Should you take zinc for a cold? The pros and cons...

Although there’s no cure to the common cold, you could shorten it significantly by taking some zinc... 

According to a new study in the Canadian Medical Association Journal, adults who took zinc supplements within a few days of their first cold symptoms shortened the length of the cold by about two days. Unfortunately, there was not much difference for kids who took the zinc.

Before you stock up, there is a downside to taking zinc. Common unpleasant side effects may include nausea, upset stomach, vomiting and a metallic taste in the mouth. It is also recommended that you avoid using nasal sprays with zinc to treat a cold, which could put your sense of smell at risk.
