While it is true that the majority of individuals have no issues when taking vitamin D (in fact, many notice improvements in how they feel), there is a very small percentage of people who do experience unwanted side-effects. Yesterday, we discussed the condition of primary hyperparathyroidism, which is often asymptomatic however, supplementing with vitamin D has the possibility of “unmasking” the condition and its symptoms.

We will continue with our vitamin D myth busting series after discussing these rare but very real situations in which individuals with certain conditions may experience what seems to be a hypersensitivity to vitamin D supplementation, and sometimes, to the sun as well.

Sarcoidosis and Other Granulomatous Disorders

Granulomatous disorders, which include sarcoidosis, tuberculosis, lymphomas, leprosy, fungal diseases, infantile subcutaneous fat necrosis, giant cell polymyositis, and berylliosis, are rare disorders that may lead to vitamin D hypersensitivity. These disorders involve granulomas, or abnormal masses of inflamed tissue or immune cells, that have the potential of changing the structure and function of certain organs. In sarcoidosis, the lungs and lymph tissues are most commonly affected, and symptoms may include sudden onset of weight loss, fever, fatigue, shortness of breath, and certain skin conditions.

Why can individuals with these diseases develop vitamin D hypersensitivity?

Individuals with these diseases can be known to have issues with calcium metabolism resulting in hypercalcemia. In some, hypercalcemia and other symptoms of vitamin D toxicity can be induced with very little intake of vitamin D or exposure to UVB, with symptoms that may even be “summer induced” or associated with seasons of higher UVB exposure. Individuals with these diseases tend to have low or normal levels of 25(OH)D, whereas vitamin D toxicity is usually associated with high 25(OH)D levels, above 200 ng/ml. This imbalance is due to the uncontrolled conversion of 25(OH) vitamin D (the form of vitamin D most often measured in the blood) to 1,25(OH)2D (the hormonal form of vitamin D) within the granulomatous tissues. The 1,25 vitamin D then becomes abnormally high and over-acts on the intestines and bone to pull calcium into the blood, which then can lead to symptoms of vitamin D toxicity and hypercalcemia, including bone softening, kidney stones and other renal problems.

It is important to note that this dysfunction of vitamin D induced hypercalcemia is not common among all granulomatous disorder patients – in fact, sun therapy has a history of providing healing benefits to those with tuberculosis, and higher 25(OH)D levels have been associated with an increased survival rate in lymphoma.

If you know or suspect that you have any of these conditions, or if you experience what feels like a hypersensitivity or negative effects due to vitamin D, please work with your health care provider to address these conditions, and work with them to safely resolve any existing vitamin D deficiency.

Is it true?

Our “Vitamin D Myths” series will continue to provide information and resources to answer the question, “Why should I care about vitamin D?” and to help dispel the myths and misconceptions surrounding it that may be preventing you and others from accepting it as an essential component to health. We will also discuss other nutrients essential to the function of vitamin D (and vice versa) within the body that should not be ignored.

Vitamin D is necessary for multiple functions within the body and should not be ignored, but has the hype about vitamin D and its role in the body’s response to COVID-19 been over-exaggerated? What concerns about vitamin D are valid, and which are not? We want to provide you with evidence based information to help you decide what vitamin D action to take, if any, for your own health.

We want to hear from you!

Is there a particular ‘myth’ you have heard about vitamin D? Or, something you have read or been told that makes you question whether vitamin D ‘deserves’ so much attention? Or whether you should be taking it and how much? Share with us by emailing jen @grassrootshealth.org what you have heard that makes you question vitamin D so that we can consider addressing it in our newsletters.

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.

GrassrootsHealth Nutrient Research Institute is preparing to do a Community RCT with the use of our myData-myAnswers nutrient health system that over 15,000 people are already using for their health. We will 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. Please let us know if you’re interested in helping sponsor this project.

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!

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.

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.

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!
