Does creatine calm inflammation?
Impact of creatine supplementation on inflammation: evidence from a systematic review and meta-analysis of randomized double-blind placebo trials

Surprising Findings
Creatine dramatically reduced PGE2 by 60.9% after extreme endurance events, but had zero effect on CRP or IL-6 in any other context.
PGE2 is a major pain mediator—so this suggests creatine might block pain pathways specifically after muscle trauma, not general inflammation. Most assume it works broadly.
Practical Takeaways
If you’re training for a marathon or ultra-endurance event, try 20g/day of creatine for 5 days before the race to potentially reduce post-race inflammation and soreness.

Claims (5)
Taking creatine supplements, even for a month or longer and no matter how much you take or if you also lift weights, doesn’t seem to lower the body’s main inflammation markers like CRP or IL-6.
Taking creatine daily for 3 months doesn’t seem to lower the body’s low-level inflammation markers in older people or those with knee arthritis—even if they also do strength training.
Taking creatine supplements doesn't seem to help trained men recover faster or reduce muscle soreness after working out in low-oxygen conditions, which means creatine might not protect muscles in every kind of workout.
When ultra-endurance athletes like marathoners or triathletes push their bodies to the limit, taking creatine for five days before the race may help reduce their body’s inflammatory response afterward—like turning down the volume on muscle soreness signals.
There isn't strong proof that creatine lowers inflammation markers in the body—most studies are shaky because they didn’t track all the data and had too few people, so we can’t be sure it really works.
