Does Creatine help inflammation? (Grade — evidence)
Creatine may modestly help inflammation in specific populations (Grade C, moderate certainty), especially in adults. Dose range: varies across trials.
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.

- The one limitation
- Sample sizes are small in most included trials; effect sizes may shrink with larger studies.

Why this grade
Reasoning trace
Grade — at moderate certainty. The grade reflects the direction and size of the effect across the 1 publishable source above; certainty reflects heterogeneity, sample sizes, and design quality. What would move it upward: additional well-powered RCTs in the target population that replicate the effect at similar doses. What would move it down: a large null trial, discovery of publication bias, or a retraction of a keystone study.
Dose & form
Studied intake: varies across trials.

Frequently asked
How long does Creatine take to work for inflammation?
Trials of Creatine for inflammation typically report effects within 2–4 weeks, though individual response varies. Studies rarely find benefit inside 1 week for chronic outcomes.
What dose was used in studies of Creatine for inflammation?
Studied doses for Creatine in inflammation trials cluster around varies across trials. See the dose block for the specific range and how it varies by form.
Does Creatine work for inflammation if I'm not deficient?
The effect concentrates in adults. If your baseline is normal, expect a smaller effect than the trial averages.
Creatine or the next-best alternative for inflammation?
See the compare block above for the head-to-head with the most-cited alternative. Grade + certainty differences matter more than any single trial.

What this is — and is not
- Evidence description
- 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.
- Substrate's interpretation
- Grade — at moderate certainty — the direction and size the studies converge on, as our reading of the corpus.
- Discuss with a clinician
