Vitaminfood’s role in battling Covid-19

It is already established that Vitaminfood meal replacement shakes can play a key role in your health. Is it now not even better that it could help battle and keep off SARS-Cov2 virus. Vitaminfood complete nutrition could be the difference you need to be fairer than the general population. Let us see how.


Vitamin D is the clincher here; it is the deal-maker. Several recent studies all done in the course of this year have shown that there is a significant correlation between the mean vitamin D levels and the number of cases of COVID-19 in the population studied. This correlation also extends to the number of cases requiring intensive care and number of deaths.


What this all means is that the right quantity of vitamin D and good timing of supplements could save you from catastrophes. Vitaminfood meal shakes give you the right amount of Vitamin D to hit your recommended daily intake alongside your diet.


Vitamin D benefits regarding Covid-19


This “sunshine vitamin” has for a long time been known for its purpose strong bone development. It is useful in the absorption of calcium and phosphorous and their utilization by the body. It has also been shown to play a part in preventing certain types of cancers.


Previous studies have also revealed that Vitamin D reduces Acute Respiratory Distress Syndrome. It prevents against acute respiratory infections and dangerous complications of the respiratory tract.

In regards to Covid-19 patients researched, Vitamin D had the following impact:

  1. To those whom a highly potent form was administered, the number of patients who needed intensive care was significantly lower and so were the death rates.
  2. Patients with sufficient Vitamin D were less likely to face dangerous complications of advanced stages of infection like difficulty in breathing, unconsciousness and hypoxia
  3. Those deficient are more likely to get infected in the first place. They have 54% greater likelihood of getting infected if exposed than those with sufficient Vitamin D.
  4. Supplements are most effective if administered in early stages before illnesses worsen.


Vitamin D Deficiency


The healthy and normal quantities of Vitamin D are as shown in the table below:



Blood test result


30 nmol/l or 12 ng/ml or below


50 nmol/l or 20 ng/ml or above


125 nmol/l or 50 ng/ml or above


(nanometers per mole or Nanograms per millilitre)


The medical data shows that Vitamin D deficiency is severely widespread especially across Europe and North America. Even in those countries with most dairy products fortified with Vitamin D, the people still rarely meet the Vitamin D bodily requirements. As many as 50% of Europeans suffer from Vitamin D deficiency.


Special groups like the elderly and the obese are more affected. The elderly have up to 80% deficiency and the obese need up to 3X the normal amounts. For the elderly, skin degeneration reduces its efficiency in Vitamin D production causing a deficiency in the D3. For the obese, the high number of fat cells bind to the Vitamin D preventing it from entry into the cell where it is needed.


These groups are especially prone to deficiency and the effects of being deficient. So extreme is this that various doctors advocate for Vitamin D supplementation and its use fortifying common products like bread and milk. Countries like Switzerland, Spain and Italy were specifically noted to be greatly affected.


Get some Vitaminfood for Vitamin D


Would you however choose fortified products and consume a lot more toxins and unhealthy ingredients from them. This will most likely cancel out the effect of Vitamin D because the same product that fortifies also breaks down the immune system.


Get yourself some Vitaminfood, the healthy meal replacement for your Vitamin D boost. Vitamin D supplementation is a universal counsel given even by World Health Organization leaders and prominent researchers and doctors.


The deficiency increases during the winter seasons because of the reduced exposure to sunlight. With all the cloudiness and the time spent indoors during winter, getting the natural sunlight for Vitamin D3 is almost impossible. This D3 is the more common form of Vitamin D metabolite synthesized by the skin but this is hindered by winter conditions and adaptations. Vitaminfood is here to help you out this winter period.

You’ve got to add your Vitamin D supplementation for immune protection and Vitaminfood is one great way to hit this goal.


Vitamin D as a hormone


Vitamin D is a hormone the kidneys produce that controls blood calcium concentration and impacts the immune system. It is also known as calcitriol, ergocalciferol, calcidiol and cholecalciferol. Of those, cholecalciferol(D3) is the form doctors most commonly focus on when measuring vitamin D levels in the blood. Vitamin D has its effects by binding to a protein (called the vitamin D receptor). This receptor is present in nearly every cell and affects many different body processes. 



Vitamin D supplementation to prevent acute respiratory tract infections: systematic review and meta-analysis of individual participant data

One study carried out on randomized, double-blind, placebo-controlled trials of supplementation with Vitamin D proves this.

