Do vitamin D levels in children affect their chance of getting COVID-19 and its severity?

While children do not tend to be as severely affected by the SARS-CoV-2 virus and the resulting effects of COVID-19, they are certainly not immune to it, and there is concern that children who carry the virus but are asymptomatic are a contributor to its spread.

Children are also not ‘immune’ to vitamin D deficiency – in fact, a previous post shared data from the US NHANES data set showing that vitamin D levels decline as children age, with a 4-fold increase in the proportion of children below 20 ng/ml (50 nmol/L) from ages 0-4 years up to ages 13-17 years old.

How Might Vitamin D Levels in Children Affect Their COVID-19 Status?

To answer this question, Kamil Yilmaz and Velat Sen conducted a study in which they enrolled 85 children between the ages of 1 month to 18 years, 40 of whom had been diagnosed with COVID-19 and hospitalized, and 45 who were healthy controls. Children with chronic diseases and other co-morbidities were excluded from the study.

Children diagnosed with COVID-19 were divided into two groups for analysis – Group 1 included children who had a vitamin D level below 20 ng/ml, and Group 2 included those with levels at or above 20 ng/ml.

What did the study find?

The study found a significant difference in vitamin D levels between the children with COVID-19, who had a median level of 13 ng/ml (32 nmol/L), and the control group, with a median level of 35 ng/ml (87 nmol/L).

When disease severity for the children who were diagnosed with COVID-19 was analyzed according to vitamin D level, a trend was found showing increased disease severity for those with lower vitamin D levels. In fact, among those with a vitamin D level below 20 ng/ml (50 nmol/L), 31% of the children had moderate to severe COVID-19 symptoms, compared to only 18% with moderate symptoms (none classified as severe) for those children with vitamin D levels of 20 ng/ml or higher. Additionally, 46% of the children with higher vitamin D levels were asymptomatic, compared to 10% of those with lower vitamin D levels.

The study also found a significant negative correlation between vitamin D level and the chance of getting a fever (defined as a temperature above 100.4 F or 38 C, p=0.023), meaning that as vitamin D levels increased, the chance of fever decreased. Overall, none of the children with a vitamin D level of at least 20 ng/ml had a fever, while 34.5% of those with levels below 20 ng/ml did.

Ensure Vitamin D Levels of 40-60 ng/ml (100-150 nmol/L) for You, Your Children, Loved Ones

Remember, it is just as important for your children to avoid vitamin D deficiency as it is for you! Ensure your children are also getting enough vitamin D for a strong, healthy immune response. Correcting a vitamin D deficiency at any age and any time of life decrease potential disease severity and improve outcomes! Test your vitamin D level today, learn what steps to take to improve your level, and take action to achieve and maintain a vitamin D level of 40-60 ng/ml (100-150 nmol/L).

Using the GrassrootsHealth Custom Kit Builder, you can create a test kit that measures your status of vitamin D and other important nutrients (such as omega-3s, zinc and magnesium), as well as your CRP level to measure inflammation. Click here to build and order your test kit today – measure your status and take the steps necessary to improve them if needed; make an impact on your health today and for your future! When you know what your levels are, you can determine next steps to take and how much supplementation may be needed if you are not at your target levels.

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!
