Pages listed in BOTH the categories Pregnancy and Vitamin D Binding Protein
- Hypertension during pregnancy: low Vitamin D, poor Vit. D genes – June 2022
- During pregnancy less Vitamin D due to increased Vitamin D binding Protein – May 2020
- Spontaneous Miscarriage strongly associated with 2 vitamin D genes – March 2020
- Preeclampsia 11X more likely if poor Vitamin D Binding Protein (South Africa) - Sept 2019
- Type 1 Diabetes risk increased if high postpartum Vitamin D binding protein – Jan 2019
- Fetal Growth poor if Vitamin D-Binding Protein gene poor – Feb 2017
- Gestational Diabetes Mellitus associated with 4 Vitamin D genes – Oct 2015
- Preeclampsia changes to Vitamin D Binding Protein reduces Vitamin D in placenta – Dec 2016
- Bio-available Vitamin D is reduced by half during pregnancy – Jan 2017
- Changes during pregnancy of vitamin D (decrease), DBP (2X) and albumin (0.8X) – Oct 2014
Vitamin D Binding Protein category listing has 178 items and the following introduction
Vitamin D Binding Protein (GC) gene can decrease the bio-available Vitamin D that can get to cells,
- GC is not the only such gene - there are 3 others, all invisible to standard Vitamin D tests
- The bio-available calculation does not notice the effect of GC, CYP27B1, CYP24A1, and VDR
- The actual D getting to the cells is a function of measured D and all 4 genes
- There is >2X increase in 8+ health problems if have poor VDBP (GC)
- It appears that VDBP only blocks oral vitamin D,
- but NOT Vitamin D from sun, UV, topical or inhaled (tissue activated)
- A clue: - Vitamin D from UV is 2X better for MS than oral Vitamin D
Note: Topical Vitamin D does not appear to be blocked by VDBP

Vitamin D-binding protein (VDBP), the main carrier of vitamin D, has recently been implicated in reproductive health and pregnancy outcomes including endometriosis, polycystic ovary syndrome (PCOS), pre-eclampsia, and gestational diabetes mellitus (GDM). Improved methods for measuring VDBP and an increased understanding of its role in biological processes have led to a number of newly published studies exploring VDBP in the context of pregnancy. Here, we synthesize the available evidence regarding the role of VDBP in reproductive health and pregnancy, and we highlight areas requiring further study. Overall, low levels of maternal serum VDBP concentrations have been associated with infertility, endometriosis, PCOS and spontaneous miscarriage, as well as adverse pregnancy outcomes including GDM, pre-eclampsia, preterm birth and fetal growth restriction. However, increased VDBP concentration in cervicovaginal fluid has been linked to unexplained recurrent pregnancy loss and premature rupture of membranes. Some genetic variants of VDBP have also been associated with these adverse outcomes. Further studies using more accurate VDBP assays and accounting for ethnic variation and potential confounders are needed to clarify whether VDBP is associated with reproductive health and pregnancy outcomes, and the mechanisms underlying these relationships
