Amongst the challenges we have faced this year and continue to face, we hope that you are able to find some holiday cheer and gratitude for the wonders and joys that remain in our lives. At GrassrootsHealth, we are especially grateful for all of our participants, for your continued participation and support, as well as the scientists and researchers who have worked diligently to spread the word about vitamin D – some for decades – only to make small strides forward at a time. We KNOW the health benefits of achieving our scientists’ recommended levels of vitamin D (40-60 ng/ml or 100-150 nmol/L). From reducing the risk of cancer, diabetes, heart disease, preterm birth and pregnancy complications, dementia, and especially amidst the COVID pandemic, respiratory infections, including COVID-19 itself.

Vitamin D is absolutely essential to our health! Thanks to all of you, we are able to continue to make that a realization for ALL.

Have you shared the message that vitamin D matters – not just your intake, but your serum level?

Everyone responds differently to supplementation, and the amount we need is unique to each of us. Make it easy for you and your loved ones to know your level by testing with our home blood spot test kits; you can now share this gift with others this holiday season with our new gift cards! And, once you test, take the steps necessary to achieve your target vitamin D level, starting with our newly improved D*calculator.

Check out our 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.

Happy, Healthy Holidays to all of YOU!
From the GrassrootsHealth Team

Enjoy Life with a New Point of View!

Sometimes a ‘new point of view’ (even upside down) helps bring about new joys, new beginnings! We have seen this year a major new point of view from our project participants, our project partners, and especially with the increased demand to STAY HEALTHY. It’s a joy to help provide some of those essential components, tools, and education for you to take charge of your own health.

Enjoy, share, and smile. Blessings to you all. Thanks so much for your participation in the world’s largest crowd-funded health research project.

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!
