A special ‘Thank YOU’ to each and every one of you on this Thanksgiving Eve…

On the eve of Thanksgiving we would like to thank you, our participants and followers, our Scientists’ Panel, and our entire staff, especially for the focus on creating an expansion of the ‘Citizen Scientists’ role for all. YOU are doing it!

Some of the changes we have seen since we began D*action in 2007 are overwhelming! Can you imagine going into a grocery store or pharmacy and not finding a vitamin D supplement? Well, that was the case in 2007.

Can you imagine an insurance company acknowledging the benefits of vitamin D and even funding a project in their local area? Can you imagine a medical institution changing their standard of care to incorporate vitamin D testing and education for all of their prenatal patients? Can you imagine over 200 doctors and scientists from around the world joining together in a call to action to increase vitamin D intake and serum levels to at least 40-60 ng/ml (100-150 nmol/L) immediately to combat the COVID-19 pandemic, pushing the implementation of vitamin D testing for all patients? These things have happened and are now happening, in 2021 – and I am very thankful.

People are taking action in response to the vitamin D prevention message. It is hitting home. This may be because of the changes in insurance laws, or because we are all sick of our family and loved ones being diagnosed with diseases we now know can be prevented. Regardless of the cause, many more people are taking steps to prevent disease now in 2021 than in 2007 – and I am very thankful.

Our great GrassrootsHealth staff does so much for our organization that goes beyond their jobs. They all believe firmly in the cause and definitely show it with their ongoing dedication and efforts. And I am thankful for the scientists we are privileged to work with. Their science and their participation are the backbone of the organization. Our staff and some of our panel scientists are working together tirelessly to spread the word about vitamin D, other nutrients, our immune health, and COVID-19 especially, to help save lives and lessen sickness – and I am very thankful.

And I am very thankful for the persistence of all participants who have seen the educational value of testing over time, how the changes in health are influenced, and the added value it gives to everyone being in the role of a Citizen Scientist—being involved in the research while taking charge of their own health.

We are living a life of thankfulness each and every day! Moving Research into Practice is being achieved through your participation – a very special joy for all!

Have a very special Thanksgiving day!

Become a Citizen Scientist and Measure Your Nutrient Levels Today!

Having and maintaining healthy vitamin D and other nutrient levels can help improve your health now and for your future. Choose which to measure, such as your vitamin D, omega-3s, and essential minerals including magnesium and zinc, by creating your custom home test kit today. Add hs-CRP to measure your level of inflammation as well.  Take steps to improve the status of each of these measurements to benefit your overall health. You can also track your own intakes, symptoms and results to see what works best for YOU.

Enroll and test your levels today, learn what steps to take to improve your status of vitamin D (see below) and other nutrients and blood markers, and take action! By enrolling in the GrassrootsHealth projects, you are not only contributing valuable information to everyone, you are also gaining knowledge about how you could improve your own health through measuring and tracking your nutrient status, and educating yourself on how to improve it.

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!
