How does creatine affect creatinine levels on lab tests?

May 07, 2026 16:09 Updated

Creatine is naturally converted to creatinine in the body, so supplementation can affect creatinine levels on blood tests in some people. If you are having lab work done or have questions about kidney-related markers, it is a good idea to let your healthcare provider know you are taking creatine so they can interpret your results in context.
