Overview Toxicity of vitamin D

Graph of dose vs week


  • Thus the following are safe:
    2 million IU daily for 1 week,
    200,000 IU daily for 1.5 weeks,
    150,000 IU daily for 2 weeks,
    85,000 IU daily for 4 weeks,
    50,000 IU daily for 5 weeks
  • The toxicity reports are generally for Vitamin D monotherapy - at about 2 million IU total dose
  • Magnesium, Vitamin K2, and other COFACTORS will move the curve to the right
  • Also you need to reduce Calcium when having lots of vitamin D
  • True toxicity (with cofactors) is probably much higher than the monotherapy line on the chart

In most cases a doctor will just let the body remove any toxic amount of vitamin D by itself

  • Vitamin D DOES NOT accumulate in the body WikiPedia on Bioaccumulation
  • No medical procedure is needed. The body deals with the excess naturally
