Health: The Benefits of Vitamin D on Covid-19

A remedy for Covid-19: vitamin D

For several months now, Covid-19 has been wreaking havoc. For a long time without a fixed solution, researchers have managed to prove that vitamin D could have positive effects on this disease. What then are the benefits of this substance on the pandemic ?

Preventing infection by SARS-Cov-2: benefits of vitamin D

Since the arrival of the coronavirus, researchers have not given up and have set out to find a reliable solution that can eradicate the presence of this ailment. During their quest, they understood that taking vitamin D supplements could have a preventive effect against Covid-19.

Indeed, the presence of vitamin D, regardless of its quantity, affects the immune system of the human being. Thus, in a situation of vitamin D deficiency (circulating concentration of 2 [OH] D less than 0 nmol/L), the body reacts by developing risk factors.

This same fact is also observed when it comes to a vitamin D insufficiency characterized by a circulating concentration of 2 (OH) between 12 and 20 ng/mL.

Furthermore, it is proven that vitamin D strengthens the defenses of the mucous membranes by stimulating the expression and secretion of antimicrobial peptides. It also inhibits the secretion of pro-inflammatory cytokines through the synthesis of anti-inflammatory cytokines.

Aside from these data, scientists have deepened their research by conducting observational studies and meta-analyses of controlled randomized trials. At the end of these examinations, it was proven that supplementation with vitamin D has a protective effect on respiratory tract infections in particular. However, how do all these pieces of information prove the effectiveness of vitamin D on Covid-19 ?

Effects of vitamin D on Covid-19 victims

In reality, after the infection of the first victims of the coronavirus, analyses showed, particularly in adults, a low circulating concentration of 2 (OH) D. An ecological study conducted in 46 countries also revealed that Covid-19 occurred following a deficiency in vitamin D.

In general, these various results highlight the importance of vitamin D supplementation. The more vitamin D present in a person, the higher the circulating concentration of 2 (OH), and the more resistant their body is to the infection of SARS-Cov-2.

To summarize, taking vitamin D supplements could help the population better prepare their bodies to be resistant to Covid-19. Of course, this is merely a suggestion. It does not exclude the adherence to hygiene rules and other preventive measures to reduce the risks of contamination.

Preventing the occurrence of severe forms of Covid-19

After the infection by coronavirus, two scenarios remain possible. Either the victim presents mild symptoms, or the virus progresses to a severe form characterized by an uncontrolled inflammatory reaction.
Called a “cytokine storm,” this second form of covid-19 causes severe tissue damage accompanied by a pro-inflammatory state. It is often fatal for victims who present these symptoms, especially with the onset of ARDS (acute respiratory distress syndrome).

People susceptible to this form are often those who have a severe deficiency in vitamin D, such as the elderly. Diabetics and obese individuals can also exhibit this form of Covid-19. Moreover, it is worth noting that the factors of risks of severe forms of Covid-19 are very similar to those resulting from a deficiency in vitamin D.

However, with vitamin D supplementation, the risk of developing these symptoms is considerably reduced. This substance proves to be useful not only for preventing the coronavirus. Even after infections, you can nourish your body with vitamin D to reduce effects and avoid the development of a severe form.

How to improve your vitamin D intake ?

Given all these benefits of vitamin D, we recommend increasing the intake of this substance in your body. It is possible to follow certain ideas.
First of all, vitamin D is a substance that the skin produces on its own. To allow it to quickly achieve this goal, it must be exposed to sunlight. This action enables it to optimize the production of vitamin D, and thus improve its intake in the body.

Aside from this production by the skin, it is also possible to access this vitamin by opting for the consumption of foods. Thus, to increase the intake of vitamin D in the body, it is advisable to consume fatty fish such as sardines and herring.

In addition to fish, breakfast cereals, certain milks, and oils are also foods that contain a high content of vitamin D. Therefore, to optimize the intake of this substance, it suffices to expose yourself to the sun two to three times a week while keeping an eye on your diet.
Moreover, taking vitamin D supplements is also an excellent solution to promote the intake of this substance. For this purpose, it is sufficient to purchase one while remembering to respect the required quantities.

The benefits of vitamin D: a remedy against Covid-19

Studies demonstrate a certain effectiveness of vitamin D in the prevention of certain cancers, such as diseases and diabetes, involving the immune system. It is known that vitamin D plays a role in protecting against heart diseases. Thus, vitamin D is a true remedy against Covid-19.

What are the foods rich in vitamin D?

There are few dietary sources of vitamin D. It is mainly found in fatty fish such as tuna, herring, or salmon. Additionally, beverages, milk, soy eggs, and beef liver contain it.

When to take vitamin D, morning or evening?

As of today, vitamin D professionals do not indicate a specific time for taking it, but in-depth analysis has proven that vitamin D supplements should be taken during meals to stimulate absorption.

What is the fruit richest in vitamin D?

The fruit richest in vitamin D is papaya, along with oranges: orange juice, and kiwi.
