Breast Cancer Prevention – the Vitamin D3 Link

Many are aware of the importance of Vitamin D, which is in actuality, a hormone produced by the kidneys to control the concentration of calcium in the blood.  Vitamin D is essential for a strong immune system, support of the skeletal and muscular system, function of the pituitary gland (the master gland which regulates hormone activity), and promotes new cell growth. It is produced through the skin in response to sun exposure, which is the number one suggested form of “getting your Vitamin D” – free is always best!


Vitamin D Deficiency Is Related to 75% Of All Breast Cancers

In September of 2014 The Cure to Cancer Summit provided a very enlightening discussion on the role Vitamin D plays in cancer.  If you are interested in improving your own health, helping a loved one with their battle for cancer, or if you have a health and wellness business (nutrition, medical, oncology, etc) – I highly encourage you to take advantage of the now annual summits, which now go by the summit title of The Truth About Cancer hosted by Ty and Charlene Bollinger.


Carole Baggerly, of the Vitamin D Society, presented her talk, “Vitamin D and Cancer Prevention”. Below I share a summary of the information provided by Baggerly while listening to her interview.


Vitamin D is a hormone, not a vitamin. It is critical for cells to function. People work day jobs that are primarily indoors, children play on computers and watch television more than they play outside….our lifestyles create vitamin D deficiency. If everyone had Vitamin D levels of 40-60 it would help take care of many diseases, such as type 2 diabetes, kidney stones, and several cancers. An oncologist who spoke at the summit last week, who practices in California, said that well over 90% of his patients are deficient in Vitamin D.



  • Breast cancer diagnosis can be reduced 75% if all women were given a Vitamin D 25 Hydroxy test.

  • Blood serum nano-gram levels should be in the 50-60 range. Research is indicating that breast cancer is truly a disease of vitamin D deficiency.

  • 10,000 units a day is being recommended. Don’t fear the toxicity scare – every report of toxicity has been a result of industrial accidents – stop taking D and the levels normalize.

  • Women WITH breast cancer have an increased rate of cancer survival with high doses of Vitamin D. This research has been published in recent months.




  • Colon cancer prevention specifically requires a combination of calcium (10-12,000 mg) and Vitamin D. (Baggerly states that the concern of calcium/vitamin D and kidney stones is a myth, and kidney stones are clearly linked to dehydration).

  • Prostate cancer research by Dr. Bruce Hollis at the Medical University of South Carolina were given 4,000 units/day to men with stage 1 prostate cancer. In a one year period, 55% had fewer lesions than when they started, and allowed them to bypass treatment. This also holds true for African American men, which have a greater percentage of prostate cancer diagnosis.


For men diagnosed with lethal prostate cancer, a 57% reduction of cancer occurred when men got their Vitamin D levels up past 37.




Children should be checked for deficiency as well, they are inside all the time now.Rickets is on an upsurge – we’re going back to the epidemic of the 19th century. Doctors are not recognizing it because we are misled into thinking rickets is not a disease of modern times. Children are spending more times indoors on electronics than they are playing outside in sunshine.


Type 2 Diabetes is an epidemic as well. Research indicates that 60% of Type 2 Diabetes can be prevented if nano-gram levels of Vit. D were maintained at 40%.


Regarding Type 1 Diabetes, in the 1960’s in Finland it was a medical practice to give infants 10,000 units of Vitamin D a day. Type 1 diabetes was virtually non-existent.


Unfortunately, Finland noticed that the U.S. was only supplementing their infants with 400 units of Vitamin D, so Finland switched over to this practice. The diagnosis of Type 1 diabetes increased steadily, and Baggerly states it is the clearest evidence she has seen that indicates Vitamin D can help prevent this childhood disease. Vitamin D is a major game-changer with diabetes.


It is important to realize that there is a problem with Vitamin D deficiency in pregnant women and infant mortality. Not surprising, those who get their vitamin D level to the 40-60 range are reporting the disappearance of chronic pain, muscular pain, and absence of kidney stones,


Baggerly also stated that the recommendations to wear sunscreen has increased our populus vitamin D deficiency and that most sunscreens are toxic and promote cancer. Of course, this is why learning about what is in your skincare products is so important. My family chooses to avoid sunscreen whenever possible – working outside in early morning hours and covering the skin with cotton during the heat of the day. Wide-brimmed hats are recommended to shield the face and neck. Thirty minutes of sunshine per day, without sunscreen,  helps one receive a good dose of Vitamin D as nature intended.

Testing and Supplementation


As you can see, it is very important that physicians begin testing everyone for Vitamin D levels. If yours does not, I urge you to be your own advocate and request the alpha-hydroxy Vitamin D test. This should become a standard test for anyone over the age of fifty. To learn more about Vitamin D benefits and testing, please visit the Vitamin D Society. I also encourage anyone wishing to donate to cancer research that makes a difference, to donate to the research of the Vitamin D Society for cancer prevention, and therapy as well. 

It is important to realize there are two types of Vitamin D. Vitamin D2 (ergocalciferol) is derived from plant sources and the body needs to convert it to Vitamin D3. However, these days metabolic and digestive pathways blockages prohibit the conversion process.  Vitamin D3 (cholecalciferol) comes from a limited source of animal proteins, such as beef liver, fatty fish, eggs and cod liver oil. (Please note that eggs are considered in the top nine inflammatory food groups. It is not uncommon for a bio-energetics scan to recognize egg whites, egg yolks, or the whole egg as inflammatory for Purely Living Wellness clients.)


There are different theories on vitamin synergies, which in itself is a topic for an article. Bio-availability is key, and Vitamin K2 is one vitamin experts are saying should be taken along with D3. I always recommend finding a product that contains both vitamins in one supplement, where the ratio has been pre-determined by the scientists who formulate the product. Personally, I take a Vitamin D3 capsule that contains magnesium, zinc, and Vitamin C, as well as additional antioxidants. You can find gel caps, which are easier to swallow, but often do not contain K2 – please be mindful of reading labels.  Capsules, drops, and oral sprays are all now readily available. Many physicians are now realizing the importance of Vitamin D3 and are recommending their patients take 5,000 IUs per day, especially during the months of November through March in areas where cold and snow may keep people indoors.  Living in the Midwest, we recommend that every adult, and often children, supplement with Vitamin D3, as it is an absolute must to help prevent what is known as the “winter blues”.
