Vitamin D3

D3 is a hormone needed for immune function. All breast cancer patients should be tested for vitamin D deficiency and supplement with vitamin D3 as needed.  Breast cancer risk was found to be 45 percent lower in women with high vitamin D blood concentrations. Vitamin D acts as a cancer-protective agent by exerting anti-proliferative effects on cancerous cells.

Vitamin D affects breast cancer to a degree that it is being described as a “vitamin D deficiency syndrome.” Researchers have discovered that those with the lowest vitamin D levels are at the highest risk while those with the highest vitamin D levels have the highest survival rate and the least reoccurrence, and studies have shown a 66 percent less risk of metastasis with normal D level.

Once your vitamin D is up to a normal level, daily exposure to sunshine may be enough to support your liver’s ability to produce vitamin D.

Vitamin D affects the structure of cells involved in breast cancer. It holds certain breast cells together with a glue-like substance called E-cadherin, which provides structure to the cell. E-cadherin is made up of mostly vitamin D and calcium. Replenishing vitamin D supports breast cell structure and improves immune function, which can substantially reduce breast cancer cell growth.

Recent studies suggest adults need about 8,000 IUs of vitamin D3 per day in order to get serum levels above 40 ng/ml*. A blood test is necessary to determine your circulating blood levels. Be sure to request that your medical provider perform this test if you have not had a Vitamin D test within the last year.

Blood levels: *Goal 50 to 100 ng/ml.

Recommendation: 2000-5000 IU vitamin D3 daily
