PLUS, the Vitamin D & COVID-19: A Summary of Published Research eBook is now available in its first version!

Key Points

  • There is much evidence showing the significant effect that vitamin D status has on COVID-19 disease progression and outcomes, where higher vitamin D levels can reduce the risk of infection and severity and help prevent death
  • Vitamin D plays roles within the immune response that are especially influential in fighting a SARS-CoV-2 (COVID-19) infection
  • Share this knowledge easily with the new Vitamin D & COVID-19: A Summary of Published Research eBook, available now for purchase

 

How Vitamin D Works to Fight COVID-19

A number of studies, such as those included in our new eBook, have provided much evidence showing the significant effect that vitamin D status has on COVID-19 disease progression and outcomes, where higher vitamin D levels can reduce the risk of infection and severity and help prevent death. How does vitamin D work within the body to have such a protective effect?

The following diagram by Ghelani et al. is an excellent illustration of how the presence or absence of vitamin D could determine the overall effect a SARS-CoV-2 infection has within the lungs and on disease progression. As shown in blue, vitamin D sufficiency can help protect the lungs from acute injury due to infection from SARS-CoV-2, while vitamin D deficiency contributes to a defective immune response and increased disease severity and death, as illustrated in orange.

Vitamin D plays roles within the immune response that are especially influential in fighting a SARS-CoV-2 (COVID-19) infection

Infection begins when the SARS-CoV-2 virus enters the cells of the lung by binding the angiotensin-converting enzyme 2 (ACE-2) receptor, de-activating it and resulting in inflammation. This interrupts what is called the renin-angiotensin system (RAAS), a pathway responsible for regulating blood volume, fluid and electrolyte balance, and systemic vascular resistance.

When vitamin D is available in sufficient amounts, it is able to fulfill its roles to

  • regulate the renin-angiotensin system (RAAS)
  • increase ACE-2 expression, which leads to anti-inflammatory actions that help protect the lungs, keep inflammation levels down, and reduce the risk of cytokine storm
  • prevent the toxic accumulation of the pro-inflammatory molecule angiotensin-II (ANG II) and angiotensin-converting enzyme (ACE)
  • increase immune cells with antioxidant properties, anti-inflammatory actions, and anti-microbial peptides through its actions within the immune system

With additional research showing that

  • vitamin D receptors are found in high concentrations in various immune cells that are vital to a successful immune response, especially dendritic cells, macrophages, T and B lymphocytes
  • the enzyme that converts 25(OH)D3 into 1,25(OH)2D3 is present in high levels in macrophages and the epithelia of the respiratory system specifically
  • and, vitamin D has been found to disrupt the function of 19 out of 27 (70%) SARS-CoV-2 proteins

It’s no wonder that “…low levels of vitamin D can result in dysfunction of crucial antimicrobial effects, potentially contributing to poor prognosis.”

By enrolling in the GrassrootsHealth projects, you are not only contributing valuable information to everyone, you are also gaining knowledge about how you could improve your own health through measuring and tracking your nutrient status, and educating yourself on how to improve it.

How Can You Use this Information for YOUR Health?

Having and maintaining healthy vitamin D and other nutrient levels can help improve your health now and for your future. Measuring is the only way to make sure you are getting enough!

STEP 1 Order your at-home blood spot test kit to measure vitamin D and other nutrients of concern to you, such as omega-3s, magnesium, essential and toxic elements (zinc, copper, selenium, lead, cadmium, mercury); include hsCRP as a marker of inflammation or HbA1c for blood sugar health

STEP 2 Answer the online questionnaire as part of the GrassrootsHealth study

STEP 3 Using our educational materials and tools (such as our dose calculators), assess your results to determine if you are in your desired target range or if actions should be taken to get there

STEP 4 After 3-6 months of implementing your changes, re-test to see if you have achieved your target level(s)
