Can vitamin c shield the brain from too much oxygen?
NCT ID NCT07369232
First seen Feb 01, 2026
Summary
This study looked at how breathing pure oxygen for 30 minutes affects blood flow and stress in the brain, and whether vitamin C can help. Thirteen healthy adults took part, each receiving either vitamin C or a placebo before oxygen. Researchers measured brain blood flow, skin perfusion, and blood markers. The goal is to better understand oxygen's effects on the brain, not to test a treatment.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Oxygen and vitamin C (ascorbic acid)
What this could lead to
If successful, this could help doctors understand how to use oxygen more safely in hospitals, potentially reducing brain-related side effects.
What could go wrong
This is a very small, early study in healthy volunteers, not patients. Results may not apply to sick people, and the effects may be too subtle to measure reliably.
