Vitamin D has a central and complex relationship with the functioning immune system. Vitamin D is important for everything from immune cell activation and modulation to inflammatory regulation, with direct influences on the lung epithelial cells and immune regulation in the lungs. Studies have shown a relationship between vitamin D levels and decreased risk of flu and other respiratory tract infections, including acute respiratory distress syndrome (ARDS), a main cause of death due to COVID-19.

Amidst the COVID-19 pandemic, vitamin D deficiency itself is a major health concern that must be addressed in order to boost immune responses and improve COVID-19 outcomes among all populations. Data has already been published showing a protective effect of vitamin D serum levels above 30 ng/ml against severe COVID-19 outcomes, and data on vitamin D and COVID-19 continues to be published showing a similar beneficial effect. One such study highlighted below shows how COVID-19 patients in a hospital in Singapore responded to supplementation with vitamin D, along with magnesium and vitamin B12.

Severe Outcomes Significantly Reduced in Patients Receiving Vitamins D, B12, and Magnesium

A pre-print publication (not yet peer-reviewed) by Tan et al. presents data of hospitalized COVID-19 patients over the age of 50 years who were either given an oral combination of vitamin D (1000 IU/day), Magnesium (150 mg/day), and Vitamin B12 (500 mcg/day), or not. Out of 43 consecutive COVID-19 patients who did not require oxygen therapy upon admission, 17 received the vitamin D, magnesium, and vitamin B12 (DMB) combination, while 26 patients did not.

The study found that those receiving the DMB combination were significantly less likely to require subsequent oxygen therapy or intensive care support, meaning that simply taking vitamin D, magnesium and vitamin B12 supported immune and lung function. Only 3 out of the 17 patients (18%) in the DMB group required subsequent oxygen therapy, two of which required the therapy within 24 hours after their first supplement dose. For the patients who did not receive supplementation, 16 of the 26 (62%) required subsequent oxygen therapy. There was a significant protective effect against clinical deterioration with the need for oxygen therapy for DMB supplementation, after adjusting for age (P=0.039) or hypertension (P=0.044) separately. No side effects were observed due to DMB supplementation.

Know if you are getting enough magnesium and other important nutrients!

Vitamin D, magnesium, along with zinc, omega-3s, and others, are just a few nutrients vital to maintaining many aspects of our health. The Magnesium PLUS Essential Elements test kit includes a simple blood spot test to measure these nutrients and more. To know if you are getting enough, make sure you test today!

We’re in a time of great crisis that could be greatly affected by making sure you and everyone you know has a serum level of at least 40 ng/ml. Help us help you.

Do you know what your vitamin D level is? Be sure to test today to find out, and take steps to keep it within a target of 40-60 ng/ml or 100-150 nmol/L! Give your immune system the nutrients it needs to support a healthy you and protect yourself from unnecessary diseases.

GrassrootsHealth Nutrient Research Institute is preparing to do a Community RCT with the use of our myData-myAnswers nutrient health system that over 15,000 people are already using for their health. We will demonstrate how one can use the Nutrient Research Model established by Dr. Robert Heaney to establish the effect of vitamin D serum levels of at least 40 ng/ml (100 nmol/L) on risk reduction with different ethnicities in the population. Please let us know if you’re interested in helping sponsor this project.

How can I track my nutrient intake and levels over time?

To help you track your supplement use and nutrient levels, GrassrootsHealth has created the Personal Health Nutrient Decision System called

For each specific supplement, you can track what days you take it, how much, and many other details.  This will help you know your true supplemental intake and what patterns of use work for you to reach and maintain optimum nutrient levels.  Check it out today!

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)
