Creatine causes kidney damage
evidence
The Claim
Many people believe that creatine can lead to kidney damage or disease. This concern stems from the idea that creatine increases the workload on the kidneys, potentially leading to long-term harm.
Origin
This myth likely originated from early case studies and anecdotal reports that suggested a link between creatine supplementation and kidney issues. Media reports often amplified these concerns.
What Science Says
Research, including randomized controlled trials (RCTs) and meta-analyses, has found no evidence that creatine causes kidney damage in healthy individuals. A meta-analysis of long-term creatine supplementation showed no significant changes in kidney function markers. However, individuals with pre-existing kidney conditions should consult healthcare providers before use.
Verdict
Mostly False
