A strong immune system can be able to withstand any virus, including the coronavirus. Although, you have no control over the mandatory antigen fit to fly test you have control over what you eat and do to keep yourself safe.  It is crucial for every individual to maintain a healthy immune system. One of the ways of maintaining a healthy immune system is by way of meeting the needs of vitamin D. You may be asking yourself, what is this vitamin D that we are talking about? Worry not, because I am here to explain to you. Vitamin D according to scientists, is a fat-soluble vitamin. It occurs naturally in various types of food and is also available as a direct supplement. 

Sunlight is important

However, this vitamin can also be produced when the ultraviolet rays from the sun hit the skin. Thus it triggers the synthesis of this vitamin in the body. Interestingly some research has shown that having enough levels of vitamin D reduces the risk of covid-19.  Vitamin D is also beneficial in protecting the body from other common respiratory diseases. Some researchers have proved that Vitamin D is essential to maintaining a healthy weight. If you are planning to reduce your weight then one of the best weight loss tips that we can recommend is to keep your vitamin D levels optimum. 

How then does this vitamin fight COVID-19? 

We all might have heard or learnt about the various benefits of vitamin D. This includes the fact that vitamin D helps to maintain healthy and strong bones. It helps the body to absorb calcium, which is one of the main components that help the body in building blocks. For proper functioning of one’s immune system, the first line of defence against diseases, viruses or even infections, vitamin D is very necessary. It plays an important role in making sure that the immune system responds properly. Although, the government doesn’t have any system in place to check your vitamin D levels beforehand. Testing for vitamin D levels in people can help save millions of lives. 

This vitamin also has some anti-inflammatory as well as immunoregulatory properties, which are very helpful when it comes to activating the immune system defences. People with good vitamin D levels face lesser problems when infected with the coronavirus. 

Vitamin D and Immune Cells

This vitamin also helps in enhancing the functioning of immune cells, in return, it helps protect the body from pathogens. The vitamin is very important when it comes to the functioning of the immune system, which is the reason why studies have found out that once the body has low levels of this vitamin, there is then a high chance of infections and contraction of diseases. Vitamin D has a link to reduced lung function, and this can affect the ability of the body to fight against any respiratory infections. Week lungs means more prone to infection. Such people can spread the virus quickly. Therefore, the government has made it mandatory for people to take an antigen fit to fly test before they start their travel. 

Research about Vitamin D

Certain research which was published in PLOS ONE showed that those patients who had been hospitalized due to COVID-19 and yet had high levels of vitamin D were at a lower risk of dying and did not experience any adverse effects of the virus. This is one of the researches which stands as an example that vitamin D helps protect against respiratory disorders. It also explains how important this vitamin is to the immune health of an individual. Researchers have also found out that the risk factors for coronavirus are the same as those of deficiency in vitamin D. Some of these risk factors may include, older age, obesity and even children. 

Unlike the self-test kits that you can purchase from any government-approved list of providers, there is no kit for vitamin D. To check your vitamin D levels you will have to contact a pathologist. If you find yourselves deficient then you can purchase supplements or medicines online or from a pharmacy.

Importance of Vitamin D

In basic terms, vitamin D is essential for the better functioning of the immune system. It plays a very important role in boosting the response of the system. However, there has been no discovery of a cure to treat coronavirus. And therefore, people have to take a mandatory antigen fit to fly test before they board a plane. But still, few kinds of research have determined the effects of vitamin D. Some studies have researched the link between the circulating levels of 25-hydroxyvitamin D, that is, the biomarker for the status of vitamin D, and the severity brought along by the SARS-CoV-2 infection. The results from two research indicated an inverse relationship between the levels of vitamin D and coronavirus infection.

This means that when the level of vitamin D is low, then the risk of covid-19 increases. The study also concluded that airway diseases are associated with irregularity in the metabolism of vitamin D. It increases the possibility that vitamin D deficiency may be due to a complication in the inflammation of the respiratory tract.

Protection against Coronavirus

Reviews have generally found that supplements of vitamin D are most effective at protecting against ARI. It is good only when taken daily or even weekly, and in small doses. But it is less effective if taken in large doses and in large distances. This vitamin has also been found to be helpful when it comes to reducing mortality rates in elderly people. Such people are among the risk factors for coronavirus. There is yet another study that has shown the possibility of reverse causality.


This means that people with low vitamin D levels have a high risk of contracting covid 19. Despite all these facts, investigators recommend more research to be done on this issue of covid 19 and vitamin D.  But as research continues, people need to understand that vitamin D deficiency increases the rate of release of cytokines. This in return causes severe damage in the tissue as well as the severity of an infection.
