Summary

This study tested whether giving high doses of vitamin C through an IV to severely burned patients could prevent organ failure and death. About 666 adults with deep burns covering at least 20% of their body were to receive either vitamin C or a placebo, alongside standard care. The trial was suspended, so we don't yet know if vitamin C helps.

What this could mean

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

Active substance
high-dose intravenous vitamin C (ascorbic acid)
What this could lead to
If it works, this could offer a simple, low-cost way to reduce organ damage and improve survival in severely burned patients.
What could go wrong
The trial is suspended, so results are unknown. High-dose vitamin C may cause side effects like kidney stones or interfere with other treatments. Early evidence is mixed.
