Bottom line. Creatine may modestly help inflammation in specific populations (Grade C, moderate certainty), especially in adults. Dose range: varies across trials. [1 RCT]

Direction
null
Magnitude
Meta-analysis: creatine supplementation did not significantly reduce inflammatory biomarkers (CRP, IL-6) in humans, either acutely or chronically. Certainty of evidence was rated moderate. The authors note some benefit was observed specifically under conditions of intense physical stress, but the general anti-inflammatory claim is not supported.
