CREATINE OVERVIEW INFORMATION
Creatine is a chemical that is normally found in the body, mostly in muscles. It is made by the body and can also be obtained from certain foods. Fish and meats are good sources of creatine. Creatine can also be made in the laboratory.
Creatine is most commonly used for improving exercise performance and increasing muscle mass in athletes and older adults. There is some science supporting the use of creatine in improving the athletic performance of young, healthy people during brief high-intensity activity such as sprinting. But older adults don’t seem to benefit. Creatine doesn’t seem to improve strength or body composition in people over 60.
Creatine use is widespread among professional and amateur athletes and has been acknowledged by well-known athletes such as Mark McGuire, Sammy Sosa, and John Elway. Following the finding that carbohydrate solution further increases muscle creatine levels more than creatine alone, creatine sports drinks have become popular.
Creatine is allowed by the International Olympic Committee, National Collegiate Athletic Association (NCAA), and professional sports. However, the NCAA no longer allows colleges and universities to supply creatine to their students with school funds. Students are permitted to buy creatine on their own and the NCAA has no plans to ban creatine unless medical evidence indicates that it is harmful. With current testing methods, detection of supplemental creatine use would not be possible.
In addition to improving athletic performance, creatine is used for congestive heart failure (CHF), depression, bipolar disorder, Parkinson’s disease, diseases of the muscles and nerves, an eye disease called gyrate atrophy, and high cholesterol. It is also used to slow the worsening of amyotrophic lateral sclerosis (ALS, Lou Gehrig’s disease), rheumatoid arthritis, McArdle’s disease, and for various muscular dystrophies.
Americans use more than 4 million kilograms of creatine each year.
How does it work?
Creatine is involved in making the energy muscles need to work.
Vegetarians and other people who have lower total creatine levels when they start taking creatine supplements seem to get more benefit than people who start with a higher level of creatine. Skeletal muscle will only hold a certain amount of creatine; adding more won’t raise levels any more. This “saturation point” is usually reached within the first few days of taking a “loading dose.”
