The results of three meta-analyses show that vitamin C in doses ranging from 200 mg to 2 grams per day reduce duration, but not incidence, of the http://en.wikipedia.org/wiki/Common_cold by 8% for adults and 14% for children. Incidence appears to be reduced by 50% in stressed adults such as soldiers or athletes in extreme, cold environments. The clinical significance of these effects is uncertain, but the biological effect appears genuine.[8][18]
A 2010 http://en.wikipedia.org/wiki/Cochrane_Collaboration concluded:[19]

[INDENT] The failure of vitamin C supplementation to reduce the incidence of colds in the general population indicates that routine prophylaxis is not justified. Vitamin C could be useful for people exposed to brief periods of severe physical exercise. While the prophylaxis trials have consistently shown that vitamin C reduces the duration and alleviates the symptoms of colds, this was not replicated in the few therapeutic trials that have been carried out. Further therapeutic RCTs are warranted.
