    Why the hell would you do that?

    Looks like ~4000IU a week is plenty, even with no sunlight exposure.

    You’re looking at like 13x the recommended intake; that’s going to screw up your calcium levels eventually. And the stuff is cumulative, it’s not like eg. vitamin C, which is gone from your system a day later.

    My very strong advice would be don’t.

    If you’ve got a massive deficiency, follow medical advice.

    If you haven’t, then quit fucking with it.

      It is for some people. I currently need to take 100k iu/week in order to be on the low end of normal.

      I was on 150k iu, but I had to switch doctors. The new idiot didn’t believe me and just told me take an OTC pill a day.

      I left that guy. The next time I got checked, I was in the single digits. The new one didn’t really believe me either. Each winter visit I’ve been low and she just keeps adding another pill. I suspect I’ll be back up to 150k then.

    Probably more wasteful than anything. Vitamin D3 is pretty safe, and that’s not a crazy dose for a serious deficiency. It’s probably worth getting tested for your level and dropping to about half that if you aren’t low.

    That is a perfectly reasonable amount of vitamin D to take weekly. If taken orally not all of it will be absorbed anyway.

      I was of the understanding that D3 is lipophillic to the extent that it would likely just be absorbed into and leeched from fat over time. I’m not well read on the literature

        Before vitamin D can be stored in fat it must first be absorbed from the digestive system into the bloodstream. The absorbtion efficiency varies by individual but no one absorbs 100%. After making it into the blood some excess vitamin D can be stored in fat cells for later use.
