As early as January 2020, we told you that if you haven’t done so far, you might want to start taking vitamin D. This recommendation was based primarily on the fact that there is an evincible association between the coronavirus-like H1N1 virus infection and low vitamin D levels.

Since then, more and more scientific research has jumped on the subject, as vitamin D can be produced in infinite amounts, it's cheap to buy, and has many other positive properties in addition to preventing virus infections, for example, reducing depression1. Prescribed drugs cannot do that as they were only invented to treat one disease at a time.

In other words, it would be a pleasant way – and at the same time, a budget-saving solution – in the battle against the coronavirus if everyone had enough vitamin D flowing in their body.

Calculating optimal vitamin D levels

Just how much vitamin D you need can only be found out by doing blood work. But if you want to be sure, take at least 4,000 IU of vitamin D daily as a dietary supplement. This is a safe amount even according to the most careful official recommendations.

If you've got your blood work done, here's a little explanation:

  • Low vitamin D levels: 20-30 ng/ml - 50-75 nmol/L
  • Suitable vitamin D levels: 60 ng/ml to 150 nmol/L
  • Toxic vitamin D levels: above 150 ng/mL

How does vitamin D assist the body in the battle against coronavirus?

The immune system often tries too hard to defend against the coronavirus, which can even lead to a fatal cytokine storm. Vitamin D3, unlike other anti-COVID-19 drugs, contributes to the support of the immune system by not suppressing it, but only regulating it. In other words, vitamin D is cooperating with the immune system. It's like a good team player, as opposed to a bad leader.

The rest of the article sums up the results of the latest scientific research on the topic COVID-19 vs Vitamin D.

1. Most COVID-infected people are vitamin D deficient

The latest research2 showed this in The Journal of Clinical Endocrinology & Metabolism just last week. The previous hypothesis was completely backed by this study: 82% of coronavirus-infected patients admitted to hospital were deficient in vitamin D, meaning there's a strong association between low vitamin D levels and coronavirus infections.

It is known that inadequate vitamin D levels cause more inflammation in the body, which significantly reduces the chances of survival if you get COVID.

We can see it's true by our very own eyes: in summer, during the "natural vitamin D refueling" (sunbathing) period, there were like a handful of infected people compared to nowadays, and immediately after the summer, the situation got rough. This can't be a coincidence, but the result of reduced vitamin D levels in the population.

Although no correlation was found between the course of coronavirus disease and vitamin D levels in this research, we will address this topic in more detail soon...

2. Vitamin D can reduce the amount of bradykinin

It has also recently been discovered that this damn virus can attack the lungs by increasing the production of a substance called bradykinin in the body. This thing produces a gel-like substance in the lungs that makes it very hard to breathe. This is perhaps even more dangerous than the cytokine storm, doctors say.

Our beloved vitamin D inhibits the synthesis of bradykinin, thereby reducing its amount in the body.

3. Low vitamin D levels can increase the chances of developing pneumonia

In a recent study3 E Kenneth Weir and colleagues pointed out that low vitamin D levels:

  • increase the chance of developing pneumonia and viral upper respiratory tract infections
  • increase the number of inflammatory cytokines,
  • decrease the number of beneficial T lymphocytes, and
  • increase the frequency of thrombotic episodes

Either way, coronavirus loves those who don’t take vitamin D and/or don’t sunbathe in the summer.

4. Vitamin D deficiency can increase the chances of coronavirus infections

A study in September with 489 participants4 found that people who had vitamin D deficiency throughout the year were almost twice as likely to be infected by coronavirus as those who had normal vitamin D levels.

5. Insufficient vitamin D level = more severe COVID-19

We left the best study to the end5. This is evidence that if you have enough vitamin D in your body, the course of COVID-19 disease will be less severe if you catch it.

“This study provides direct evidence that vitamin D sufficiency can reduce the complications including the cytokine storm and ultimately death from COVID-19,” said research leader Michael F. Holick.

Although not stemming from this research, the figure below also confirms this finding:

However, the researchers added that further randomized experiments are needed to make the above findings are 100% true.

Attention!

We would like to point this out: all this does NOT mean that vitamin D protects against coronavirus infection. Don’t think you are protected from it if you are taking vitamin D.

As stated earlier, more research is needed, and it is also telling that the recently released 90% effective vaccine does not contain vitamin D either, but something else. So everyone should continue to adhere to the regulations (mask wearing, regular hand washing, avoiding contact with others, exercise, proper nutrition, etc.) and take vitamin D, just to make sure!
