A new study has found that taking zinc can make it easier to fight off a cold. Zinc supplements are associated with reducing the severity and duration of common cold symptoms, according to the research.
Zinc is important for the immune system, and deficiency is thought to increase susceptibility to infections and disease. Zinc is also required for healthy reproduction and growth, wound-healing, insulin production and natural resistance to disease.
The new findings are published in The Cochrane Library, which reviews the latest evidence on medicines. Researchers analyzed data from 15 trials involving 1,360 participants.
The lead researcher of the study said:
"This review strengthens the evidence for zinc as a treatment for the common cold,"
"However, at the moment, it is still difficult to make a general recommendation, because we do not know very much about the optimum dose, formulation or length of treatment."
