Vitamin D Effect on Insulin Resistance Localized to Range of 16-36 ng/ml (40-90 nmol/L)
Insulin resistance is when cells in your body don’t respond well, or are resistant to insulin which leads to increased blood sugar and eventually type 2 diabetes. As part of Diabetes Awareness Month this November, we want to bring attention to vitamin D as a diabetes prevention tool. Studies have shown that a higher vitamin D status is associated with both lower insulin resistance and lower risk of type 2 diabetes.
GrassrootsHealth Study on Insulin Resistance and Vitamin D
In 2013, GrassrootsHealth published a study that defined the specific range of vitamin D levels where an effect on insulin resistance was most likely to be found. This analysis used data from 4,116 adult enrollees in Pure North S’Energy Foundation (PNSF), a non-profit Canadian health foundation.
As shown on the chart below, the researchers found that the vitamin D association with insulin resistance was localized to the range of 16-36 ng/ml (40-90 nmol/L). In other words, vitamin D has the biggest impact on insulin resistance for those who start out with levels below 16 ng/ml and raise their levels above 36 ng/ml.
Identifying the response range for a particular disease is important for research and clinical treatment. Many studies use participants who do not start with low enough levels or use a vitamin D dose that is too small to raise levels to the top of the response range, either of which may lead to “no effect” results.
Do you know YOUR vitamin D level?
Could a vitamin D deficiency be affecting your health? Find out today! Using the GrassrootsHealth Custom Kit Builder, you can create a test kit that measures your vitamin D level and other important nutrients (such as omega-3s and magnesium), as well as your CRP level. 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.
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
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!
