Vitamin D supplementation leading to hypervitaminosis D in a breastfed infant: A case report

Abstract

Key Clinical MessageBreast milk alone is a poor and inadequate source of vitamin D. Many guidelines suggest supplementation of vitamin D to the newborns to prevent vitamin D deficiency. However, due to practices of outdoor breastfeeding and sunbathing, vitamin D supplementation may not be routinely required in our settings. Overzealous use of vitamin D supplementation and over‐the‐counter prescription may result in hypervitaminosis D.
