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 - 120 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

Note the assumption, which may be correct, that the immune system only responds to tissue Vitamin D, rather than from blood vitamin D

Genes on the web

  • The Genes That Never Go Out of Style Sept 2018
    about 16% of all genes were known by 1991; that same 16% are the focus of half of all Genetics papers in 2015
    25% of all genes have never been the focus of a single scientific paper
    "Even supposedly game-changing techniques like CRISPR have altered the landscape of gene popularity very little"
