Video Friday: To kick off Breast Cancer PREVENTION Month, we share this video by our director, Carole Baggerly, about her breast cancer story turned inspiration

Key Points

  • An estimated 67-70% of breast cancer could be prevented by achieving a vitamin D level of at least 40-60 ng/ml; in fact, women with vitamin D levels at or above 60 ng/ml (150 nmol/L) had an 80% lower breast cancer risk compared to women with levels less than 20 ng/ml (50 nmol/L)
  • GrassrootsHealth and D*action were started after director Carole Baggerly’s experience with breast cancer and its treatment – watch the video to hear her story!
  • D*action is about more than just testing vitamin D levels; it is about participating to improve vitamin D levels for ALL through measurement, education, action, research, and most importantly, spreading the word!

“By following the recommendations made by our scientists panel, it is estimated that we could have an annual 67-70% reduction in incidence of breast cancer, as well as type 1 diabetes, multiple sclerosis, colon cancer… within only 5 years!”

October is Breast Cancer Awareness Month, which we would rather refer to as Breast Cancer PREVENTION Month. Throughout the month we will be presenting information on vitamin D and other nutrients that have been linked to a reduction in breast cancer incidence and recurrence – since, after all, the best medicine is safe, effective PREVENTION!

To kick off the month, please tune in to the video below, which features our Director, Carole Baggerly, and our Principle Investigator, Dr. Cedric Garland. This video will be featured as Part 1 (with Carole) and Part 2 (with Dr. Garland), but feel free to watch it all at once!

Vitamin D Can Help Prevent Breast Cancer – Is It True? (Part 1)


Carole’s Breast Cancer Turned D*action Story: The motivation behind the beginning of D*action

For anyone who has cancer, has had cancer, or knows anyone who has or had cancer – please share this story and information.

Carole Baggerly was diagnosed with breast cancer in 2005. As she describes it, the cancer was bad enough, but then, she had the treatment for cancer. She had a mastectomy, chemotherapy (which permanently damaged some of her body), and radiation (until she bled), and all of that led her to an intense desire to find a better way to address breast cancer.

Through her research and the research of the scientists she met in the months that followed, she found a way to address it – through prevention.

Carole was invited to attend a two day seminar in May of 2007, sponsored by the National Cancer Institute, with researchers from all over the world presenting what they knew about vitamin D and cancer. So much was already known about vitamin D and cancer! Yet what were they going to do with the information? What was the researchers’ response to how they were going to get the message out?

Carole immediately realized that, while these researchers had spectacular scientific knowledge about the role of vitamin D in cancer prevention, their message would fail to get out without a dedicated “sales” team!

She then spent the next three months travelling the United States and Canada to visit vitamin D researchers with the goal of creating a defined message about vitamin D. Unfortunately, the question that is often asked, “What dose should I take?” was the wrong question to be answering and would therefore lead to the wrong message… since someone’s dose depends on several different factors and varies widely from person to person.

Based on a consensus from a panel of now 48 respected vitamin D scientists from around the world, the key message about vitamin D remains the same as it was first defined at the start of D*action – the 25(OH) vitamin D level in the blood should be 40-60 ng/ml (100-150 nmol/L), and given that, the correct dose can be determined.

With this as the core message, D*action was born to help get the message out, to give access to many individuals who did not have a way to test their vitamin D level at the time, and to further define the health outcomes related to a level within the 40-60 ng/ml range.

Key Points to Get Across with the D*action Project

  • what is the “natural” vitamin D level – where does the 40-60 ng/ml (100-150 nmol/L) come from?
  • levels below 40-60 ng/ml are not adequate or “normal”
  • people in the northern latitudes taking 4000 IU per day only reached an average level of 32-34 ng/ml (80-85 nmol/L) – many still need more! But how do you know if you do need more? Measure your level, which you can do through D*action.
  • the Disease Incidence Prevention Chart shows a list of diseases that could be reduced upon reaching target levels of vitamin D. For example, one study showed a 35% reduction in all cancers upon reaching a vitamin D level of 38 ng/ml (95 nmol/L)… newer studies show an even greater reduction with vitamin D levels above 60 ng/mlthis is primary prevention!
  • concerned about toxicity? Read this
  • “We would have a changed country” if everyone got their vitamin D levels up… discover more of the research showing the benefits of vitamin D and other nutrients for different diseases and health outcomes on the GrassrootsHealth blog

Something Non-Toxic and Inexpensive Can Really, Truly Help Prevent Cancer!

LOTS of studies show the same thing… it is clear that the issue with breast cancer is directly related to vitamin D

Continue watching the video to learn about vitamin D from Dr. Cedric Garland, and hear about the initial findings from the D*action study, or wait for the summary in Part 2 coming soon!

What is D*action?

D*action started out as a 5 year (now on-going) public health project to provide education and research to SOLVE the vitamin D deficiency epidemic, by measuring vitamin D serum levels, collecting health data from participants, and tracking the health effects of getting to levels of 40-60 ng/ml (100-150 nmol/L).

Take action now! We know enough to reduce diseases today.

  1. Measure your vitamin D level (sign up and participate in the study)
  2. Adjust your level (through supplementation, co-nutrients, sun, food)
  3. Re-test to see if you’ve achieved your target
  4. Spread the word to everyone you know!

Learn more about what is involved in participation, additional discoveries that have been made using participant data and results, other top areas of interest in further data analysis and findings, and new standards of care that have been implemented into medical practice due to what we already know about vitamin D!

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.
