The role vitamin D plays in the immune system response has received much coverage over the last several months. The issue seems more important now with the current coronavirus pandemic, on top of decades of research showing how vitamin D can be effective in reducing the risk of many types of acute respiratory tract infections. In fact, a systematic review published back in 2017 of vitamin D clinical trials involved over 11,000 participants, and found that those in a subgroup taking daily or weekly vitamin D supplements had a significant 19% reduction in risk of acute respiratory tract infections, but for those with baseline vitamin D levels of 10 ng/ml, the reduction was 70%. (A more detailed review of this publication is coming soon.)

But, has that information prompted you to find out your current vitamin D level? Or, possibly, to start supplementing with vitamin D? Or to take more than you were before? Are you still assuming your vitamin D level is “OK”?

Here is a great graphic to download and share with others to highlight the importance of vitamin D and what to consider when evaluating how you may be getting vitamin D with your lifestyle, diet, and intake.

What can affect how your vitamin D level responds to supplementation?

On occasion we have participants who experience a lower than expected vitamin D level. There are several factors that can influence how an individual responds to supplementation with vitamin D, and many other supplements. In an upcoming newsletter, we will explore possible causes of a low or slow to rise vitamin D response.

Are You Getting Enough Vitamin D to Help Yourself?

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.

Through GrassrootsHealth Nutrient Research Institute, you can also test your essential elements magnesium, copper, zinc and selenium, toxins such as lead, mercury and cadmium, as well as your omega-3 levels, inflammation levels and thyroid stimulating hormone (TSH) level. Find out your levels today! Log on to the test selection page (click the link below) to get your tests and see for yourself if your levels can be improved.

Make sure you track your results before and after, about every 6 months!

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)
