Creatine supplementation and the young kidney

Key takeaways

This review of existing studies found that creatine supplements do not seem to harm healthy kidneys, but people under age 30 with low kidney filtering rate (eGFR), past kidney disease, or other risks should avoid high doses and extra protein. The review is based on observations in people, so it shows a link between creatine and kidney safety—not proof that creatine causes harm or benefit.
