Zinc may help shorten the common cold

Zinc may help shorten the duration of the common cold in adults, according to a new study.

Researchers at the Hospital for Sick Children have analyzed patient trials comparing zinc lozenges to placebos and found that patients using the zinc appeared to benefit.

However, zinc failed to help children recover faster. Researchers say that could possibly be because the children received zinc in a syrup and at a lower dose.

The study appears in the May 7 edition of the Canadian Medical Association Journal.
