Researchers set up a study to determine whether large doses of a nutritional supplement would shorten the length of time it takes to recover from a cold. three thousand volunteers were split into two groups. for two weeks, members of group a took 3,000 mg of the supplement daily. group b received 3,000 mg of a placebo. at the end of the two-week period, the researchers inserted live cold viruses directly into the noses of all the volunteers. the volunteers in both group a and group b continued to take their daily pills. all the volunteers got colds, and there was no significant difference in the length of time the colds lasted.

This study indicates that nutritional supplements do not have an affect on the common cold. The volunteers that were given the supplement did not experience any significant differences in the duration of their cold. They had the cold for the same duration that the volunteers who were given the placebo did.
