A meta analysis looks at all the studies on a given subject and attempts to draw conclusions from them by combining all the data and looking for trends. It is the gold standard for aggregating data and drawing conclusions about study hypotheses. The link to that study is available below. Question #1: Does vitamin C prevent the common cold? In short, no. The study showed that regular supplementation with vitamin C did not significantly reduce the incidence of colds. However, there was a 50 percent decrease in the incidence of colds in a subset of patients exposed to vigorous activity, especially in extreme conditions (marathon runners, skiers, and soldiers in sub-arctic exercises). The reasons for the apparent benefit in this subset of patients are uncertain. Question #2: Does vitamin C treat the common cold? Vitamin C is often touted as a natural remedy for the common cold. The study showed a small but statistically significant 8 percent reduction in the duration of cold symptoms in adults regularly taking vitamin C supplements (at least 200 mg/day). The clinical relevance of this 8% is not known. The meta-analysis also showed that vitamin C given therapeutically after symptom onset did not reduce symptom duration or severity.
