Only recently again I read in the newspaper, that most products are overdosed. There is a typical number that the vitamin D products usually show, and in the article it said, that only up to 800 IU is safe, and everything above is an overdose. There are many products out there with 2000 UI or maybe even more. Beware.

EDIT: Wow, the HN-local doctors at it again. Imagine getting downvoted for sharing information from newspaper article (and honestly labeling that info as such), that probably was written by someone consulting medical professionals. But hey HN will know better!
