In brief: Vitamin C & colds

This topic has been debated.
The data suggest that it can reduce duration of colds slightly but it does not prevent or reduce the severity of colds for most people. Some studies of people living in extreme circumstances, including soldiers in subarctic exercises, skiers, and marathon runners, have found a significant reduction in the risk of developing a cold with vitamin c by nearly 50%.
