Vitamin D Life Summary

Facts about Vitamin D activation

  • Vitamin D must be activated before a majority of the benefits can be realized
  • Vitamin D can be activated by Liver & Kidney and put into the bloodstream
  • Vitamin D can also be activated locally by most tissues in the body
    Local activation is not detected by Vitamin D tests
  • Vitamin D is activated by the fetus sometime during gestation

Possibilities

  1. Placenta itself needs activated vitamin D all during gestation
  2. Fetus needs activated vitamin D before it’s liver and kidneys start functioning
       during the time in which miscarriages typically occur

CYP27B1 RNA

Tissues Control Primary miscarriage, Recurrent miscarriage P
Villous 1.20 0.81 0.40 0.000
Decidual 1.35 1.20 0.44 0.003

Easy options to avoid miscarriages due to CYP27B1 restriction

  1. Increase blood-levels of Vitamin D
    e.g. Increase some/all of vitamin D supplements, sunshine, UV, Magnesium, Boron, Omega-3
  2. Increase Vitamin D Receptor (which results in more Vitamin D getting into cells)

Vitamin D blood test misses a lot
Blood Test Misses a lot (VDW 3439)

  • 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
    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

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:

4) Resveratrol Vitamin D Receptor
5) Intense exercise 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

BACKGROUND:
Effects of vitamin D deficiency in pregnancy have been associated with some adverse pregnancy outcomes. The 25-hydroxyvitamin D3-1α-hydroxylase (CYP27B1) is integral to the vitamin D metabolic pathway. The enzyme catalyzes localized conversion of pro-hormone 25-hydroxyvitamin D3 to active 1,25-dihydroxyvitamin D3. Our aim was to investigate the expression of CYP27B1 at the fetal-maternal interface in the first trimester pregnancy and to determine whether CYP27B1 was associated with recurrent miscarriage (RM).

METHODS:
Expressions of CYP27B1 mRNA and protein in villi and decidua from 20 women undergoing primary miscarriage, 20 women with RM and 20 women with normal pregnancy were evaluated by western blot, and quantitative real-time PCR. The co-localization of CYP27B1 and certain cytokines including IL-10, IFN-γ, TNF-α, and IL-2 expression were examined using immunohistochemistry and confocal microscopy.

RESULTS:
Women with RM had a significantly lower expression of CYP27B1 mRNA and protein in villous and decidual tissues compared with the normal pregnant women (P = 0.000 in villus, P = 0.002 in decidua for mRNA; P = 0.036 in villus, P = 0.007 in decidua for protein.). Compared with the normal pregnancy, immunostaining for CYP27B1 was significantly decreased in villous trophoblasts and decidual glandular epithelial cells in RM women. No significant differences in the localization of CYP27B1, IL-10, IFN-γ, TNF-α, and IL-2 expression were identified between the normal pregnant and RM women.

CONCLUSIONS:
Women with RM have a lower level of CYP27B1 expression in chorionic villi and decidua compared with normal pregnant women, suggesting that reduced CYP27B1 expression may be associated with RM. The consistent localization of CYP27B1 and IL-10, IFN-γ, TNF-α, and IL-2 expression in villous and decidual tissues suggests the importance of the local production of 1,25(OH)2D3 at the fetal-maternal interface to regulate cytokine responses.
