Word of caution JK. I was put on 50,000 IU from my doctor and I took 3-4 months to recover from what it did to me. Now this is also related to my problem metabolising, so that would have added to the problem. But because they are not water soluable, they can store and build up and if your body cannot metabolise/detox properly, you can wind up poisoned.

I was poisoned by it. Even a mainstream doctor admitted that my symptoms coincided with vitamin D toxicity and he put it down to me not being able to metabolise properly. However, I also put it down to too much, too soon, of supplemental vitamin D by a previous doctor who should have known better and should have taken the "first do no harm" approach. There are other ways I'm sure to gradually build up vitamn D in the body without taking an extreme approach.

So at least you're not taking things to the extreme dosage wise. I am not the only one who has experienced this. There are others also that have gone through it. So it may not be simply down to my issues with detox/metabolising. May simply be a case of overdosing.
