Vitamin D blood test misses a lot
- Snapshot of the literature by Vitamin D Life as of early 2019
- Vitamin D from coming from tissues (vs blood) was speculated to be 50% in 2014, and by 2017 was speculated to be 90%
- Note: Good blood test results (> 40 ng) does not mean that a good amount of Vitamin D actually gets to cells
- A Vitamin D test in cells rather than blood was feasible (2017 personal communication)
- Commercially available 2019
- However test results would vary in each tissue due to multiple genes
- Good clues that Vitamin D is being restricted from getting to the cells
1) A vitamin D-related health problem runs in the family- especially if it is one of 51+ diseases related to Vitamin D Receptor
2) Slightly increasing Vitamin D show benefits (even if conventional Vitamin D test shows an increase)
3) Vitamin D Receptor test (<$30) scores are difficult to understand in 2016- easier to understand the VDR 23andMe test results analyzed by FoundMyFitness in 2018
4) Back Pain- probably want at least 2 clues before taking adding vitamin D, Omega-3, Magnesium, Resveratrol, etc

INTRODUCTION:
Low level of vitamin D is a potential risk factor for developing schizophrenia. Through interaction with its receptor (VDR) and the related enzymes (CYP27B1, CYP24A1), vitamin D modulates neurodevelopment, neuroprotection, and immunomodulation. Its deficiency leads to aberrant neurodevelopment in schizophrenic patients.METHODS:
In this case-control study, relative expression of VDR, CYP27B1, and CYP24A1 in schizophrenic patients was compared with healthy individuals. Total RNA was extracted from whole blood of 50 patients with schizophrenia and 50 healthy controls. Real-time PCR was used to determine relative gene expression levels of VDR, CYP27B1, and CYP24A1.RESULTS:
Significant upregulations were observed in VDR (P=0.004, 95% CI=0.77, 0.86), CYP27B1 (P=0.002, 95% CI=1.22, 4.98), and CYP24A1 (P≤0.0001, 95% CI=-2.721, 1.061) expressions in peripheral blood of schizophrenic patients compared with controls. Moreover, the gender-based analysis revealed upregulation of all genes in all the categories of male and female except for VDR gene in male group (P=0.234, 95% CI=-0.79, 3.35) and CYP27B1 gene in the female group (P=0.09, 95% CI=-0.21, 6.55). The age-based analysis demonstrated overexpression of VDR and CYP27B1 genes in all categories. Finally, there were significant correlations between expression levels of all genes (P<0.0001), while no correlation was found between age and expression of genes.CONCLUSION:
We hypothesized that the observed upregulation of the mentioned genes in schizophrenia patients might be the result of a compensatory mechanism to protect the affected individuals against adverse consequences of this disorder. Such imbalance in vitamin D processing pathway might also be implicated in the pathogenesis of schizophrenia. However, future studies should be designed to confirm the results of the current study.Body may change gene activation if more Vitamin D is needed by tissue (Schiz. in this case) – Oct 20181820 visitors, last modified 07 Oct, 2019, This page is in the following categories (# of items in each category)Genetics266 Cognitive 290 Vitamin D Receptor 384 CYP27B1 35 Attached files
