Vitamin's A, D, and E are fat soluble, so if you get extra, you don't pee it out like with most vitamins. I believe that means that if you take excess, it will store in your fat and build up and you can eventually have too much.

I don't know about the effects of too much D, but my mom started having issues from getting too much E back in the 80s until her Dr told her about it being fat soluble. I've heard that most folks don't get enough D. I've also heard from multiple Drs (MDs) that the commonly recommended amount of D is not adequate.

I've been taking 100-125 mcg (µg) per day (when I remember which is probably 5-6 days/wk) for several years. I believe that's 500-650%DV.
