Every day we are thankful for the scientists who helped provide the initial scientific backbone and have provided their ongoing commitment to sharing their information and expertise with GrassrootsHealth because they want it to be shared with you! We are also thankful for all the individual participants who have gotten involved in this truly unique project to ‘Move Research into Practice’ by taking the time to learn more about the health effects of vitamin D, of omega-3s, and magnesium, AND their interactions with each other in helping to contribute to health.

I’d like to introduce you to the group of researchers who put on our very first vitamin D seminar and have been instrumental in continuing to help address the very significant public health issues!

List of Vitamin D Researchers in Photo, left to right: Candace Johnson, PhD, Roswell Park Cancer Center; Michael F. Holick, MD, PhD, Boston University; Donald L. Trump, MD, Roswell Park Cancer Center; Cedric F. Garland, Dr. P.H., F.A.C.E., UCSD; Frank C. Garland, PhD, NRTC*; David C. Sane, MD, F.A.C.P.; Robert P. Heaney, MD, Creighton University*; William B. Grant, PhD, Sunlight Institute; Anthony W. Norman, UCR*; Edward D. Gorham, PHD, UCSD, NRTC; Carole A Baggerly, Director, GrassrootsHealth.


There are 3 of these great people who are no longer with us who deserve a special note of thankfulness as well, Dr. Frank Garland* (5th from left), Dr. Robert P. Heaney* (7th from left), and recently, Dr. Anthony Norman* (9th from left).

Shortly after the formation of GrassrootsHealth, my husband, Dr. Leo Baggerly, one of our researchers as well, toured the US and Canada with me to meet even more vitamin D experts! We now have 48 from around the world on our panel of experts.

What’s Next for the GrassrootsHealth Nutrient Research Institute?

  • Expansion of offerings of myData-myAnswers to its participants, to allow targeted reporting, custom answers/reports for personal health
  • Expansion of Projects with Medical Offices to demonstrate Scientific Data about the Efficacy of their Treatments–answering ‘How does it work for me?’ for both patients and practitioners
  • Provision of special modules with myData-myAnswers to be used as a practitioner module for the implementation of special projects, e.g., Type 1 Diabetes Prevention, Cardiac Health, Healthy Pregnancies, Cancer Prevention, Ketogenic Diets, Pediatric Practices, to all practitioners who are ready to use science and technology to ‘Move Research into Practice’
  • Nutrient Research Methodology Continuing Education Courses to provide researchers/statisticians a consistent methodology to enhance the repeatability of the results, to avoid the challenges of inconsistency of results due to method
  • Establishment of a Donor Opportunity to help sponsor key projects, publication of research from our participants and development of Public Relations/Outreach of those findings

Of course, we are always thankful for your donations, to help us expand our offerings to help you be healthy, to help your friends and associates be healthy, to help prevent diseases and expensive treatments!

A very special Thank YOU to you, for all your work in helping spread the word.

Important Message

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

EVERYONE needs to know about the benefits of vitamin D... We need your help to do this. Donating $25.00 today will positively affect millions of lives!

We will take this opportunity to use our extensive network to get pertinent information on vitamin D to the new US COVID Panel as well as local and state government representatives around the world.

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!). You can also "text-to-give" by simply texting Daction to 44321.

Donations made through GiveLively are received in full by GrassrootsHealth.

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!
