Zinc Lozenges Capable of Reducing the Duration of Symptoms: Study

coldFinnish researchers have suggested that zinc lozenges can be beneficial in common cold and can reduce its duration by over 40%.

The researchers examined 13 different trials regarding the effect of zinc lozenges on the cold. Three of the studies notified that a daily dose of zinc acetate over 75 milligrams, three times a day, can cut the duration of cold by around 42%. Five others studies reported that taking zinc salt at doses greater than 75mg can reduce the duration by 20%. However, remaining five studies reported that doses lower than 75mg showed no benefit at all.

A report by the researchers was published in the Open Respiratory Medicine Journal, which notified, “Since a large proportion of trial participants have remained without adverse effects, zinc lozenges might be useful for them as a treatment option for the common cold”. Therefore, these studies indicate that zinc may shorten the duration of symptoms.

Bad taste in the mouth, stomach upsets and nausea are few of the side effects that zinc supplement can cause. However, researchers have notified that so far no long term effects from the intake of zinc salt have been reported.
