Virtually all Vitamin D trials have been based on Vitamin D blood tests
There are at least 4 genes which can restrict the amount of vitamin D in the blood which can get to the tissues

Vitamin D blood test misses a lot
in Visio for 2023

  • 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 shows benefits (even if conventional Vitamin D test shows an increase)
    3) DNA and VDR tests - 100 to 200 dollars $100 to $250
    4) PTH bottoms out ( shows that parathyroid cells are getting Vitamin d)
       Genes are good, have enough Magnesium, etc.
    5) Back Pain
       probably want at least 2 clues before taking adding vitamin D, Omega-3, Magnesium, Resveratrol, etc

CYP27B1 category listing contains the following

The CYP27B1 gene activates Vitamin D in the Kidney,    Skin,    Lungs,    Brain,   Eyes   Breasts   etc.
Poor CYP27B1 is assocated with COVID, Miscarriage,   Lupus,   Alz, Parkinson, MSA,   Rickets

CYtochrome P450 family 27 subfamily B member 1    = 25-Hydroxyvitamin D3 1-alpha-hydroxylase

What can be done if have a poor CYP27B1

  • Larger doses of Vitamin D
  • More Bio-available: Gut-friendly form, Topical form, taken with fatty meal, taken with evening meal
  • Additional sources: UV
  • Increase Vitamin D metabolism: additional Magnesium, Omega-3
    • All cytochrome P450 enzymes require Mg++ as a cofactor
  • Increase the amount of Vitamin D in the blood that gets to cells: increase activation of VDR

Summary
The interest in Vitamin D (Vit D) is increased after the finding of Vit D receptors in many different cells. This led to the hypothesis that Vit D may have more impact on human health than its role in bone health. Epidemiological studies found associations between low plasma levels of Vit D and the prevalence of many diseases. However, Large RCTs did not find convincing evidence for a positive effect of Vit D supplementation on cancer, cardiovascular disease, auto-immune disease and inflammatory diseases. In this review, the results are described of a literature search regarding the relationship between Vit D status and different diseases.

Pubmed was used to find systematic reviews of observational studies describing the association between Vit D status, diseases (cancer, coronary heart diseases, auto-immune diseases, sepsis) and mortality. Subsequently, a search was performed for RCTs and the results of large RCTs are described. Studies with a positive intervention effect on primary or secondary outcome variables are summarized. No exclusion criteria were used.

The metabolism of Vit D is reviewed, its endogenous production and the intake from food, its activation and transport in the body. The article addresses the effects of diseases on the metabolism of Vit D with special focus on the role of Vit D Binding Protein and its effects on assessing Vit D status. Studies addressing the association between vitamin D status and cancer, cardiovascular diseases, auto-immune diseases, inflammation and severe illness are reviewed. A search for RCTs with positive effects of Vit D supplementation on different diseases yielded only a few studies. The vast majority of RCTs showed no significant positive effects. The presumed high prevalence of Vit D deficiency is questioned based on these results and on altered concentrations of Vit D binding protein, leading to low Vit D levels in plasma but not to low active Vit D levels during disease related inflammation In these conditions, plasma levels of Vit D are therefore not a valid reflection of Vit D status. Reversed causality is described as a possible factor interfering with the correct assessment of the Vit D status. It is concluded that further widespread fortification of foods and stimulation of supplement use should be reconsidered.
