From Cerebral Small Vessel Disease: What to Know & What to Do 2018?
It appears that cerebral small vessel disease can increase
- White portions of MRI (poor blood flow) aka White matter hyperintensities
- Note: Multiple Sclerosis shows up as increased white matter on MRIs
- Cognitive decline
- Problems with walking or balance
- Strokes
- Vascular dementia.
Note: Poor Vitamin D Receptors result in less Vitamin D getting to cells,
but DOES NOT reduce the Vitamin D levels in the blood

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 )
Several diseases protect themselves by deactivating the Vitamin D receptor. Example: Breast Cancer
- - - - - - - -
The Vitamin D Receptor is associated with many health problems
Some health problems, such as Breast Cancer, Diabetes, and COVID protect themselves by reducing VDR activation
55 health problems associated with poor VDR
A poor VDR is associated with the risk of 55 health problems click here for details
The risk of 48 diseases at least double with poor VDR as of Jan 2023 click here for details
Some health problem, such as Breast Cancer reduce the VDR
VDR at-home test $29 - results not easily understood in 2016
There are hints that you may have inherited a poor VDR
How to increase VDR activation
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 Receptor |
| 13) Sulfroaphane and perhaps sulfur | Vitamin D Receptor |
| 14) Butyrate especially gut | Vitamin D Receptor |
| 15) Berberine | 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
Highlights
- Vitamin D acting through VDR plays a crucial role in vascular health.
- VDR FokI “f” allele increases risk of cerebral SVD by 1.5-fold in men.
- Serum vitamin D is significantly lower in subjects with FokI “ff” genotype.
- FokI “ff” increases risk of SVD by 2.5-fold in subjects with low serum vitamin D
- ApaI polymorphism confers protection against SVD in women.
Vitamin D receptor (VDR) and its ligand Vitamin D, play a crucial role in regulating multiple pathways for maintaining vascular health. The present study aimed at evaluating whether single nucleotide polymorphisms in VDR gene were associated with susceptibility to vascular dementia (VaD) due to cerebral small vessel disease (SVD). A total of 644 subjects (302 patients diagnosed with cerebral SVD-associated VaD and 342, age- and gender-matched healthy controls) were genotyped for VDR gene variants, FokI, ApaI, TaqI and BsmI, by PCR-RFLP method. Among the 4 examined VDR variants, the presence of the minor allele (Ff+ff vs FF) of FokI variant increased the risk for cerebral SVD by 1.5-fold in men (p = 0.047). Serum 25-hydroxyvitamin D [25(OH)D] was lower in subjects having the FokI “ff” genotype compared to those with the “FF” genotype (p = 0.044). Moreover, in subjects with low serum 25(OH)D the presence of “ff” genotype increased the odds of SVD by 2.5 folds (p = 0.041). ApaI polymorphism decreased the risk of cerebral SVD in women. The distribution of TaqI and BsmI variants were not significantly different between patients and controls. Further studies in large cohorts are necessary to validate the role of FokI polymorphism in cerebral SVD and VaD etiopathogenesis.
