The COVID-19 pandemic continues to demand greater attention for vitamin D NOW! Help get this vital information out to everyone today.

Key Points

  • Help create and sustain the sense of urgency to take vitamin D*action for COVID by educating, knowing your vitamin D level, and taking steps to reach a target level of at least 40 or 50 ng/ml (100 or 125 nmol/L)
  • Giving Tuesday is tomorrow!  Please consider donating to GrassrootsHealth.

We Can’t Wait! while the COVID-19 pandemic continues to claim lives. The research has consistently shown that vitamin D status correlates with length of ongoing COVID disease, severity of symptoms, and mortality risk. There is much evidence that low vitamin D is a predictor of infection and death, and that “a fatal outcome from COVID-19 infection, apart from other risk factors, is strongly dependent on the vitamin D status of the patient.”

Help Create and Sustain the Sense of Urgency to Take Action!

Action #1 – Know & Share the Research

Vitamin D & COVID-19 Research

There are now dozens of published studies showing the effects of vitamin D on COVID-19 outcomes, and hundreds more supporting its role in immune function. A summary of some of that research can be found here, along with research on other nutrients and immune health – please share it with others! (Would you prefer a PDF download of this research summary to share? Let us know by emailing jen @grassrootshealth.org, and with enough interest, we will create one for all!)

One meta-analysis in particular, by Petrelli et al., included 43 studies with data from a total of 612,601 COVID-19 patients, and found that

  • Risk of COVID-19 infection was 50% higher among those whose vitamin D levels were below 20 ng/ml
  • Risk of severe COVID-19, defined as the need for intensive care and/or mechanical ventilation, was 160% higher among those with vitamin D levels below 20 ng/ml
  • Risk of death due to COVID-19 was 22% higher among those with vitamin D levels below 20 ng/ml
  • Vitamin D supplementation of various doses reduced the risk of severe COVID-19 disease by 73% and death by 59%

Another review by Borsche et al. confirmed an inverse correlation between COVID-19 mortality and vitamin D levels, demonstrating that as vitamin D levels increase, COVID-19 mortality decreases, to a point where the projected mortality rate reaches zero at around 50 ng/ml (125 nmol/L).

A paper by Kaufman et al. looked at lab data from over 190,000 patients from 50 states and found that the percent of positive SARS-CoV-2 tests was 12.5% for those with vitamin D levels less than 20 ng/ml (50 nmol/L) and 5.9% for those with levels at or above 55 ng/ml (138 nmol/L), which is a 53% lower positivity rate with higher vitamin D levels!

What is your vitamin D level? The levels of your family? Your friends? Do you and those you love have a level of at least 40 ng/ml (100 nmol/L)? Or would you prefer to have a level closer to 50 or 55 ng/ml as suggested by the research mentioned above?

Action #2 – Know Your Vitamin D Level & Take Action to Achieve Your Target

Order Tests & Enroll

Take the steps below to ensure a vitamin D level of at least 40-60 ng/ml (100-150 nmol/L). Make sure everyone you know understands these steps and is acting on them. You, your family, and your community can be the start of putting an end to the negative health consequences of vitamin D deficiency!

Remember… Supplementation does not always provide the expected change in vitamin D level. It is vital to TEST, ADJUST, RE-TEST and REPEAT to make sure that the daily dose or vitamin D routine is effective at achieving and maintaining the desired target vitamin D level. For example, an analysis of 5,442 GrassrootsHealth participants who completed at least two vitamin D tests showed that two-thirds (67%) reached a vitamin D level of at least 40 ng/ml on their second test – leaving 1/3 of those who re-tested still below the 40 ng/ml target level.

Enroll in the project and follow the steps below to ensure you achieve your target vitamin D level.

Action #3 – Donate to GrassrootsHealth (HINT: Tomorrow is Giving Tuesday!)

Grant funding for nutrients, such as vitamin D, is rare. The money is not in nutrients, but drugs.

Your donation today will help continue to expand GrassrootsHealth’s reach – to spread the word about the benefits of vitamin D within recommended ranges of 40-60 ng/ml (100-150 nmol/L) to individuals, health care providers, public health officials, and all.

We thank you for your donations!

What Does it Take YOU to Get Your D to 40 ng/ml (100 nmol/L)? To 50 ng/ml (125 nmol/L)?

Everyone responds differently to vitamin D; the same dose of vitamin D is likely to result in different vitamin D levels from one person to the next, by up to 6 times! There are certain steps that are essential to ensuring you have found the right dose of vitamin D and/or the right vitamin D routine (using sunshine, UVB, food, or other sources) for the level you are trying to achieve.

STEP 1 – Do you know what your vitamin D level is? Enroll and order your test to find your current vitamin D level

STEP 2 – Complete your online questionnaire as part of being a Citizen Scientist in the Vitamin D*action project

STEP 3 – 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), however, some research indicates levels over 60 ng/ml may be beneficial for certain conditions such as autoimmune diseases and cancer.

STEP 4 – 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 5 – Implement your new supplement dose and/or routine (will you include sunshine or an indoor UVB device, increase vitamin D rich foods, etc.?), and optimize how your body absorbs and utilizes vitamin D with co-nutrients and these simple steps.

STEP 6 – Re-Test! This step is VITAL to make sure you have reached your target level, and to ensure you are not taking too much! Re-testing after 3-6 months is recommended or sooner if using a loading dose. Adjust your intake and/or routine again if needed, or consider evaluating vitamin D co-nutrients or other factors if you did not achieve the result you expected.

STEP 7 – Repeat, adjust, repeat, until you have reached your target! Experts suggest testing a minimum of twice each year to make sure target levels are maintained, as levels tend to be highest at the end of summer and lowest at the end of winter.

Don’t get stuck with low vitamin D levels – learn more about what might affect your level and response to supplementation, and the steps to take through each season to keep levels in your target range.

NEWS ALERT

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!
