Those who follow GrassrootsHealth should be well aware that

But that’s not all… 46% of us do not get enough Vitamin C, 35% have inadequate vitamin A intakes, a whopping 84% do not get enough Vitamin E and 15% are inadequate for zinc, all of which are necessary for a healthy immune response.

Don’t Let a Nutrient Deficiency Get You “Down”!

NHANES is the National Health and Nutrition Examination Survey, a program run by the Centers for Disease Control (CDC) to assess health and nutrition status of individuals in the United States. A recent review by Reider et al. analyzed the latest set of NHANES data to get a better idea of nutrient intake. Specifically, they looked at Vitamins A, C, D, E and zinc due to their well-known roles in immune function.

The chart above shows the inadequate intakes are for each nutrient, based on intake from food alone and from food plus dietary supplements. While supplements do help bridge the gap for some, many are still left with inadequate intake of several key nutrients.

Another finding from this review was the discovery that intakes of certain nutrients, such as vitamin C, vitamin D, and zinc, are lower than expected from previous reports. The likelihood of being deficient in one or multiple immune boosting nutrients is quite high and even more of a reason to test your levels of vitamin D and zinc to make sure your diet and supplemental intake are helping you achieve adequate levels. These are two of the nutrients tested for in our new Immune Boost test kit.

Nutrients Support Healthy Immune Function

We have previously shared about how Vitamin D is necessary for healthy immune function, especially in response to infection (such as COVID-19), as well as for many other health outcomes. Other nutrients, such as vitamin C and zinc, also work to support the immune response. One study on supplementation with vitamin D, magnesium and vitamin B12 resulted in improved outcomes for individuals with COVID-19. These are just a handful of the nutrients that have an effect on immune system function.

Based on what is known about these nutrients and their roles in immune function, the authors concluded:

“Micronutrients are a fundamental part of the immune system and require optimal levels for effective immune function. Nutrient insufficiency/deficiency of one nutrient can adversely affect immune health, while multiple inadequacies may put the immune system at a bigger deficit.”

Avoid Deficiency – Enroll in the GrassrootsHealth Nutrient Research Immune Boost Project and Test Today

Do you know your own nutrient levels? Do you know your levels of inflammation? Could getting more of certain nutrients help to decrease your levels of inflammation, and improve your immune response? Find out by testing your vitamin D, omega-3s, magnesium and other essential elements (including copper and zinc), as well as your inflammation levels, with the new Immune Boost home test kit offered by GrassrootsHealth. Measuring levels is the only way to know if you are supporting your immune system and whether additional changes should be made, with supplementation, dietary changes, or both.

Enroll now with the Full Immune Boost Panel (which includes tests for vitamin D, Omega-3 Index, magnesium, zinc, selenium, copper, and hsCRP), and get 10% off when you use coupon code BoostTen at checkout.

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, especially COVID-19.

GrassrootsHealth Nutrient Research Institute has launched the new Immune Boost project with the use of our myData-myAnswers nutrient health system that over 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

We hope to 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. Status and intake of other nutrients will also be analyzed for any type of relationship to immune status and symptom severity. 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)
