Genes evolve to adapt to excess or low vitamin D (Eskimo, Reindeer, etc.) – June 2019

Note: It probably takes many 1,000's of years for the genes to adapt

• Eskimos evolved to get and limit Vitamin D from food
• Inuit and vitamin D

Reindeer genes are 20X better at activating Vitamin D than other mammals

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

• Snapshot of the literature by Vitamin D Life as of early 2019
• 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 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 Vitamin D Life took action with clues #3&4
