The Cochrane Systematic Review of 15 trials (1,360 people), released this month, states:
“We found that zinc (lozenges or syrup) is beneficial in reducing the duration and severity of the common cold in healthy people, when taken within 24 hours of onset of symptoms. People taking zinc are also less likely to have persistence of their cold symptoms beyond seven days of treatment. Zinc supplementation for at least five months reduces incidence, school absenteeism and prescription of antibiotics for children with the
common cold.”
While they highlight the need for further research into exact dosage and duration for optimal effects of Zinc, any progress made into reducing the impact of colds is very welcome.

You have left out the bit where they expressed concerns ove toxicity which worries me as I take zinc everyday.
They do highlight the need for further research on the optimal dosage for this application of Zinc, Denis- if you are taking a Zinc supplement then the recommended daily amount is 10mg and the safe upper limit is 25mg. If you are concerned that your intake exceeds this, then do check with your doctor for guidance.
