Vitamin c study for care home residents pulled before it began
NCT ID NCT05122481
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to find the right daily dose of vitamin C for older people living in care homes, who often have low levels of this immune-supporting nutrient. The goal was to gather data for a future trial on whether vitamin C could help reduce the risk and severity of respiratory infections like COVID-19. However, the study was withdrawn before enrolling any participants, so no results are available.
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 (ascorbic acid) dietary supplement
- What this could lead to
- If successful, this study would help design a larger trial testing whether optimal vitamin C can reduce the risk and severity of respiratory infections in vulnerable older adults.
- What could go wrong
- This was only a small pilot study and was withdrawn before any participants were enrolled, so no results are available. It is too early to know if vitamin C supplementation will have any meaningful benefit.
