> Considering how relatively safe Vitamin D is Vitamin D (like Vitamin A) accumulates in the body and is dangerous in high doses.

  It's pretty mild compared to A, with a large gap between the UL and getting sick. Healthy adults need a few months on a dose two orders of magnitude higher than the typical recommendation to see overt toxicity. All known cases of toxicity stem from people going ten times the UL. Still, don't handle this like a water soluble vitamin. Never think about bulk powders, since the IU-to-weight conversion ratio is crazy potent.

    What is the meaning of UL?
    • transit 6y ago
      Tolerable Upper Intake Level, as set by the Institute of Medicine in the US or the European Food Safety Authority. Currently 100 µg/d (4000 IU) for vitamin D.

  I ramped up to 60k IU's per day. No issues thus far. It's been a few years to get to this point. I also take a lot of K2 MK-7, Magnesium, C, Zinc. Well, a bit of everything. AMA.
