Vitamins are essential for the human body as they play key roles in a lot of processes that take place in the body. Vitamin D plays an essential role in the health of bones and teeth, but some studies argue that it could have additional uses.
An in-depth meta-study explored results from 25 different trials in an attempt to observe if the use of Vitamin D could prevent the appeareance of severe respiratory infections. More than 11,000 people participated in the trials. According to the results, vitamin S prevented the appearance of severe respiratory tract infections.
Vitamin D and the body
Some experts have cited the meta-study as evidence that vitamin D could be used against COVID-19. Proper vitamin D levels can help the body to fight against the virus, as it does in the case of other respiratory infections. It also suggested that people with a vitamin D deficiency can be more vulnerable.
This approach can also explain while people from disfavored groups are also more likely to get the infection. People with darker skin tones are also more likely to have a vitamin D deficiency since their body needs more UVB light to generate a proper amount of vitamin D.
Conflicting studies
Recent studies have offered clashing points of view. A pair of studies conducted in the UK argue that there is no link between the use of vitamin D and higher chances of preventing an infection.
Other studies come with a different point of view, arguing that low levels of vitamin D can be tied to an increased chance of developing a severe form, and are more likely to die from the infection in the long run. However, more complex studies are required to determine if vitamin D is useful or not.
A prime requirement is the use of a reasonable data set that can take into account several factors.
