What is the value of vitamin D in the prevention and treatment of COVID-19?

Vitamin D is not only vital for healthy bones, teeth and muscles. A lack of vitamin D can lead to complications with the immune system, which can worsen the effects of the coronavirus if you get sick, several studies have shown. Vitamin D has long been believed to positively affect the immune response. A report recently published in Clinical Neurology News was published, emphasized the importance of the recommended daily dose of vitamin D for maintaining your immune system.


Using vitamin D can protect people from serious complications from COVID-19. Its scientific evidence is under further investigation. Studies in Belgium, among others, show that people with a vitamin deficiency are twice as likely to develop major complications if they become infected with the corona virus.

Researchers at Northwestern University concluded that severe outbreaks of COVID-19 in several countries can be linked to a vitamin D deficiency in the population. A study by the VU University Amsterdam also showed that countries with a low vitamin D content were also the countries with the highest death rates and most infections with COVID-19.

Vitamin D deficiency

In the winter months, many Dutch people have to deal with a vitamin D deficiency. Vitamin D is found in fish, among other things. But vitamin D is mainly produced after exposure to sunlight. In the winter months and if you stay indoors a lot, you will be less exposed to natural sunlight. That is why many Dutch people are advised to take vitamin D. Especially young children, the elderly, people with a medium skin color, people who rarely go outside and pregnant women are advised to take extra vitamin D.

Dark skin and vitamin D.

In Italy and Spain, countries also heavily affected by the coronavirus, vitamin D levels are also low, despite an abundance of sun. The researchers say this is partly because residents in southern Europe have darker skin pigmentation. This decreases the body’s ability to produce natural vitamin D.

The highest average levels of vitamin D are found in the Nordic countries. This is due to a higher consumption of cod liver oil and vitamin D supplements. In addition, vitamin D is often added to foods in Scandinavia. An Indonesian study of 780 people who tested positive for SARS-CoV-2 found that 98.9 percent of infected patients were found to be vitamin D deficient.

Staying indoors and vitamin D deficiency

In the UK, most of the vitamin D deficiency stems from a lack of sun exposure between the end of March and the end of September. However, during the lockdown, people stayed indoors much more and therefore had less chance of producing vitamin D themselves after March through exposure to daylight.

Whether vitamin D supplementation can reduce the risk of infection or the risk of death in European populations is not entirely clear, but there is now strong evidence of the positive effect of vitamin D.

Recommended dosage

Vitamin D tablets are inexpensive and vitamin D is recommended during lockdown. The NHS advises Britons to take extra vitamin D. The recommended dose is approximately 10 micrograms of vitamin D per day. Large doses of vitamin D are not recommended. Doses above 100 micrograms can be dangerous and should only be administered under medical supervision. Vitaminstore asked me to write an article about the vitamins.
