Note: It probably takes many 1,000's of years for the genes to adapt
Reindeer genes are 20X better at activating Vitamin D than other mammals
Biological adaptations in the Arctic cervid, the reindeer (Rangifer tarandus) - June 2019

POR = P450 Oxidoreductase
Suspect also that Reindeer have gene modifications which increase the Vitamin D half life from ~2 months to > 5 months

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 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.
+4) Back Painprobably want at least 2 clues before taking adding vitamin D, Omega-3, Magnesium, Resveratrol, etc