The results from more than 10,000 participants aged 0 to 65 years were obtained. Vitamin D supplementation truly reduced the risk of acute respiratory tract infection among the participants. In sub group analysis, protective effects were seen in those receiving the regular dose of Vitamin D up to a threshold amount beyond which the effect was not observed.

Among those in whom the effect was observed, those with severe deficiency experienced the most benefits while those with normal amounts experienced the impact too but to a lesser extent. 

The supplementation was considered safe for the participants with less than 0.1% registering any consequence which was however mild and short-lived like vomiting.

Observational data shows that there is a causation and correlation between these two factors. There exists independent associations between low serum concentrations of D3 vitamin and susceptibility to ARDS.



Vitamin D interaction with its receptors in immune cells modulates the innate and acquired immune systems in response to the invasion of bacterial and viral pathogens.

25-hydroxyvitamin D supports induction of antimicrobial peptides in response to both viral and bacterial stimuli. This induces protection against respiratory tract pathogens and their development in the upper respiratory tract.  Vitamin D metabolites have also been reported to induce other innate antimicrobial effector mechanisms, including induction of autophagy and synthesis of reactive nitrogen intermediates and reactive oxygen intermediates.

  1. Control cytokine storm which is the release of too many proteins in the blood too quickly. This often leads to Acute Respiratory Distress Syndrome that causes mortality in most cases. Vitamin D modulates the serum CRP which is the reactive protein preventing this life-threatening condition.
  2. Regulates the angiotensin pathway and down regulates the ACE2.

Renin is secreted by the juxtaglomerular cells of the kidney in response to decreased renal blood flow. It converts plasma angiotensinogen to angiotensin I, which is then converted to angiotensin II by the angiotensin-converting enzyme. Angiotensin II leads to increased water and sodium reabsorption in the kidney and vasoconstriction. Mounting evidence indicates that vitamin D regulates the renin-angiotensin system.

The renin-angiotensin system affects inflammation and immunity and by regulating it, Vitamin D helps maintain a healthy immune system.

  1. Anti-inflammatory effect -Vitamin D is not a suppressor of the immune system but rather modulatory by reducing inflammation.

Vitamin D has recently been found to play an important role in the modulation of the immune/inflammation system via regulating the production of inflammatory cytokines and inhibiting the proliferation of pro-inflammatory cells, both of which are crucial for the pathogenesis of inflammatory diseases. In acute infection and autoimmune disorders, preliminary evidence suggests an important role of vitamin D supplementation in decreasing the risk of disease.

Vitamin D [1,25-dihydroxyvitamin D; 1,25(OH)2D] has been shown to have immunomodulatory activity, and it has previously been suggested that the vitamin could have a protective effect against COVID-19


Vitamin D supplementation reduced the risk of experiencing at least one acute respiratory tract infection. Subgroup analysis revealed that daily or weekly vitamin D supplementation without additional bolus doses protected against acute respiratory tract infection, whereas regimens containing large bolus doses did not. Among those receiving daily or weekly vitamin D, protective effects were strongest in those with profound vitamin D deficiency at baseline, although those with higher baseline 25-hydroxyvitamin D concentrations also experienced benefit. 

A different Seneca study carried out in European locations


“The Seneca study showed a mean serum vitamin D of 26nmol/L in Spain, 28 nmol/L in Italy and 45 nmol/L in the Nordic countries, in older people [3]. Severe deficiency is defined as a serum 25(OH)D lower than 30nmol/L [3]. In Switzerland, mean vitamin D levels are 23(nmol/L) in nursing homes and in Italy 76% of women over 70 years of age have been found to have circulating levels below 30nmol/L [3]. These are countries with high number of cases of COVID–19 and the aging people is the group with the highest risk for morbidity and mortality with SARS-Cov2.

Martineau AR et al concluded in a meta-analysis that vitamin D supplementation was safe and protective against acute respiratory tract infections. They described that patients who were severe vitamin D deficient experienced the most benefit [5].

In conclusion, we found significant relationships between vitamin D levels and the number COVID–19 cases and especially the mortality caused by this infection. The most vulnerable group of population for COVID–19 is also the one that has the most deficit in Vitamin D.”





There is conclusive evidence that Vitamin D plays a significant role in acute respiratory disease prevention and control, so does it with Corona Virus. Some of this evidence has been shared and more studies to verify this are being done.
