|Number of Subjects
In a randomized, double-blind, placebo-controlled trial, 1,668 military personnel were given 6,000 mg/day of vitamin C or placebo (in 3 divided doses after meals) daily for 30 days during cold season.
There was a statistically significant reduction in the number of participants in the vitamin C group catching a cold compared with placebo. This effect was more reliable in never-smokers.
