Vitamin C supplements can reduce risk of catching a cold,
A daily 500-mg dose of vitamin C is effective in reducing the incidence of colds, according to the results of a study reported in the European Journal of Clinical Nutrition. A group of 244 subjects received a daily supplement of either 50 mg or 500 mg of vitamin C over a five-year period. There was no difference between the two groups in the duration or severity of infection; however, the group taking 500 mg daily caught far fewer colds - a 66% decreased risk of catching three or more colds over the course of the study. The significantly smaller number of infections is especially remarkable because, over the five-year period, the participants were repeatedly exposed to several cycles and seasons of cold viruses.
