A review of the strongest evidence available identifies differing optimal vitamin D levels needed to help prevent diseases known as major causes of death

Key Points

  • A new review by Grant et al. has defined optimal vitamin D levels necessary to help prevent certain diseases known to be major causes of death, based on a review of the strongest evidence published to date
  • Optimal vitamin D levels needed for each outcome ranged from 25 ng/ml to 60 ng/ml – all of which were above the 20 ng/ml vitamin level recommended by the Institute of Medicine
  • Each system within the body has its own requirement for vitamin D in order to function optimally – measuring the vitamin D level is the only way to tell if you are getting enough vitamin D for your specific health concerns

Dr. William Grant is a GrassrootsHealth scientist panel member who has published many papers on vitamin D which been cited over 20,000 times, according to Scholar.Google.com.  He is listed as a top author for both Vitamin D and Vitamin D Deficiency, and has received the “World Expert” title for sunlight.

A new review by Grant et al. has defined optimal vitamin D levels necessary to help prevent certain diseases known to be major causes of death, based on a review of the strongest evidence published to date. Diseases identified as those with the highest mortality rates included cardiovascular disease, hypertension, cancer, type 2 diabetes, Alzheimer’s Disease, and COVID-19.

Vitamin D Levels Required to Achieve Various Health Results

The findings, which are illustrated in the graph below, showed that optimal vitamin D levels needed for each outcome ranged from 25 ng/ml to 60 ng/ml – all of which were above the 20 ng/ml vitamin level recommended by the Institute of Medicine.

As the authors state, based on the evidence, “…given the multiple indications of significant health benefits from raising serum 25(OH)D concentrations above 30 or 40 ng/mL as well as the near absence of adverse effects, significant improvements in health at the individual and population levels could be achieved.”  These results could be seen simply through achieving and maintaining optimal vitamin D levels!

Different Requirements for Different Systems and Outcomes

The significance of vitamin D on disease prognosis has been demonstrated by thousands of studies, on many different diseases or conditions, including breast cancer, prostate cancer and other cancers, thyroid disease, diabetes, and others. Each system within the body has its own requirement for vitamin D in order to function optimally. For example, while bone health may be optimized with a vitamin D level of at least 20 ng/ml, immune health may not be optimized until a vitamin D level of at least 50 ng/ml has been achieved, and the greatest reduction in breast cancer risk may not be seen until a vitamin D level of at least 60 ng/ml has been reached.

The Disease Incidence Prevention (DIP) Chart was one of the first graphics created by GrassrootsHealth, and it remains the most popular. It displays the reduction in risk of several diseases based on varying vitamin D levels. The DIP chart along with the Grant et al. study are reminders that

“…raising serum 25(OH)D concentrations to optimal concentrations will result in a significant reduction in preventable illness and death.”

Measuring vitamin D status and supplementing to reach optimal levels is a safe, simple, and effective way to improve health and help prevent disease – start by finding out your level today!

Are You Getting Enough Vitamin D for Your Health Concerns?

Having and maintaining healthy vitamin D levels and other nutrient levels can help improve your health now and for your future. Choose which additional nutrients to measure, such as your omega-3s and essential minerals including magnesium and zinc, by creating your custom home test kit today. Take steps to improve the status of each of these measurements to benefit your overall health. You can also track your own intakes, symptoms and results to see what works best for YOU.

Enroll and test your levels today, learn what steps to take to improve your status of vitamin D (see below) and other nutrients and blood markers, and take action! By enrolling in the GrassrootsHealth projects, you are not only contributing valuable information to everyone, you are also gaining knowledge about how you could improve your own health through measuring and tracking your nutrient status, and educating yourself on how to improve it.

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!

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!
