Protein supplements are one of the most used ergogenic supplements by elite athletes. Nonetheless, it has been postulated that the use of these type of supplements may cause chronic renal failure. The objective of this study is to analyze the effects of the consumption of protein supplements in the renal function of elite athletes of the Mexican Olympic Training Center.


74 athletes provided urine samples in order to quantify urinary proteins. Some of them were excluded since they had conditions that could cause proteinuria or alter the quality of the samples. Those that were not excluded were divided into two groups: the experimental group, which included those individuals that had the antecedent of consuming protein supplements, and the control group, that encompassed those individuals that did not had the antecedent of consuming protein supplements.


Of the 74 analyzed athletes, 44 were excluded, 11 individuals were included in the experimental group, and 19 in the control group. Microproteinuria was encountered in only one urine sample (control group), and it was determined that there was no significant differences between both groups.


From the gathered results it can be concluded that protein supplements do not affect renal function. Nonetheless, in the future protein supplements should be evaluated in groups with pathologies or conditions that may compromise renal function.
