Vitamin D blood test misses a lot

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 the 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
- The founder of Vitamin D Life took action with clues #3&5
Many reasons for the decrease in Vitamin D getting to blood and cells

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"
