A recent study posted on the Journal of the International Society of Sports Nutrition (JISSN) website has determined that long term creatine supplementation does not impair kidney function. This is great news since many competitors use creatine as part of their daily supplement prescription.
The purpose of the study was to determine the effects of creatine supplementation on kidney function in resistance-trained individuals ingesting a high-protein diet. There is a common fallacy that utilizing creatine will impair your kidneys and cause water retention, both of these myths hold no truth. In fact, there have been plenty of studies to prove otherwise. The results of creatine use in one study showed greater gains in total body mass and fat-free mass.
The results of the study posted on JISSN have determined that creatine is safe to use, delivers results and does not harm kidney function. With any supplement, if you have medical concerns, you should seek the advice of a medical professional.
