to Brittany Risher of Men's Health, creatine is best suited for activities that require short, sustained bursts of energy, such as baseball and football. Creatine is also used to treat rheumatoid arthritis, depression, congestive heart failure and high levels of cholesterol, notes WebMD. Creatine is used in the treatment of individuals who cannot manufacture creatine naturally, a condition that can cause autism, seizures and psychological retardation. Creatine treats arginine-glycine amidinotrasferase, a creatine deficiency disorder.

The chemical does not improve endurance in sports or other athletic activities, according to Risher. In addition, creatine does not improve the performance of individuals over 60 years old, highly trained athletes and anyone who consumes meat or fish, both good sources of creatine. The chemical can also cause dehydration because it stimulates muscles to draw large quantities of water from the rest of the body. For this reason, WebMD cautions users to avoid exercising in the heat and to drink a lot of water. Pregnant and lactating mothers and those with kidney problems should avoid using creatine.
