Objective: Growing evidence has shown that vitamin D deficiency can cause lower bone mineral density (BMD) and an increased risk of osteoporosis. Vitamin D receptor (VDR) BsmI polymorphism (rs1544410) can affect BMD variation and circulating osteocalcin levels. To date, a wide range of epidemiological studies have been carried out to evaluate the association between VDR BsmI polymorphism and susceptibility to osteoporosis. Conflicting results, however, were obtained. The aim of this study was to evaluate the effect of VDR BsmI polymorphism on osteoporosis risk using a meta-analysis.

Methods: Twenty-six publications were identified by searching PubMed and Embase databases. The association between VDR BsmI polymorphism and osteoporosis was estimated by calculating pooled odds ratios (ORs) with corresponding 95% confidence intervals (Cis).

Results: The bb genotype was associated with a significantly decreased risk of osteoporosis in overall comparison (

• bb vs. BB: OR=0.61, 95% CI, 0.40–0.92;
• bb vs. BB/Bb: OR=0.70, 95% CI, 0.52–0.95, respectively).

Subgroup analyses showed that the bb genotype had a decreased risk of developing osteoporosis in

• postmenopausal women (bb vs. BB/Bb: OR=0.68, 95% CI, 0.46–0.98) and
• Africans (Bb/bb vs. BB: OR=0.18, 95% CI, 0.09–0.37).

Conclusion: The VDR BsmI polymorphism may have a protective role against the development of osteoporosis.

Vitamin D Receptor category has the following

384 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
It appears that 30% of the population have a poor VDR (40% of the Obese )

A poor VDR increases the risk of 55 health problems  click here for details
The risk of 44 diseases at least double with poor Vitamin D Receptor as of Oct 2019

VDR at-home test $29 - results not easily understood in 2016
There are hints that you may have inherited a poor VDR

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 in the cells
13) Sulfroaphone and perhaps sulfur	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
