TT increases risk of Alzheimer's

The role of vitamin D in Alzheimer's Disease (AD) has been studied over the past years. The results from numerous studies have indicated that the molecular pathways involved in the development of AD are closely related to the molecular pathways of the mechanisms of action of vitamin D. However, only a limited number of studies have described the key role of vitamin D receptor (VDR) in the regulation of the functions of vitamin D and the potential effect of single nucleotide polymorphisms (SNPs) of the VDR gene. Thus, the aim of the present study was to investigate the VDR TaqI polymorphism in relation to AD in a Southeastern European Caucasian (SEC) cohort. Further, the present study aimed to compare the results obtained with those of other AD populations. For this purpose, blood samples from 90 confirmed patients with AD [median age, 74 years; median mini-mental state examination (MMSE) score of 21; median frontal assessment battery (FAB) score of 10] and 103 healthy controls (median age, 57 years) were analyzed to determine the genotypes of TaqI (rs731236) using quantitative PCR. The frequencies (%) of the TaqI TT, TC and CC genotypes in the controls/patients were 34/48.9, 47.6/41.1 and 18.4/10.0, respectively.
Statistically significant differences were observed for the

• TaqI C allele [odds ratio (OR). 0.54; 95% confidence interval (CI), 0.30-0.96; P=0.035], the
• TaqI TT genotype (OR, 1.86; 95% CI, 1.04-3.32; P=0.035) and the
• TaqI CC genotype (OR, 0.119; 95% CI, 0.014-0.995; P=0.032,)

in relation to the MMSE score <21 in the patient's group.
The TaqI TT allele was found to increase the risk of developing AD by 1.86-fold in the SEC population, while the TaqI C allele may act protectively, with a 46% lower risk of developing the disease. Patients with the TaqI CC genotype were found to have an 88% less likelihood of developing severe cognitive impairment based on the MMSE score. On the whole, the present study did not confirm the results of previous studies on the VDR TaqI C allele in patients with AD.

VitaminDWiki - Vitamin D Receptor category

530 studies in Vitamin D Receptor category

Vitamin D tests cannot detect Vitamin D Receptor (VDR) problems
A poor VDR restricts Vitamin D from getting in the cells

See also: 48 studies in the Resveratrol category

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

Health problems include: Autoimmune (19 studies), Breast Cancer (24 studies), Colon Cancer (13 studies), Cardiovascular (23 studies), Cognition (16 studies), Diabetes (24 studies), Hypertension (9 studies), Infant (22 studies), Lupus (6 studies), Metabolic Syndrome (4 studies), Mortality (4 studies), Multiple Sclerosis (14 studies), Obesity (17 studies), Pregnancy (24 studies), Rheumatoid Arthritis (10 studies), TB (8 studies), VIRUS (37 studies),   Click here for details
Some health problems, such as Breast Cancer, Diabetes, and COVID protect themselves by reducing VDR activation

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

VitaminDWiki - Overview Alzheimer's-Cognition and Vitamin D starts

• FACT: Cognitive decline is 19X more likely if low vitamin D
• FACT: Dementia is associated with low vitamin D levels.
• FACT: Alzheimer’s Dementia 2.3X more likely in elderly if low vitamin D – Dec 2022
• FACT: Dementia is associated with low vitamin D - many studies
• FACT: Alzheimer's Disease is 4X less likely if high vitamin D
• FACT: Every single risk factor listed for Alzheimer's Disease is also a risk factor for low vitamin D levels
• FACT: Elderly cognition gets worse as the elderly vitamin D levels get even lower (while in senior homes)
• OBSERVATION: Reports of increased vitamin D levels result in improved cognition
• OBSERVATION: Alzheimer’s patients 3X more likely to have a malfunctioning vitamin D receptor gene – 2012
• OBSERVATION: Alzheimer's Disease has been seen to halt when vitamin D was added.
