Hypervitaminosis D is one of the causes of severe hypercalcemia in children. Most cases of hypervitaminosis D during childhood are due to an excessive supplementation of vitamin D by physicians or parents.1,2
To prevent metabolic bone disease of prematurity (rickets of prematurity), formulas designed for premature infants ("premature formulas"), which contain more calcium and vitamin D than standard formulas, are given to premature infants in addition to human milk.1 In some cases, separate vitamin D products are also given to these infants, although requirements for vitamin D and calcium intake in the premature infant and the formerly premature infant have not been fully estimated.1
