Last week, Danish Healthy Authority published a letter warning people not to use Inno Pharma's Vitamin D3 after the supplement was found to have a 75 times higher dose than intended.
According to the Denmark-based manufacturer of dietary supplements, at least 150 children used the super strength vitamin D and more than a dozen have been hospitalized. High vitamin D levels can cause high blood calcium as well as kidney stones.
Inno says production has been halted and the product is being recalled.
