Creatine is a chemical waste molecule produced from muscle metabolism. Simply put, it is the product taken when creatine phosphate, which an important energy molecule in the skeletal muscles, breaks down. This is not a unique product. In fact, it is present in all human beings and is produced according to the individual's muscle mass. It is important in the energy production process in muscles.

According to medical experts, 95-98% of creatine phosphate in our body is stored in our muscles and about 2% of this is converted into creatinine every day. The remaining 2- 5% of creatine can be found in various other parts of the body including the brain, heart and testes. This chemical waste molecule, creatinine, is filtered throughout the system by traveling through the bloodstream to the kidneys. The kidneys, in turn filter these out of the body through a person's urine.

Despite the fact that Creatine is a chemical waste molecule, it still has a very important and essential diagnostic purpose. Creatine has been found to be acceptably reliable in indication possible kidney disturbances. How does this happen? When the levels of Creatine rise this usually means that the kidney's are damaged or impaired in some way. Logically speaking, as these level continue to rise, the worse the state of the kidney can be. Abnormally high levels of Creatine can be real serious indicators that there is possible sever kidney malfunction or that the kidneys can fail, even at times when patients do not experience any outward symptoms of kidney problems. Because of this standards and processed have included checking the blood and urine for the levels of Creatine produced in the system.

Medical studies show that there are standards already acceptable for Creatine levels in a person's body. Normal level of Creatine found in the blood range from 0.6 to 1.2 milligrams per deciliter in adult males and 0.5 to 1.1 milligrams per deciliter in adult females. As the production of this chemical waste molecule is dependent on muscle mass, it follows that more muscular young or even middle-aged adults may find higher levels of creatinine in the blood than what would be the standard for the general population. Similarly, older people may find less Creatine in their system, again depending on the muscle development over the course of their lives. For example, in the case of an elderly person, particularly fastidious about his/her physical development, more Creatine may be found in the blood and urine tests. Infants and children have the lowest level of 0.2 as a standard but these changes, again, depending on the muscle development. Persons who find abnormally high levels of Creatine in their system are advised to undergo treatment through the use of a dialysis machine which removes the chemical waste from the body.

Interestingly enough, creatine is also something created and recommended as a supplement in someone's diet. The idea behind this is that in this fast-paced, health conscious world, people are more likely to take better care of their bodies. One way this is done is through consistent hard work out. And when this happens the person burns up a lot of calories. A body's supply of Creatine is not without limits. Once you have used up the stored creatine in the body's muscles, on normally has to wait before one is able to exercise the muscles again. Taking a creatine supplement would mean increasing the levels of stored creatine and thus having more energy and more enjoyment while working out. Another thing is creatine supplements have been known to benefit athletes. It must be remembered though that these supplement must be taken in recommended doses with a combination of physical activity to produce results that are physically based.

So basically, how creatine works is that it helps in the use of muscles in general. It is the energy behind the movement of this system. An abnormal level of Creatine, which is the waste product from creatine breakdown, is used to check the well-being of a kidney. On the other hand, creatine supplements can be used to build energy when using muscles and muscle mass as a result of this.
