Reducing Breast Cancer Risks and Improving Patient Survival – A Summary of Research on Vitamin D, Other Nutrients & Lifestyle Habits

According to breastcancer.org, statistics for breast cancer in the United States indicate the following:

  • 1 in 8 women (about 13%) will develop invasive breast cancer
  • An estimated 281,550 new cases of invasive breast cancer and 49,290 cases of non-invasive breast cancer are expected to be diagnosed in the year 2021
  • An estimated 2650 cases of new invasive breast cancer is expected to be diagnosed in men in 2021
  • An estimated 43,600 women are expected to die from breast cancer in 2021

While the overall death rate from breast cancer between 2013 and 2018 decreased by about 1% each year, most of the decrease has been in women over 50 years of age, with rates holding steady in women under 50. Women who are Black are more likely to die of breast cancer, and a diagnosis before the age of 45 is more common among Black women than White women.

Vitamin D Status Can Help Predict Breast Cancer Risk and Disease Survival

Research has repeatedly shown that women with higher vitamin D levels have up to an 80% decreased risk of getting breast cancer compared to women with lower levels, and breast cancer patients with higher levels of vitamin D are up to twice as likely to survive the disease as women with lower levels. This is JUST with vitamin D!

Unfortunately, almost 90% of U.S. adults have a vitamin D level below the recommended range of 40-60 ng/ml (100-150 nmol/L), with approximately 23% below 20 ng/ml (50 nmol/L).  Blacks overall have a 15-20 fold higher prevalence of severe vitamin D deficiency, which may account for a majority of their increased health and mortality risks, including those with breast cancer.

Summary of Breast Cancer Research… Take action and share the research today!

For any person who is concerned with maintaining good health, it is important to understand the life-saving link between vitamin D and being healthy. Taking the necessary steps to avoid or correct a deficiency and maintain a target vitamin D level is absolutely essential. Vitamin D intake and levels can heavily influence how many diseases progress, the chances of survival, and even getting the disease in the first place – especially in the case of breast cancer.

To make it easier to share how vitamin D and other nutrients and lifestyle habits affect breast cancer risk and outcomes, we have compiled a webpage with a summary of all of our previous research-based posts with the following outline:

Measure Your Status of Vitamin D and Other Nutrients

There is overwhelming evidence showing a significant relationship between higher vitamin D levels and a lower risk of getting breast cancer, as well as a lower risk of death among breast cancer patients.  Other nutrients and lifestyle habits, especially those that contribute to decreasing inflammation, are also important for improving breast cancer outcomes.

Having and maintaining healthy levels of vitamin D and other nutrients can help improve your health now and for your future. Choose which to measure, such as your vitamin D, selenium with other 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.

Help everyone Move Research into Practice with vitamin D and other nutrients! As a special birthday gift to everyone, in honor of the science, we have created a special scholarship fund for anyone to donate to that will go towards helping others participate. Your donation will allow anyone to get help with funding their participation when they need 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.


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!
