Does Vitamin C Help the Common Cold?
By Dr. Sean Hashmi We all know what a nuisance the common cold can be. For over 60 years people have thought that Vitamin C was a great defense. In fact, Vitamin C’s popularity in treating the common cold rose greatly in the 1970’s when the Nobel Prize winner, Linus Pauling stated its effectiveness based on an earlier trial. But the question remains that whether or not there is any evidence to support the efficacy of Vitamin C? To answer this question, I turned to the Cochrane database. Their systematic review of thirty (yes thirty!!!) trials involving 11,350 participants showed that regular ingestion of Vitamin C had no effect on the common cold incidence in the general population. However, in a subgroup of 642 marathon runners, skiers, and soldiers on sub-arctic exercises had a reduction in the incidence of the common cold by almost 50%. Bottom line is that for most people megadoses of Vitamin C is not beneficial for fighting the common cold.
