To evaluate association of vitamin D with sleep quality in adults and the influence of VDR-gene polymorphism FokI (rs2228570;A > G). Cross-sectional population-based study in adults, conducted in Brazil. The outcome was sleep-quality, evaluated by the Pittsburgh Sleep Quality Index. Vitamin D was determined by indirect electrochemiluminescence and classified as deficiency (VDD), 25(OH)D < 20 ng/mL in a healthy population or 25(OH)D < 30 ng/mL for groups at risk for VDD. FokI polymorphism in the VDR-gene was genotyped by qPCR and classified as homozygous wild (FF or AA), heterozygous (Ff or AG), or homozygous mutant (ff or GG). Multivariate logistic analysis was used to estimate the association between vitamin D and FokI polymorphism with sleep-quality.
In a total of 1674 individuals evaluated, 53.6% had poor-sleep-quality, 31.5% had VDD, and the genotype frequency of the FokI polymorphism was 9.9% FF, 44.6% Ff, and 45.5% ff.
In multivariate analysis, individuals with VDD had 1.51 times the chance of poor-sleep-quality, and individuals with the ff genotype had 1.49 times the chance of poor-sleep-quality (OR:1.49;95%CI:1.05-2.12) when compared to individuals with the FF or Ff genotype.
In the combined analysis, individuals with VDD and ff genotype had more chance of poor-sleep-quality than individuals with sufficient vitamin D and genotype Ff or FF (OR:2.19;95%CI:1.27-3.76). Our data suggest that VDD and VDR FokI gene polymorphism are associated with poor-sleep-quality, and combining the two factors increases the chance of poor-sleep-quality compared to separate groups.

102 items in sleep category

A few items in SLEEP category

• Sleep greatly improved by 50,000 IU of vitamin D once every two weeks – RCT Sept 2018
• Sleep disorders nicely treated by Vitamin D (50,000 IU twice a month) – RCT May 2017
• Sleep, Dr. Gominak and Vitamin D - several studies

VitaminDWiki - The risk of 50+ diseases at least double with poor Vitamin D Receptor

VitaminDWiki - Vitamin D Receptor activation can be increased in many ways

Resveratrol,  Omega-3,  Magnesium,  Zinc,   Quercetin,   non-daily Vit D,  Curcumin,   Berberine,  intense exercise, Butyrate   Sulforaphane   Ginger,   Essential oils, etc  Note: The founder of VitaminDWiki uses 10 of the 16 known VDR activators

VitaminDWiki – Vitamin D Receptor category contains

532 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 (14 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

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
