In the past 40 years, numerous placebo-controlled trials have examined the effect of vitamin C supplementation on the prevention and treatment of colds. Meta-analysis of placebo-controlled trials evaluated the effect of vitamin C supplementation on the incidence, duration, or severity of the common cold when taken as a continuous daily supplement, or as therapy upon onset of cold symptoms.
Participants undergoing heavy physical stress, (e.g. marathon runners, skiers, or soldiers in subarctic conditions), subject to vitamin C supplementation, halved the incidence of colds. A benefit of regular vitamin C supplementation was also seen in the duration of colds, with a greater benefit in children than in adults. The pooled effect of vitamin C supplementation was a 14% reduction in cold duration in children, and an 8% reduction in adults.Caring partners who want to ensure their family enjoys optimum cold immunity can contact us for more information.
