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
Blood Test Misses a lot (VDW 3439)

  • 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
    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

  • 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.
