FTwo new studies have recently been published, with the same conclusion: vitamin D supplements, or with fish oil, are not effective in protecting against Covid-19 and other respiratory infections.
Previously published studies have suggested that vitamin D supplements may help protect against these types of diseases, including Covid-19, but researchers in the UK and Norway have found this is not the case.
The studies, published in the scientific journal The BMJfound that these supplements, as well as those containing fish oil, have no significant impact on a person’s likelihood of contracting coronavirus or any other respiratory infection.
In an editorial published with the studies, Peter Bergman, a professor at the Karolinska Institute in Sweden, says vaccines against Covid-19 remain the most effective form of protection. Additionally, the professor says that people with normal vitamin D levels should avoid these supplements.
