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

  • Snapshot of the literature by VitaminDWiki - (subject to many future developments)
  • Vitamin D from coming from tissues (vs blood) was speculated to be 50% in 2014, andi in 2017 is speculated to be 90%
  • Note: Good results from a blood test (> 40 ng) does not mean that a good amount of Vitamin D actually gets to cells
  • A Vitamin D test in cells appears feasible (personal communication)
    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
          The founder of VitaminDWiki took action with clues #3&4

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"
