This should point to the source Cochrane study at https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD000980.pub4/full https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD... or https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8078152/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8078152/, rather than an interpretation of that study. The authors of the study conclude; > The failure of vitamin C supplementation to reduce the incidence of colds in the general population indicates that routine vitamin C supplementation is not justified, yet vitamin C may be useful for people exposed to brief periods of severe physical exercise. Regular supplementation trials have shown that vitamin C reduces the duration of colds, but this was not replicated in the few therapeutic trials that have been carried out. Nevertheless, given the consistent effect of vitamin C on the duration and severity of colds in the regular supplementation studies, and the low cost and safety, it may be worthwhile for common cold patients to test on an individual basis whether therapeutic vitamin C is beneficial for them. Further therapeutic RCTs are warranted.
