The vitamin D receptor (VDR) is a member of the nuclear receptor (NR) superfamily. The VDR binds to active vitamin D3 metabolites, which stimulates downstream transduction signaling involved in various physiological activities such as calcium homeostasis, bone mineralization, and cell differentiation. Quercetin is a widely distributed flavonoid in nature that is known to enhance transactivation of VDR target genes. However, the detailed molecular mechanism underlying VDR activation by quercetin is not well understood. We first demonstrated the interaction between quercetin and the VDR at the molecular level by using fluorescence quenching and saturation transfer difference (STD) NMR experiments. The dissociation constant (Kd) of quercetin and the VDR was 21.15 ± 4.31 µM, and the mapping of quercetin subsites for VDR binding was performed using STD-NMR. The binding mode of quercetin was investigated by a docking study combined with molecular dynamics (MD) simulation. Quercetin might serve as a scaffold for the development of VDR modulators with selective biological activities.

Vitamin D Receptor category has the following

510 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: 47 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 (22 studies), Colon Cancer (13 studies), Cardiovascular (23 studies), Cognition (16 studies), Diabetes (24 studies), Hypertension (9 studies), Infant (21 studies), Lupus (6 studies), Metabolic Syndrome (4 studies), Mortality (4 studies), Multiple Sclerosis (12 studies), Obesity (16 studies), Pregnancy (24 studies), Rheumatoid Arthritis (10 studies), TB (8 studies), VIRUS (36 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:

IncreasingIncreases
1) Vitamin D supplement  Sun
Ultraviolet -B
Vitamin D in the blood
and thus in the cells
2) MagnesiumVitamin 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 VDRVitamin D Receptor
9) BoronVitamin D Receptor ?,
etc
10) Essential oils e.g. ginger, curcuminVitamin D Receptor
11) ProgesteroneVitamin D Receptor
12) Infrequent high concentration Vitamin D
Increases the concentration gradient
Vitamin D Receptor
13) Sulfroaphane and perhaps sulfurVitamin D Receptor
14)Butyrate especially gutVitamin 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
