Evidence-backed FAQ
Is creatine safe for the kidneys?
Direct answer
Pooled human studies in generally healthy adults have not demonstrated kidney damage from creatine at the amounts and durations studied. These findings do not establish safety for people with pre-existing kidney disease.[1], [2]
What the evidence shows
Creatine can modestly raise serum creatinine because creatinine is a natural breakdown product of creatine; a higher value therefore does not automatically mean kidney injury.[1]
Important limitations
The evidence largely covers healthy adults. People with kidney disease, reduced kidney function, or unexpected laboratory changes require individualized clinical interpretation.[1], [2]
