Example of gene problem running in a family
CYP24A1 problem allowed Vitamin D to accumulate in the body, resulting in hypercalcemia.
It was discovered that a sibling had the same gene problem
- Vitamin D Heritability: twin studies – 20 percent to 85 percent, GWAS 5 percent – Oct 2018
- Health problems that run in families are often associated with low vitamin D
- Health problems can persist through many generations – Epigenetics and Vitamin D

- Getting Vitamin D into your body
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.
5) 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&5
