- Blacks with prostate cancer were 7 X more likely to have aggressive prostate cancer if they also supplemented with more than 800 mg of Calcium Daily
- Blacks somewhat more likely to have aggressive prostate cancer if all 3 VDR genes were poor
- Blacks with aggressive prostate Cancer were also more likely to have quit smoking

- Smoking reduces vitamin D
probably the reduction of vitamin D levels while still smoking increased the growth of prostate cancer - Death by Calcium, book by Thomas Levy – Dec 2013
- Increased Vitamin K2 reduces the problems of excess Calcium – Nov 2013
Vitamin K2 reduces Calcium getting into wrong locations - like blood vessels and probably Prostate - Is a health problem associated with Low vitamin D, Low Magnesium, or too much Calcium – Jan 2016

Vitamin D Receptor category has the following
Vitamin D tests cannot detect Vitamin D Receptor (VDR) problems
A poor VDR restricts Vitamin D from getting in the cells
It appears that 30% of the population have a poor VDR (40% of the Obese )
A poor VDR increases the risk of 55 health problems click here for details
The risk of 44 diseases at least double with poor Vitamin D Receptor as of Oct 2019
VDR at-home test $29 - results not easily understood in 2016
There are hints that you may have inherited a poor VDR
Compensate for poor VDR by increasing one or more:
| Increasing | Increases |
| 1) Vitamin D supplement Sun, Ultraviolet -B | Vitamin D in the blood and thus in the cells |
| 2) Magnesium | Vitamin D in the blood AND in the cells |
| 3) Omega-3 | Vitamin D in the cells |
| 4) Resveratrol | Vitamin D Receptor |
| 5) Intense exercise | Vitamin D Receptor |
| 6) Get prescription for VDR activator paricalcitol, maxacalcitol? | Vitamin D Receptor |
| 7) Quercetin (flavonoid) | Vitamin D Receptor |
| 8) Zinc is in the VDR | Vitamin D Receptor |
| 9) Boron | Vitamin D Receptor ?, etc |
| 10) Essential oils e.g. ginger, curcumin | Vitamin D Receptor |
| 11) Progesterone | Vitamin D Receptor |
| 12) Infrequent high concentration Vitamin D Increases the concentration gradient | Vitamin D in the cells |
| 13) Sulfroaphone and perhaps sulfur | Vitamin D Receptor |
Note: If you are not feeling enough benefit from Vitamin D, you might try increasing VDR activation. You might feel the benefit within days of adding one or more of the above
Far healthier and stronger at age 72 due to supplements Includes 6 supplements which help the VDR

African American men have higher incidence rates of aggressive prostate cancer, where high levels of calcium and serum vitamin D deficient levels play a role in the racial differences in incidence. In this study, we examined associations of serum vitamin D with aggressive prostate cancer to improve our understanding of higher susceptibility of aggressive disease in this racial cohort. From Howard University Hospital, 155 African American men with clinically-identified prostate cancer were identified; 46 aggressive cases, and 58 non-aggressive cases. Serum vitamin D was assessed from fasting blood samples, and total calcium intake was assessed using the Block Food Frequency Questionnaire.
Vitamin D receptor polymorphisms from three different loci were genotyped;
- rs731236,
- rs1544410, and
- rs11568820.
Multivariate logistic regression models were used to determine odds ratios (OR) and 95% confidence intervals (CI) comparing aggressive to non-aggressive prostate cancer. Vitamin D deficiency (<20 ng/mL) significantly increased risk of aggressive disease (OR: 3.1, 95% CI: 1.03–9.57, p-value = 0.04). Stratification by total calcium showed high calcium levels (=800 mg/day) modified this association (OR: 7.3, 95% CI: 2.15–47.68, p-interaction = 0.03). Genetic variant rs11568820 appeared to increase the magnitude of association between deficient serum vitamin D and aggressive prostate cancer (OR: 3.64, 95% CI: 1.12–11.75, p-value = 0.05). These findings suggest that high incidence of aggressive prostate cancer risk in African
American men may be due in-part to deficient levels of serum vitamin D. Other factors, including genetics, should be considered for future studies.
