Vitamin D in Preterm and Full-Term Infants
Vitamin D is necessary for the active (transcellular) absorption of calcium and for skeletal health. Inadequate vitamin D in infants leads to increased risks of poor bone mineralization and ultimately rickets. The usual total dietary intake level of vitamin D should be approximately 400 IU daily in healthy infants. Vitamin D is a critical nutrient for bone health and needs to be provided to all infants whether via infant formula or as a supplement to breastfed infants or high dose supplement to their mothers.
