It may be more important to test Vit. D Receptor than to test Vit. D blood level
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
A poor VDR increases the risk of 30+ health problems click here for details
VDR at-home test $29 - results not easily understood in 2016
There are hints that you may have inherited a poor VDR
You can compensate for poor VDR by increasing one or more of the following:
|1) Vitamin D supplement|
Sun, Ultraviolet -B
| Vitamin D in the blood |
and thus to the cells
|2) Magnesium||Vitamin D in the blood |
AND to the cells
|3) Omega-3||Vitamin D to the cells|
|4) Resveratrol||Vitamin D to the cells|
|5) Intense exercise||Vitamin D Receptor|
|6) Get prescription for VDR activator|
|Vitamin D Receptor|
|7) Quercetin (flavonoid)||Vitamin D Receptor|

Vitamin D receptor (VDR) is expressed in the placenta and tissues related to the immune system occurrence of various variants of VDR may modify the effects of vitamin D on pregnancy. The aim of this study was to evaluate the association between the parturients' Apa1, Taq1, and Bsm1 polymorphisms of the VDR and their combinations and the risk of preterm birth in the Polish population.
MATERIAL AND METHODS:
Determination of polymorphism for VDR was assayed using the RT-PCR method. 199 Caucasian women at childbirth were qualified:100 patients who had a spontaneous preterm birth and 99 patients who had a term birth.
Three separate genotypes of the Apa1, Taq1, and Bsm1 polymorphisms were detected. No significant differences in the frequency of particular genotypes in the compared groups were found. Some of the genotype combinations were significantly more frequent in the preterm group - the bb/AA/TT genotype (28.0% vs. 10.1%; p = 0.0013) and the BB/aa/tt genotype (14.0% vs. 4.04% p = 0.0277). The Bb/AA/Tt and the BB/Aa/tt genotypes were found only in the control group (16.1% and 7.0% of patients, respectively). The bb/aa/TT was significantly more frequent in the control group (2.0% vs. 11.1%; p = 0,0207).
Two genotype combinations reduced the risk of preterm birth - the
- Bb/AA/Tt genotype by 94% (OR = 0.43, 95% CI: 0.002-0.885, p = 0.041) and the
- BB/Aa/tt genotype by 98% (OR = 0.029, 95% CI: 0.001-0.838, p = 0.039).
Our result suggests that there may be a relationship between certain VDR genotype combinations and the risk of preterm birth. Further research is needed in order to substantiate this finding.
