The use of zinc can help prevent colds

22/11/2013 - Antiviral

Dietary supplements containing zinc may help to get rid of common cold and prevent the disease, say British researchers.

Scientists have analyzed the results of 15 clinical trials conducted since 1984. Studies volunteers were given daily tablets containing from 30 to 160 milligrams of zinc. It was found that people who took zinc had short duration of the disease and reduced severity of symptoms.

Participants taking syrup or tablets with zinc every two hours during the illness have recovered in the first week 2 times frequently, as opposed to those who took a placebo. The children who took zinc containing tablet once a day for at least five months, had one-third less likely to have colds as compared with placebo.

The recommended daily dose is 15 mg. However, experts say that the best dose is not yet defined, while in some cases the use of zinc can cause side effects, including nausea and diarrhea.
