I wrote earlier about the role nutrition may play in the prevention of COVID-19. This is a hot topic not only as a matter of public health, but also in the food and supplements space. If vitamin D is proven to reduce the risk and/or treat patients with COVID-19, there is certain to be an uptick in the sale of foods and supplements rich in the ingredient. As this article notes, "'Your shadow has to be shorter than your height to make vitamin D.' Sunbathing on a bright December day in New York City’s Central Park won’t cut it."
Researchers around the globe are investigating whether vitamin D, known as the sunshine vitamin, can help reduce people’s risk of catching the new coronavirus and even aid in treating patients with Covid-19.
