Vitamin E May Reduce Common Colds in Seniors Living in Nursing Homes
A study found that daily Vitamin E supplements reduced the frequency of common colds among elderly nursing home residents.
Summary
In plain language
Researchers have discovered that taking a daily Vitamin E supplement might help seniors living in nursing homes experience fewer common colds. In a study involving over 600 residents aged 65 and older, those who received Vitamin E had a lower chance of catching a cold compared to those who did not. While Vitamin E didn't significantly reduce serious respiratory infections, it showed promise in protecting against milder illnesses like the common cold. For seniors, this could mean fewer sniffles and more days feeling well. It's a good idea to talk with your healthcare provider about whether Vitamin E supplements might be beneficial for you.
Details
Use the full description to understand the study design, methods, and the limits of the findings.
This study was a carefully designed experiment conducted over a year in nursing homes. Seniors were given either Vitamin E or a placebo, and researchers tracked respiratory infections.
The study found that Vitamin E seemed to lower the risk of getting common colds, with 46% of those taking it getting colds compared to 57% of those who didn't.
However, Vitamin E didn't significantly impact more serious respiratory infections or reduce antibiotic use.
Seniors should consider that while Vitamin E might help with colds, it's not a cure-all, and effects on serious infections are limited.
Always discuss changes in supplements with your healthcare provider.

Research Quality Score
Scored October 25, 2026 using rubric mq-1.8_2026-07-06.
Assessment
The study scored highly due to its rigorous randomized controlled trial design, comprehensive bias control measures, and complete transparency in reporting. However, the lack of external replication and unspecified journal quality limited the overall score. The study's relevance to the target population of seniors was strong, but the involvement of the NIA in data analysis slightly impacted the conflicts score.

Additional Notes
This randomized controlled trial investigated the effect of vitamin E supplementation on respiratory infections in elderly nursing home residents. It found no significant effect on lower respiratory infections but suggested a protective effect against upper respiratory infections, particularly the common cold.
