Em (and anyone else taking ANY vitamin supplement) be careful about taking so much vit D. According to my nutrition reference/text book, the upper tolerable limit for VitD as a supplement is 50 MICROGRAMS. The abbreviation for that unit looks like this----ug or mcg. And too much can certainly be toxic. It can leach the calcium out of your bones, cause kidney stones, and calcify soft tissues in your body with long term overdosing.
You have fair skin and its good you use suncreen regularly, but it really doesnt take a lot to get your body to make its own vit d from the sun. Just expose your hands, face, and arms for 5-10 minutes 3 times a week.
here's a reference link from a reputable source (i.e. one that is not trying to sell you something)http://ods.od.nih.gov/factsheets/vitamind.asp
edit to add-
IU (international units) is another unit used to measure tiny amounts (i.e. for vitamin reference ranges) mcg and IU are much smaller units than mgs (miligrams) The FDA doesnt regulate vitamin supplements like they do prescription medication, so anyone can sell anything in any amount, but that doesnt mean its good for you.
