Vitamin D plays an essential role during pregnancy, for both the health of the mother as well as the health of the developing baby, during and after pregnancy. In fact, pregnancy is the only time during the life cycle that vitamin D metabolism is not directly related to calcium. The conversion of vitamin D into its active form reaches over three times the normal amount by birth, with calcium levels remaining normal. There is something special about vitamin D during pregnancy!

Why is Vitamin D So Important For Pregnancy and the Baby?

For several years, GrassrootsHealth has emphasized the importance of vitamin D for pregnancy and the newborn, especially with the Protect Our Children NOW! project and its implementation at the Medical University of South Carolina. This project confirmed previous research findings that pregnant women with serum vitamin D levels of at least 40 ng/ml had a 60% lower risk of preterm birth.

The benefits of vitamin D go well beyond pregnancy, however. Vitamin D deficiency in newborns presents an increased risk for impairment in immune function, brain development, and skeletal development, among other things. Health conditions that have been associated with prenatal vitamin D deficiency include asthma, ear and lung infections, autism, type 1 diabetes and other autoimmune conditions, and an increased risk for certain cancers and cardiovascular disease later in life. See our Disease Incidence Prevention Chart for Pregnancy and Children for more details and resources.

What Factors May Affect a Newborn’s Vitamin D Status?

Neonatal vitamin D deficiency typically stems from a mother deficient in vitamin D due to lack of sun exposure, supplementation, and dietary vitamin D during pregnancy.

In a recent cohort study by Karras et al., maternal and neonatal vitamin D statuses were measured at birth and independent risk factors were assessed for maternal vitamin D status.

The research team measured the vitamin D status of 129 mother-newborn pairs postnatally and categorized the pairs into groups based on the baby’s vitamin D level at birth. They found that mothers who gave birth to babies whose vitamin D level was less than 12 ng/ml (< 30 nmol/l) or between 12 and 20 ng/ml (30-50 nmol/l) at birth had lower vitamin D levels than those who gave birth to babies whose vitamin D was greater than 20 ng/ml (> 50 nmol/l). This association is consistent with previous findings showing a direct relationship between the vitamin D level of the mother and that of the baby.

Risk for newborns having a vitamin D level below 12 ng/ml was 7.62-times higher in those born to mothers with vitamin D levels less than 20 ng/ml compared to mothers with levels of 20 ng/ml or higher, after adjusting for alcohol consumption and UVB exposure.

One additional risk factor for newborns to have a vitamin D level below 12 ng/ml in this study was maternal alcohol intake during pregnancy. Babies born to mothers who drank at least 1 alcoholic beverage per week had a 6.18-times higher risk for neonatal vitamin D deficiency at birth, after adjusting for maternal vitamin D status and UVB exposure.

In conclusion, this study supports previous research showing a link between maternal vitamin D level and newborn vitamin D level, with an added risk of alcohol intake during pregnancy.

Help ensure a healthy vitamin D level for baby by testing during pregnancy

Make sure you know your vitamin D level, and take steps to keep it within a target of 40-60 ng/ml or 100-150 nmol/L! 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 an online tracking system called myData-myAnswers. 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!

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!
