Inflammation has been linked to gestational diabetes, a pregnancy condition that affects 5% of pregnancies worldwide. Gestational diabetes causes high blood sugar and can lead to fetal and maternal complications.

The effects of vitamin D and omega-3, which have anti-inflammatory properties, on inflammation, oxidative stress, and pregnancy outcomes among 120 gestational diabetes patients were investigated in a clinical trial and results were published in 2017. Patients were randomly assigned to one of four groups: 1) 2000 mg/day of omega-3 (containing 600 mg of EPA+DHA), 2) 50,000 IU of vitamin D every 2 weeks, 3) both omega-3 and vitamin D, or 4) placebo for both for 6 weeks.

What were the findings of the study?

While patients who received either vitamin D or omega-3 had decreased levels of hs-CRP, a biomarker of inflammation, those who received both vitamin D and omega 3 had the greatest decrease of all treatment groups (P=0.008).

Patients in the vitamin D and omega-3 co-supplementation group also had significantly reduced malondialdehyde levels (P<0.001), a measure of oxidative stress, increased antioxidant capacity (P=0.001), and increased glutathione levels (P=0.001), a measure of antioxidant effect. Additionally, infants born to those in the co-supplementation group had lower rates of hyperbilirubinemiain (a build-up of bilirubin in the body which can lead to jaundice) and hospitalization (P=0.037 for both).

Do you know your levels of vitamin D, omega-3 and hsCRP?

Be sure to know if you are getting enough vitamin D and omega-3s by testing your levels! Daily steps such as increasing sun or vitamin D supplements may be necessary to maintain a level between 40-60 ng/ml (100-150 nmol/L), and increasing omega-3s in the diet or through supplementing may be necessary to keep your Omega-3 Index at a level of at least 8% and AA:EPA ratio at or below 3. Both tests are included with the hsCRP and HbA1c in the Inflammation Panel test kit. Find out your levels today!

Make sure you track your results before and after, about every 6 months!

How can I track my nutrient levels and intake?

To help you track your supplement use, dietary nutrient intake, 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. You can also track your nutrient intake from dietary sources. 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.

Donations made through GiveLively are received in full by GrassrootsHealth.

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.

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!

Please let us know if you're interested in helping sponsor this project.
