Supplemental Usage and Influence of Vitamin C & E on URTI’s

In this study, researchers investigated the efficacy of vitamins C and E in reducing the occurrence of Upper Respiratory Tract Disease. In a population-based cohort study conducted in Sweden via web questionnaire, 1509 men and women, ages 20 to 60, reported a total of 1181 occurrences of URTI. Poisson regression modeling was used to control for age, sex, and other confounding factors. The authors saw no correlation between vitamin E from food and a reduction of URTI’s among either men or women. Women were associated with a higher food intake of vitamin C, as compared with men. Research suggested that vitamin C from food intake would be sufficient to provide a protective effect against URTI’s for women while men might experience reduced risk through supplemental usage of vitamin E and vitamin C.
