Creatine supplementation and possible side effects
Abstract
The creatine is a popular supplement used by professional athlete, amateurs, recess sports practioners, in an effort to increase in the muscle bigger fosfocreatine stocks to build and give extra energy in the form of adenosina trifosfato, aiming to increase the performance in exercises of high intensity and short duration. This study aim is to weigh the existing literature up under the possible effects of the creatine supplementation in the renal and liver function, gastrointestinal sintoms, cardiovascular effect and thermal exhaustion. A search of pubmed has been led to identify important articles using key words as: creatine, supplementation, risk. According to the existing literature the creatine supplement seems safe, when it is used by healthy adults in the recommended dosage (20g per day divided up in 5g during 5 days) and in the maintenance dosage (5g per day). In the subjects with renal disease history, gastrointestinal sintoms, the creatine can be associated to a greater risk to these diseases and sintoms. Therefore the creatine supplement safeness in children, pregnant and nursing women hasn’t been established. The lackness of side effects doesn’t mean safeness, it’s necessary researches that investigate the creatine supplementation effects in long term. And its prescription has to be done by professionals, determining the recommended dosage, the manufacturer advising about the possible side effects, and if the subject can use the creatine.
