Overall, the evidence to date suggests that regular intakes of vitamin C at doses of at least 200 mg/day do not reduce the incidence of the common cold in the general population, but such intakes might be helpful in people exposed to extreme physical exercise or cold environments and those with marginal vitamin C status, such as the elderly and chronic smokers [81-83]. Vitamin C can limit the formation of carcinogens, such as nitrosamines [2,29], in vivo; modulate immune response [2,4]; and, through its antioxidant function, possibly attenuate oxidative damage that can lead to cancer [1].

A prospective study in 20,649 British adults found that those in the top quartile of baseline plasma vitamin C concentrations had a 42% lower risk of stroke than those in the bottom quartile [60]. A few studies in vitro have suggested that by acting as a pro-oxidant, supplemental oral vitamin C could cause chromosomal and/or DNA damage and possibly contribute to the development of cancer [8,88,89]. If subjects' vitamin C levels were already close to saturation at study entry, supplementation would be expected to have made little or no difference on measured outcomes [22,23,41,42]. The following groups are more likely than others to be at risk of obtaining insufficient amounts of vitamin C. Studies consistently show that smokers have lower plasma and leukocyte vitamin C levels than nonsmokers, due in part to increased oxidative stress [8].
