This updated illustration shows why it is important to ensure vitamin D levels are 40-60 ng/ml (100-150 nmol/L) for a healthy pregnancy and baby
Numerous studies have found that higher vitamin D levels among pregnant women reduce the risk of adverse maternal and infant outcomes. We reviewed and compiled many of these findings to create an updated version of the Pregnancy Disease Risk Reduction Chart below.
The Pregnancy Disease Risk Reduction Chart shows the percent lower risk at a given vitamin D level compared to a common reference level of 25 ng/ml (62 nmol/L), which is the approximate average level of the U.S. population. For example, preterm birth risk is reduced by 35% when the serum level is 40 ng/ml (100 nmol/L) compared to the reference level of 25 ng/ml.
Ensuring a vitamin D level in the range of 40-60 ng/ml (100-150 nmol/L) during pregnancy is an effective way to reduce the risk of complications. Do you know your vitamin D level? Take action now to reach your target vitamin D level; start by finding out where your level is at today.
How was this chart created?
There are many studies that have been published concerning the role of vitamin D in maternal and infant outcomes – some of which report conflicting results. You may ask how we chose the studies we did.
We began by reviewing whether there was a known mechanism for how vitamin D would play a role in each outcome. We then reviewed meta-analyses published in the previous two years because they included the most recent data available. Meta-analyses combine the results of observational studies and/or randomized control trials to determine an overall effect of vitamin D on their outcome of interest. Several meta-analyses have found that vitamin D deficiency is associated with the development of many adverse pregnancy-related conditions and infant outcomes, and that vitamin D supplementation improves those outcomes.
To select studies for the Pregnancy Disease Risk Reduction Chart, we reviewed the trials included in the meta-analyses and studies published after the meta-analyses were reported to identify studies that reported data we could use. The study needed to report statistically significant disease risk reduction in relation to vitamin D levels, more specifically serum 25(OH)D levels. Also, the analysis needed to include vitamin D levels above the reference level of 25 ng/ml (62 nmol/L). Of the identified studies, those selected for the chart had the highest levels of evidence (RCT, longitudinal, then case-control), included participants with the broadest range of vitamin D levels, and had the largest study populations.

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.
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.
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
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!
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
