Summary

This study tests whether vitamin C can reduce pain from recent muscle, bone, or joint injuries in emergency patients. Adults with moderate to severe pain are randomly given vitamin C or a placebo for three days. The goal is to see if this cheap, safe supplement can offer relief and cut down on opioid use.

What this could mean

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

Active substance: Vitamin C (900 mg twice daily for 3 days)
What this could lead to: If it works, this could provide a simple, low-cost, and safe option to manage pain after injuries, reducing the need for opioids.
What could go wrong: This is a small, early-stage trial (204 participants) testing a short-term effect. Vitamin C may not reduce pain significantly, and results may not apply to all patients.
