Creatine

Creatine is an amino acid that occurs in our bodies and is concentrated in skeletal muscles. Recently it has become popular to supplement one’s diet with synthetically produced creatine in hopes of enhancing athletic performance. Creatine monohydrate is most commonly used form in athletics.

For people with congestive heart failure, intravenous creatine has been found to improve heart function, but oral supplementation has not been effective, though skeletal muscle function does improve. Another study, in both men and women, found the creatine signficantly lowered serum total cholesterol and trigycerides, but did not change LDL or HDL cholesterol.

People that do not respond to creatine could become full-fledged responders if they take creatine with high glycemic sugars, which sufficiently works in many instances. But people are warned against doing this because the chronic consumption of highly glycemic sugars can eventually lead to a condition of insulin-resistance. Insulin-resistance is currently one America’s greatest health problems. Not all muscle types respond equally to creatine supplementation either. Muscles can be described as fast or slow. Fast muscle fibers mediate abrupt movements; they also are those that predominantly use creatine energy production. Slow muscle fibers do not rely that heavily on creatine energy production.
