Impact of nutritional protein supplements on liver and kidney functions among athletes attending gym

Abstract

Whey protein is best recognized as a nutritional supplement that has been increasingly popular among gym users as the primary sports nutrition product used by athletes to improve exercise performance, body composition, and muscle growth. The types of supplements utilized can have a big impact on how athletes are treated medically. Two goals guide this work. To begin with, assess athletes' protein consumption. Second, we want to see if whey protein supplements alter the function of athletes' livers and kidneys. This is an analytical cross-sectional study conducted on 105 healthy male gym attendants in Al Nasiriyah city, Thi-Qar, Provence, south of Iraq, from June to November 2021. They were divided into two groups of athletes: group 1 (non-protein group) and group 2 (protein supplements group) with age of Mean ±SD of (27.56 ±8.31 years) and (29.26 ±7.35 years) respectively. The results indicate that athletes consume protein at a higher rate than the RDA for the general population, whether or not they utilize supplements. In terms of liver and renal function biomarkers, the results demonstrate no significant difference between the protein supplement group and the non-protein supplement group.
