Creatine is actually a normally occurring chemical produced in the human body. It is created in the liver and kidneys from the amino acids L-arginine, L-methionine, as well as glycine. Skeletal muscle tissue has nearly 95% of all the body's supply. Although it is found in fish and meat, it is a popular supplement for bodybuilders and athletes mainly because when converted into phosphocreatine it is stored in the muscles and used for energy. Bodybuilders especially value it due to the fact that in the course of short bursts of intense exercise, like weight lifting, phosphocreatine turns into ATP, our body's fuel.
First discovered in 1832, it didn't climb to popularity as a supplement until the early 1990's. Then they found it was safe for naturally and legally improving athletic performance and growing lean muscle mass. This nutritional supplement has such wide appeal with bodybuilders and other athletes that annual sales are reportedly between $100 and $200 million.
It is additionally favored amongst professional athletes. According to published reports, 50% of professional football players and at least 25% of professional baseball players utilize it. It's wildly favored with bodybuilders because it encourages muscle growth and increases muscle mass. Pro athletes like John Elway, Sammy Sosa, and Troy Aikman have widely promoted it as an important element of their athletic achievements.
Creatine use has increased with adolescent athletes who are determined to raise their lean muscle mass rapidly and improve their performance. Unfortunately, they are also the population most likely not to use it in the quantities established by scientific findings. Surveys suggest that adolescents exceed both loading and maintenance dose advice to attain their sought after results quickly. This is worrisome because although generally safe, in higher doses there could be major side effects such as kidney damage.
Professional sports, the National Collegiate Athletic Association (NCAA) and the International Olympic Committee all permit its use. Nevertheless, in 2000 the NCAA prohibited colleges and universities from providing it or buying it with school funds. Without scientific evidence that it is harmful, they will not ban it.
Some questions do remain since not all the scientific studies agree about the benefits of using it. Nevertheless, these variations might be because of such issues as carb consumption, muscle fiber type, amount of physical activity, and fitness level. In fact, one study found that raising carb consumption also increased the muscle's ability to absorb phosphocreatine.
Touted by professional athletes and sports enthusiasts from all around the world, this particular nutritional supplement has been a rising star for nearly twenty years. Some might have more questions but for others the verdict is clearly in. Creatine is actually a winner by a knockout.
