Zinc For The Common Cold? Full Text
Move over cough syrup and cough drops, there’s another remedy that could cut down cold symptoms for adults. Canadian researchers say oral zinc treatments could not only lessen common cold symptoms, but shorten the duration. Canadian researchers looked at 17 randomized controlled trials with more than 2,000 participants who were between 1 and 65 years old. The double–blinded trials included placebos as well as oral zinc. The authors found that, compared with placebos, zinc significantly reduced the duration of cold symptoms. Researchers also found that high doses of ionic zinc were more effective than lower doses for shortening the duration of symptoms.
