Studies Find that Vitamin D Helps Protect You From Covid-19

Researchers at Trinity College Dublin and the University of Edinburgh took a closer look at Vitamin D exposure and Covid-19. The findings? They found that exposure to ultraviolet B, a UV ray involved in Vitamin D production in the skin, roughly in the weeks before contracting the disease, could significantly improve the chance of recovery.

While previous studies have found that deficiency in Vitamin D increases susceptibility in viral and bacterial infections, this study builds on this evidence and proves that Vitamin D can protect the human body from such illnesses.

During the experimentation process, the research team found that much of their data could be irrelevant because other factors such as obesity, age, and other underlying conditions could cause the person to be more susceptible, leaving Vitamin D out of the question. However, to overcome this challenge, researchers calculated what they call a “genetically predicted” Vitamin D level, which comes from over a hundred genes that provide information about a person’s Vitamin D status. This process is able to bypass the roadblock of taking other factors into consideration.

An article by Trinity College Dublin describes the methods of their research. They state that “The Mendelian Randomisation is a particular analytical approach that enabled researchers to investigate whether vitamin D and COVID-19 might be causally linked using genetic data. Few earlier studies attempted this but failed to show a causal link. This could be because UVB radiation sunshine, which is the most important source of vitamin D for majority of people, was ignored.”

In this experiment, scientists looked jointly at genetically predicted and UVB predicted Vitamin D levels. This provided significantly more accurate data about the specifics of the correlation. The discoveries find an incredibly strong association between Vitamin D exposure and dehospitalization.

“Our study adds further evidence that vitamin D might protect against severe COVID-19 infection. Conducting a properly designed COVID-19 randomized controlled trial of vitamin D supplementation is critical. Until then, given that vitamin D supplements are safe and cheap, it is definitely advisable to take supplements and protect against vitamin D deficiency, particularly with winter on the horizon.”

This new insight given to us is important to both the current pandemic along with any future cases, and should drive us to take bigger and healthier steps to ensure our own safety.
