Summary

This trial tests whether daily creatine supplements can reduce pain, fatigue, and muscle weakness in people with fibromyalgia. Eighty adults diagnosed with fibromyalgia will receive either creatine or a placebo for a set period. Researchers will measure changes in pain levels, muscle strength, sleep quality, and overall well-being to see if creatine offers any benefit.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
creatine dietary supplement
What this could lead to
If it works, creatine could become a simple, low-cost option to help manage fibromyalgia symptoms like pain, fatigue, and muscle weakness.
What could go wrong
This is a small, early-stage trial. Creatine may not outperform placebo, and results may not apply to all fibromyalgia patients. Side effects are possible.
