I live in a place where there is very little sunlight during the winter, and take occasional vitamin D supplements. My supplement is 1000 IU. I took a look on amazon and of the first page of results, most were 1000IU and some were 2500 IU
It sounds like the upper end of the recommended range for Vitamin D blood levels is much higher than it should be, and that is the primary reason the person mentioned here had the problems she had, but it also just seems like common sense that you're taking 2-5 times the normal supplementation dose of something, daily, for 5 years you should have a very good reason to do so.
I'm curious if taking 1000 IU every few days could cause similar issues in people who aren't in the sun all day every day.
