Vitamin D*action has achieved a major milestone: ‘Moving Research into PRACTICE’ is now a reality! States, Governments Acknowledge the Need for Vitamin D to Build the Immune System

This holiday season is unlike any other. As we move into the New Year, we wish you moments of peace, connections with family and friends even if they can’t be there in person, the warmth of memories from holidays past, and wonderful glimpses of the light that 2021 will surely bring.

This is YOUR year. You have taken charge of your health by expanding your knowledge
about vitamin D (with our help with the science), by testing, reporting and learning about how it influences your health. You are truly spreading the word throughout the world, and I congratulate you!

Today, we are announcing a NEW GIFTING SERVICE that allows you to quickly send ‘Gift Cards’ to friends, family and coworkers who you consider might need immediate access to testing, and to Claim the Joy of Your Health TODAY.

The GrassrootsHealth’s team and scientists have contributed tremendous efforts in making sure we create the informative resources our Vitamin D community enjoys. I am delighted to be personally involved in making sure that the word of health and Vitamin D is widely spread.

I want to take this opportunity to share yet one more accomplishment. With your participation, our work has now led to over 100 scientists, doctors, & leading authorities to take action and demand Vitamin D be included in public health efforts to combat COVID-19 health outcomes. Evidence so far suggests that 50 ng/ml (125 nmol/L) of vitamin D helps reduce infections, hospitalizations, ICU admissions, and deaths. It sets a clear sense of urgency to continue gathering more data on the health benefits of vitamin D. Over 180 research papers were written, comprehensively reviewed and endorsed by scientists around the world, including the US, Canada, Germany, Austria, Switzerland, Australia, New Zealand and more than 10 international organizations.

During this difficult year, I recognize that there is still a steep road ahead. Both you and I are aware that the information regarding the benefits of vitamin D are not only missing from public health forums but that, in many instances, the information can be either wrong, or misleading. This has led to some negative information. I am greatly encouraged by the growing knowledge of how the research has to be done to show correct research results to avoid this confusing information.

You have heard me before: The time to do a massive outreach push to share what you know with all is NOW! This is the kind of information we need to make sure everyone in the world understands and takes advantage of. We have the research. We have the data. We have the scientific community support. You have us to help you!

From the GrassrootsHealth team, we’d like to share with you a peaceful and healthy holiday season.

Donate $25 today to help support this outreach effort (and, let us know if your employer could match the donations made by individuals from now until January 1, 2021!).

What Does it Take YOU to Get Your D to 40 ng/ml (100 nmol/L)?

Did you know your health could be greatly affected by making sure you have a vitamin D level of at least 40 ng/ml (100 nmol/L)? Help us help you.

STEP 1 - Do you know what your vitamin D level is? If not, be sure to test today to find out.

STEP 2 – Determine your target level. Are you at your target level? Experts recommend a level of at least 40-60 ng/ml (100-150 nmol/L).

STEP 3 – Need to boost your level? Use the D*calculator to see how much vitamin D it may take to reach your target. Opt for the Loading Dose for a quicker boost.

STEP 4 – Optimize how your body absorbs and utilizes vitamin D with co-nutrients and these simple steps.

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.


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!

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!
