We and others have suggested that vitamin D receptor gene (VDR) polymorphisms influence susceptibility for Parkinson's disease (PD), Alzheimer's disease (AD), mild cognitive impairment (MCI) or overall cognitive functioning. Here we examine VDR polymorphisms and cognitive decline in patients with PD. Non-Hispanic Caucasian PD patients (n=190) in the Parkinson Environment Gene (PEG) study were successfully genotyped for seven VDR polymorphisms. Cognitive function was assessed with the Mini-Mental State Exam (MMSE) at baseline and at a maximum of three follow-up exams. Using repeated-measures regression we assessed associations between VDR SNP genotypes and change in MMSE longitudinally. PD cases were on average 67.4 years old at diagnosis and were followed for an average of 7.1 years into disease.
Each additional copy of the FokI A allele was associated with a 0.115 decrease in the total MMSE score per year of follow-up (β=-0.115, SE(β)=0.05, p=0.03) after adjusting for age, sex, education and PD duration. The effect on MMSE by the FokI A allele was comparable in absolute magnitude to the effect for disease duration in years prior to first interview (β=-0.129 per year, SE(β)=0.08, p=0.13), and years of education (β=0.118 per year, SE(β)=0.03, p<0.001). When LD/LED use and PD subtype were added to the model, the effect of the FokI A allele on total MMSE score was magnified (β=-0.141, SE(β)=0.05, p=0.005). Results point to Fokl, a functional VDR polymorphism, as being associated with cognitive decline in PD. Future studies examining the contributions of the vitamin D metabolic pathway to cognitive dysfunction in PD are needed.

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
Overview Parkinson's and Vitamin D contains the following summary
- Vitamin D associated with Parkinson’s Disease in 55 studies, more studies needed- March 2022
- Parkinson's category has
117 studies - Parkinson’s Disease and Vitamin D – review of 52 studies – May 2022
- Parkinson patients: 60 % taking Vitamin D – Dec 2019
- Low Vitamin D increases Parkinson's by 3X– July 2010 "only" a 30 year test, need more study
- Parkinson's disease prevented by Vitamin D, but small doses do not treat it - Aug 2023
- 10 clinical trials for PD with vitamin D intervention as of June 2023
- Parkinson’s Disease Summer School – alternative therapies included 60-80 ng of Vitamin D – Sept 2019
- Associated with PD are: Meta-analyses (
12 ), Cognition ( 24 studies), Multiple Sclerosis ( 18 studies), VIRUS ( 4 studies), Omega-3 ( 3 studies), Vitamin D Receptor ( 11 studies) - Note by the Founder of VitaminDWiki: I have twice recommended lots of Vitamin D to treat PD. Both got much better, but one had his doctor him cut back to just 2,000 IU. All of his recovery got reversed. With lots of vitamin D he could sing and bike, but now he can barely talk or walk
