From the Lecture series The Skeptic's Guide to Health, Medicine, and the Media Many familiar and unfamiliar minerals, vitamins, and medicines have been studied to find a definite cure for the common cold. Although zinc and vitamin D are not at the top of the list when people think about curing colds, they may be beneficial. Have scientists finally found a cure for the common cold? Read on to find out.

Among all the cures for the common cold, zinc seems to be more effective. There are reliable studies supporting the fact that zinc can reduce the duration of a cold. A study needs to meet certain criteria to be reliable. Did the zinc studies meet those criteria?

This is a transcript from the video series The Skeptic’s Guide to Health, Medicine, and the Media. Watch it now, Wondrium.

Zinc for the Common Cold

A nonprofit organization called the Cochrane Collaboration reviewed 15 studies on zinc. They reviewed studies objectively to find more comprehensive answers to questions and found that taking zinc syrup every two hours reduces the duration of cold up to 50%. The review also pointed out that the intake of zinc might have side effects, including nausea, bad taste, and diarrhea. Further, an article in the Time magazine cited three studies and claimed that “Zinc Lozenges May Help Colds Go Away 3 Times Faster.” It is stated that one should take doses higher than recommended to see effects and be careful with the type of zinc. The claim for tripling the rate of recovery is explained as to how 70% of the 200 people in three studies showed improvement after taking zinc. The results were salient as they were seen regardless of gender, race, age, or smoking status. Further, no participant had reported any side effects. The article also gave some practical advice to look for a specific kind of zinc in the form of zinc acetate lozenges made without added citric acid. Zinc might not be a cure for the common cold, but it can definitely help banish the symptoms quicker.

Vitamin D for the Common Cold

Vitamin C has proven ineffective for the common cold, but some studies show that vitamin D can prevent colds and flu. In 2017, NPR published an article supporting vitamin D in this regard. Another analysis stated that respiratory infections could be reduced by higher vitamin D. Thus, people need to get more sunlight. Results from 25 studies on over 10,000 participants were reviewed to see the effect of vitamin D supplements on reducing the number of infections. The report was strong enough as it included many studies and was published in the reliable British Medical Journal. The participants were both adults and children, and both advantages and disadvantages were covered.

The problem was that they claimed, “Vitamin D supplements seemed to reduce the risk of infection about 10 percent.” The percentage is really not that significant, and the method of calculating it is not specified. However, it is safe to take vitamin D in reasonable doses, even if it does not cure the common cold or prevent it.

A Cure for the Common Cold

In 2017, the UK’s Metro published an article entitled “We May Finally Have Found a Cure for the Common Cold.” It was a very big claim as scientists had been struggling with finding a cure for the common cold for ages. But it was not right. The headline is vague on its own: “May Finally Have Found” does not sound so promising. The second sentence of the article just states how researchers at Edinburgh Napier University have discovered possible new treatments based on antimicrobial peptides that occur naturally in humans and animals and increase the body’s natural response to infection. The research was in the early stages, and no result or remedy was concluded. It focused on peptides, which are chains of amino acids, that had “properties that can combat rhinovirus: the main virus responsible for the common cold in humans.” There were no drugs, no cures, and even no definite results. It was just journalism trying to make the article more attractive. In health news, the article is usually much more important than the headline, as the real story lies in the body of the article, not the headline. The common cold has always been a controversial issue, and no definite cure has been found for it yet. Thus, whatever you read about it should be supported by strong studies, make sense, be salient, and cover both advantages and disadvantages of the suggested cure.
