Vitamin D levels massively changed by CYP3A4 gene (drugs such as Ivermectin and anti-epileptics)

Deactivation of CYP3A4 by drugs such as Ivermectin INCREASE calcitriol and calcidriol (Vitamin D)
Activation of CYP3A4 by drugs such as some anti-epileptics DECREASE calcitriol and calcidriol (Vitamin D)

Vitamin D blood test misses a lot
in Visio for 2023

  • 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

  • CYP3A4 Wikipedia
    • CYP3A4metabolizes about half of all drugs: examples include:acetaminophen, codeine, ciclosporin (cyclosporin), diazepam, and erythromycin
    • grapefruit juice ... is a potent inhibitor of CYP3A4, which can affect the metabolism of a variety of drugs, increasing their bioavailability.
