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 )
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:
|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|
|Vitamin D Receptor|
|7) Quercetin (flavonoid)||Vitamin D Receptor|
|8) Zinc is in the VDR||Vitamin D Receptor|
|9) Boron||Vitamin D Receptor ?, |
|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) Sulfroaphane 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 that help the VDR

Vitamin D is involved in a wide variety of biological processes including bone metabolism, modulation of the immune response, and regulation of cell proliferation and differentiation. The present study aimed to investigate vitamin D status and the genetic polymorphism BsmI (A/G) of vitamin D receptor (VDR) among a group of Egyptian female patients with breast cancer.
The current study included 60 female patients diagnosed as breast cancer (BC) attending Mansoura Oncology Center, Mansoura University, and 60 age-matched healthy control females. Serum 25(OH) vitamin D level was measured using Enzyme-linked immunosorbent assay (ELISA) kit. A polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) method and fragment analysis were performed to determine the VDR BsmI (A/G) polymorphism.
25(OH) vitamin D levels were significantly lower in the patients with BC (22.1 ± 10.9 ng/ml) compared to controls (41.2 ± 11.22 ng/ml) (p 0.001). Vitamin D deficiency- insufficiency was reported in 76.7% of BC patients and 20% of the controls (P 0.001, OR = 13.1, 95%CI = 5.5 - 31.4).
Bb genotype was statistically higher in the BC patients than in the healthy controls (P 0.001).
- 81.2% of BC patients were of Bb genotype,
- 10.9% of BB genotype and
- 4.3% of bb genotype,
while in controls, 33.3% for each genotype.
No statistically significant difference in allele frequency was observed between the two studied groups.
Carriers of Bb genotype had 4.6 times increased risk of developing breast cancer (95% confidence interval of 2.0–10.3) when compared to other genotypes.
A significant association exists between vitamin D deficiency and the risk of breast cancer. B allele or Bb genotype of VDR may be a susceptibility risk factor for BC development.
