I used to take one 5000 IU every day, until I got my blood test results back showing 132.9, when the normal range 30-100. I cut back to three a week. We'll see what it looks like next time I get tested.
Vitamin D is not like other vitamins that are water soluble. It is fat soluble and can accumulate in your body.
You should just stop until your level is normal. Fat in your body is probably full of it and it will take a long time for your blood level to come down. If you have problems from having too much vitamin d, consuming green and orange vegetables help.
