Intake of both is often inadequate, even in affluent populations. The common cold continues to place a great burden on society in terms of suffering and economic loss.
In both studies, a nonsignificant reduction of rhinorrhoea duration (range 9-27%) was seen. In pooled analyses of both studies (n=94), vitamin C plus zinc was significantly more efficient than placebo at reducing rhinorrhoea over 5 days of treatment.
Protection Against Colds
Vitamin C may reduce the length and severity of a cold, but it doesn’t appear to prevent colds in most people, according to the National Center of Complementary and Alternative Medicine, part of the National Institutes of Health.
The exception is marathon runners and other extreme exercisers, as well as people exposed to very cold weather, such as skiers. For these groups, taking 250 milligrams of vitamin C daily may reduce the chance of catching a cold by 50 percent, reports the NIH’s Office of Dietary Supplements. Studies show that using zinc lozenges within 24 hours of catching a cold can reduce the length and severity of cold symptoms.
Eye Disease Protection
Zinc and vitamin C may prevent vision loss in older people by delaying the progression of age-related macular degeneration, or AMD. Additionally, studies show high intakes of vitamin C may protect against cataracts, although the ODS notes this association needs further study. Wound Healing
Vitamin C is needed for the body to form collagen, part of the skin’s connective tissue that plays a vital role in the healing of wounds, such as cuts.
Zinc is needed for the formation and maintenance of the skin and mucous membranes.
