What is Vitamin D Good For? (Part 5: Respiratory Health) – Vitamin D is needed by virtually every cell in the body, and is essential for hundreds of processes each and every day

Previously, as part of our What is Vitamin D Good For? series, we have covered many different ways vitamin D contributes to the health of multiple systems within the body. Vitamin D acts as a protector and regulator so it is able to enhance the functioning of all types of cells, tissues and organs to keep us healthy. So far, we have covered how vitamin D contributes to the health of the musculoskeletal system, dermatological system, reproductive system, and to cognitive and mental-emotional wellness. A deficit in vitamin D can lead to impairment or disease in each of these systems – from brittle bones to heart disease, cancer and dementia. With this in mind, why take a chance at being deficient in vitamin D?

Today, we take a look at why vitamin D is important to the health and function of the lungs and respiratory system.

Summary of Overall Benefits of Vitamin D for Respiratory Health

Vitamin D functions in the respiratory system to:

  • Protect against infection
  • Support immune cell function (white blood cells) in the throat, airways and lungs
  • Help regenerate the protective endothelial barriers
  • Regulate the inflammatory response and prevent cytokine storm

Respiratory Diseases associated with low vitamin D include:

Vitamin D Functions to Directly Protect the Lungs

Vitamin D acts to directly protect the lungs, from its effect on the protective barrier of the lungs, to its involvement in the maturation of immune cells, and its role in regulating the inflammatory response and inhibiting the cytokine storm. Cellular models have demonstrated the direct effect of vitamin D deficiency on the tissues within the lungs, which include increased alveolar inflammation, lung epithelial damage, and hypoxia (the deprivation of oxygen to surrounding tissues). This helps explain why vitamin D deficiency has been associated with an increased risk of developing pneumonia, Acute Respiratory Distress Syndrome (ARDS, aka wet lung), and sepsis, and why correcting vitamin D deficiency may help prevent damage to the lungs, such as when addressed prior to procedures of the upper respiratory tract such as oesophagectomy (surgery to the esophagus).

Vitamin D Deficiency Contributes to ARDS

ARDS is currently a major complication and cause of death among those with serious COVID-19 infections. Vitamin D seems to play a role in reducing ARDS and the severity and death due to COVID-19. The graphic below illustrates what happens in the lungs during ARDS, in which the air sacs of the lungs fill with fluid, preventing the uptake of oxygen. The condition leads to shortness of breath and difficulty breathing, and in severe cases, can lead to sepsis and/or death. Vitamin D helps to modulate inflammation and over-reaction of the immune response, therefore reducing the risk.

Vitamin D Helps Fight Respiratory Tract Infections – Decreasing Risk by up to 70%

Vitamin D has also been shown to reduce the risk of other types of acute respiratory tract infections. In a meta-analysis published in 2017, Martineau et al. set out to assess the effect of vitamin D supplementation on the risk of acute respiratory tract infection (RTIs). The review included 25 randomized, double-blinded, placebo controlled trials (RCTs), with a total of 11,321 individual participants. They found that vitamin D supplementation resulted in a statistically significant reduction in risk of RTIs among all participants, with a 12% lower risk of acute RTIs for those supplementing with vitamin D versus those with no supplementation. Even greater protective effects were seen among those receiving daily or weekly vitamin D supplements without additional bolus doses of 30,000 IU or larger.

The greatest protective effect was seen among participants who received daily or weekly supplementation and whose starting vitamin D level was less than 10 ng/ml (25 nmol/L), with a 70% decreased risk of acute RTI with vitamin D supplementation compared to a 25% reduction for those whose starting levels were greater than 10 ng/ml.

Publication of the Role of Vitamin D in Viral Respiratory Infections

For more in-depth reading, GrassrootsHealth, in collaboration with D*action Scientist Panel Member Dr. William Grant and others, have published a paper titled Evidence that Vitamin D Supplementation Could Reduce Risk of Influenza and COVID-19 Infections and Deaths. This paper is a review of the current research around the role of vitamin D in immune function, specifically in response to viral infections of the respiratory system. It outlines the relationship between vitamin D serum levels and the incidence of seasonal flu, as well as past epidemics such as those caused by the SARS and MERS coronaviruses. High risk conditions, the progression of illness, and mechanisms and proposed actions of vitamin D during the immune response are also reviewed.

Other Important Co-Nutrients for Respiratory Health

Don’t forget that vitamin D works along with other essential nutrients for our health. For our respiratory health, these include:

Are You Getting Enough Vitamin D and Other Nutrients to Support a Healthy Respiratory System?

With almost 90% of the general population having vitamin D levels below the recommended 40-60 ng/ml (100-150 nmol/L), it is obvious that most people need more vitamin D. While most of us cannot achieve a vitamin D level of 40-60 ng/ml from sun alone, either due to our lifestyle, where we live, or other circumstances, we can certainly reach those levels with the right amount of supplementation.

Below is a guide for how much you might need, and who may need more. Your levels can be tested safely at home – order your home test kit today.

What does the Research Say about Vitamin D & COVID-19?

It’s TIME to start saving lives! If you can help PREVENT the majority of the death, it’s time! What’s it costing you/us not to take action NOW?

There is much published research that supports a clear link between vitamin D and COVID-19 showing that higher vitamin D levels are related to:

a decreased risk of testing positive for COVID-19

increased viral SARS-CoV-2 RNA clearance

better clinical outcomes among patients with COVID-19

less severe COVID-19 disease

decreased risk of death due to COVID-19

Be sure to educate yourself on the benefits and importance of vitamin D for immune health, and take steps to ensure you and your loved ones are getting enough.

STEP 5 – Re-Test! This is an important step to make sure you have reached your target level, and to ensure you are not taking too much! Re-testing after 3-4 months is recommended.

STEP 6 – Adjust, Repeat…

Give your immune system the nutrients it needs to support a healthy you and protect yourself from unnecessary diseases, especially COVID-19.

NEWS ALERT

The first Randomized Controlled Trial on vitamin D and COVID-19 has shown a 96% lower risk of ICU admission for those receiving vitamin D (as 25(OH)D to quickly boost vitamin D blood levels) along with the standard treatment, compared to those receiving standard treatment alone.

These results support many previous observational studies showing a relationship between vitamin D levels and intake and COVID-19 severity.

Review the Latest Nutrient Research for COVID-19

GrassrootsHealth Nutrient Research Institute has launched the new Immune Boost project with the use of our myData-myAnswers nutrient health system that nearly 15,000 people are already using for their health. Specific markers that influence immune health are suggested for testing as part of this project including:

  • Vitamin D
  • Omega-3 Index
  • Essential elements magnesium, selenium, and zinc
  • hsCRP

Our goal is to demonstrate how one can use the Nutrient Research Model established by Dr. Robert Heaney to show the effect of vitamin D serum levels of at least 40 ng/ml (100 nmol/L) on risk reduction for all ethnicities in the population. Status and intake of other nutrients will also be analyzed for any type of relationship to immune status and symptom severity. Join the project today!
