Items in categories: Diabetes + Pregnancy + Vitamin D Receptor are listed here:
- Gestational Diabetes – increased risk if poor Vitamin D Receptor – 2 Meta-Analyses 2021
- Gestational Diabetes 2.4X more likely if poor Vitamin D Receptor (region in China) – June 2019
- Gestational Diabetes 3 X more likely if poor Vitamin D receptor (Turkey) – May 2019
- Gestational Diabetes Mellitus associated with 4 Vitamin D genes – Oct 2015
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
Increased risk of diseases if poor VDR
Increased risk associated with a poor Vitamin D Receptor
Note: Some diseases reduce VDR activation
those with a * are known to decrease activation
BACKGROUND:
The association between the vitamin D receptor (VDR) gene and gestational diabetes mellitus (GDM) has not been investigated in Turkish pregnant women. We aimed to investigate associations between VDR gene BsmI (rs15444410), ApaI (rs7975232), FokI (rs19735810), and TaqI (rs731236) single nucleotide polymorphisms (SNPs) and GDM.
MATERIAL-METHODS:
This case-control study comprised 100 women with GDM and 135 pregnant women without GDM. The VDR polymorphism was evaluated using Sanger-based DNA sequencing.
RESULT:
VDR gene ApaI, BsmI, and TaqI SNPs did not differ between women with and without GDM (each, p > 0.05). ApaI, BsmI, and TaqI were not associated with GDM risk. The VDR gene FokI CT/TT genotype was associated with an increased GDM risk
- (CT vs. CC, OR = 1.84, 95% CI: [1.05-3.23], p = 0.031;
- TT vs. CC, OR = 3.95, 95% CI: [1.56-9.96], p = 0.002;
- CT/TT vs. CC, OR = 2.29, 95% CI: [1.35-3.89], p = 0.002; and
- CT/CC vs. TT, OR = 3.02, 95% CI: [1.23-7.38], p = 0.012).
The FokI-TT genotype was more associated with younger age and higher glucose, HbA1c, and HOMA-IR than the CC and CT genotype. FokI-T was positively correlated with log-HOMA-IR (r = 0.326, p = 0.004). FokI SNPs were independently associated with GDM after adjusting for BMI and age (β = 1.63, 95% CI: [1. 2-4.2], p = 0.012). There were no associations between the FokI, ApaI, BsmI and TaqI haplotypes and GDM.
CONCLUSION:
VDR gene FokI SNPs were independently associated with having GDM in Turkish women. VDR gene FokI SNPs might contribute to insulin resistance of developing GDM.
