Zinc 'can cut length of common cold'
Scientists have found that taking zinc tablets “may shorten the duration of a cold”, The Independent reported today.
For many years, laboratory research has suggested that zinc can stop cold viruses from multiplying, but it has not been clear whether this means taking zinc can prevent or ease a cold. To examine the issue, scientists pulled together all relevant studies of zinc as a cold treatment and conducted a thorough range of analyses of their overall findings. They found that zinc lozenges may shorten the length of a cold by one or two days more than taking a dummy placebo treatment, but that taking zinc was also associated with side effects.
