Can vitamin D help against the Coronavirus infection?

Looking at the facts, Vitamin D has a strong impact on the health of the upper respiratory tract and prevents acute lung infections (also called pneumonia) or it can reduce the symptoms of infection.

FOR COVID-19, we know that it becomes dangerous when it causes a difficult lung infection and the patient actually “suffocates”. The prevention or reduction of symptoms of respiratory infections can therefore save lives and facilitate the recovery after an coronavirus infection.

Social isolation and hand washing are probably the best methods for preventing coronavirus infections, but it is regrettably assumed that COVID-19 will infect between 40 and 70 of all population, which means that you are likely to become infectedwith it in the future.

Vitamin D, with its positive impact on the immune system, reduces your chance to get sick even if you accidentally get in contact with the virus.

The positive properties of vitamin D are also reported by Slovenian physicians

Dr. Darko Siuka, gastroenterologist says:

“Several studies point to the positive effect of vitamin D in the fight against infection. This lowers the number of ACE2 receptors on the surface of the pulmonary cells, through witch the virus enters the cell. It affects the higher concentration of surfactants, substances that surround the pulmonary follicles from the inside. The study shows that severe pulmonary impairment occurs only in patients with a deficiency of D-vitamin. In the winter months almost everybody is deficient in it. In particular, elderly, male, diabetic and other chronic patients are at risk. Vitamin D deficiency coincides with risk groups for Covid-19. Also sufficient levels of vitamin C, zinc and selenium are important.

Vitamin D and viruses

The most common viruses in humans are the flu and cold virus. The Corona virus does not differ significantly from the influenza virus, which is why it is subject to similar assumptions as the flu.

Most commonly, infections with viruses occur in cold months and are decreasing in summer. On the basis of these phenomena for 20 years there has been a hypothesis that viral disorders are directly relatedto the sun. Recently an article was published that connects this sunlight directly to vitamin D, which could be at least a partial culprit for virus epidemic during the winter months. The study sets out the facts:

  • Vitamin D levels are the lowest in winter months,
  • Vitamin D regulates the harmful inflammatory response of white blood cells and stimulates immune cells,
  • Children with vitamin D deficiency are more prone to respiratory infections, while children who are more in the sun are less likely to get sick.
  • Adults with low levels of vitamin D more frequently report cold, cough and upper respiratory tract infections.

Adding vitamin D decreases the acute upper respiratory tract infection by 12 to 75 depending on which study you look at. The benefits were in all age groups. Among those who were ill, the recovery time was shorter and with fewer symptoms if patients were taking 1,000 IU of vitamin D.

Do I have vitamin D deficiency?

Vitamin D deficiency is common. The farther away from the equator we are less strong the sun becomes, the less vitamin D we produce. The deficiency is also increasing with age and overweight.

NHANES study from the US reports that approximately 80% hospitalized elderly, have vitamin D deficiency.

The latest information comes from Ireland. In the study published in the Irish Medical party reported overt vitamin D deficiency in 27 of all persons over the age of 70 years.

Almost nobody reaches the optimum levels (50-60 ng/dl) if he’s not add vitamin D as a dietary supplement. This applies especially if your body weight is not exactly optimal.

Which vitamin D and what amount to fight the COVID-19?

For a sufficient amount of vitamin D, we recommend that you expose yourself to the strong sun. Morning and evening sun does not produce vitamin D in your skin. Do not use a sunscreen.

A diet that is rich in vitamin D includes high-quality fatty fish and quality cod liver fish oil, free-range eggs and fat of pigs that “sunbathe”. Lard of pigs that are raised indoors does not contain vitamin D.

For an additional benefit you can use vitamin D in capsules. For vitamin D, the quality and absorption is relatively good so there is no need for special liposomal sprays or similar. We recommend that you find quality softgel capsules of vitamin D3 (vitamin D2 is strictly to be avoided).

There are many different potencies the market ranging from 400 IU to 10,000 IU and above.

If you think you have a vitamin D deficiency it is recommended taking 10,000 IU daily up to a maximum of 2 months and then reducing the dose to less than 5,000 IU per day. Vitamin D can also be taken every other day (e.g. instead of 5,000 IE daily 10,000 IU every other day) or even only once a week in a combined dose. This will allow you to save when buying a higher potency.

Vitamin D is a fat-soluble vitamin. For better absorption, therefore, you should consume it with food.
