Dietary supplement intake in gym users is associated with a higher prevalence of slight alterations in liver (AST) and kidney (urea) function markers compared to non-users.

If you take dietary supplements regularly, get your liver (AST) and kidney (urea) markers checked periodically. While the changes found in this study were 'slight' and not necessarily damaging, they indicate that your organs are processing a higher load, and monitoring ensures you catch any trends early.
