IN HONOR OF BREAST CANCER AWARENESS, HAVE YOUR VITAMIN D LEVELS CHECKED

***THESE STATEMENTS HAVE NOT BEEN APPROVED OR REGULATED BY THE FDA.  WE ARE NOT DOCTORS, THEREFORE ALWAYS CONSULT WITH YOUR DOCTOR FIRST.

In honor of breast cancer awareness, Have your vitamin D levels checked.  Vitamin D3 should be taken with vitamin K2 to properly absorb.  Several studies show that higher vitamin D levels are protective against many forms of cancer, particularly breast cancer.  Women with vitamin D levels above 60 ng/mL have a much lower risk of breast cancer than those below 20 ng/mL.

Research has shown that once you reach a minimum serum vitamin D level of 40 nanograms per milliliter (ng/mL), your risk for cancer diminishes by 67 percent, compared to having a level of 20 ng/ml or less.4

Research shows most cancers occur in people with a vitamin D blood level between 10 and 40 ng/mL, and the optimal level for cancer protection has been identified as being between 60 and 80 ng/mL.

Vitamin D also increases your chances of surviving cancer if you do get it,5,6,7,8 and evidence suggests adding vitamin D to the conventional treatment for cancer can boost the effectiveness of the treatment.9

Several studies also show that higher vitamin D levels are protective against breast cancerspecifically. Importantly, a 2005 study10 showed women with vitamin D levels above 60 ng/mL have an 83 percent lower risk of breast cancer than those below 20 ng/mL, and I cannot think of any other strategy that can offer that kind of risk reduction. Mammograms certainly cannot.

More recently, a pooled analysis11 published in June 2018 of two randomized trials and a prospective cohort study came to a near-identical conclusion. The objective was to assess whether there are any benefits to having a vitamin D level above 40 ng/mL, as most studies do not venture into these higher levels.

Indeed, mirroring the 2005 findings, women with vitamin D levels at or above 60 ng/mL had an 82 percent lower incidence rate of breast cancer than those with levels of 20 ng/mL or less.

Pooled data were analyzed in three different ways. First, incidence rates were compared based on vitamin D levels ranging from 20 to 60 ng/mL. Next, statistical analysis using Kaplan-Meier plots were done. Third, multivariate Cox regression was used to examine the association between various vitamin D levels and breast cancer risk. According to the authors:

"Results were similar for the three analyses. First, comparing incidence rates, there was an 82 percent lower incidence rate of breast cancer for women with 25(OH)D concentrations ≥60 vs <20 ng/mL.

Second, Kaplan-Meier curves for concentrations of <20, 20–39, 40–59 and ≥60 ng/mL were significantly different, with the highest proportion breast cancer-free in the ≥60 ng/ml group (99.3 percent) and the lowest proportion breast cancer-free in the <20 ng/ml group (96.8 percent). The proportion with breast cancer was 78 percent lower for ≥60 vs <20 ng/mL.

Third, multivariate Cox regression revealed that women with 25(OH)D concentrations ≥60 ng/ml had an 80 percent lower risk of breast cancer than women with concentrations <20 ng/mL, adjusting for age, BMI, smoking status, calcium supplement intake, and study of origin …

Higher 25(OH)D concentrations were associated with a dose-response decrease in breast cancer risk with concentrations ≥60 ng/mL being most protective."
