Zinc for the common cold: Does it help prevent?

How can one Cold Prevent or shorten it if it already exists? Opinions on this vary widely: While some say you can wait for the flu to subside after a week, others take vitamin supplements or other measures. In this context, zinc is one of the less well-known remedies. The trace element may have the potential to prevent or treat the common cold, reports the “Ärztezeitung”. This was the result of a study conducted by Dr. Michael Allan of the University of Alberta in Edmonton, Canada, and Professor Bruce Arroll of the University of Auckland in New Zealand.

Hygiene, face mask and zinc against cold

Scientists reviewed various studies and data on the means used to prevent colds and the effectiveness of preventive measures. It turns out that thorough hygiene such as washing hands and using protective gloves or face masks were the most effective. In addition, zinc can have a protective effect.

More common cold remedies like vitamins C and D and echinacea, on the other hand, are definitely a no-no. The data has been inconclusive for other preventative candidates, including ginseng, garlicand many homeopathic remedies, as well as gargles for colds.

Potential zinc in adults

Studies in which children took related preparations provided indications that zinc could be appropriate for preventing the common cold. This was about zincsulfate tablets at a dose of 10 or 15 milligrams. The researchers hypothesize that these could have a similar effect on adults to prevent the common cold.

However, not only in the prevention, but also in the treatment of acute colds, scientists classify the therapeutic effect of zinc preparations taken orally as potential – in this case, only in adults, not in children. However, nausea can occur as an unpleasant side effect. However, experts advise against using it intranasally, i.e. through the nose, due to serious side effects. As a general rule, you should seek advice from a doctor or pharmacist rather than start self-medication.
