It turns out that zinc can reduce the duration and severity of a cold after all. A new meta-review of medical research shows that when taken within 24 hours of the first signs of a cold (sneezing, coughing ... you know the drill) zinc can shorten a cold by a day and reduce the symptoms.
One of the studies cited in the review was a March 2008 report published in The Journal of Infectious Diseases which showed that zinc could reduce a cold from 7 days to just 4 and reduce the coughing from 5 days to just 2. If you're suffering with a cold these a major improvements!
You probably won't hear much about this on the evening news because the medical industry doesn't want you to know about a non-prescription option that works. Your doctor wants you to come in for another $$$ visit instead of simply picking up some zinc from the supermarket!
