What is the recommended daily intake of vitamin D for breastfed infants?

The recommended daily intake of vitamin D for breastfed infants is 400 IU (International Units). This amount is essential because breast milk typically does not provide sufficient vitamin D to meet an infant's needs. Vitamin D is crucial for bone health and helps in the absorption of calcium and phosphorus in the body.

The recommendation of 400 IU is based on evidence that this amount effectively prevents rickets and promotes overall health in infants. It is particularly important for those who are exclusively breastfed, as they may not receive adequate sun exposure to synthesize vitamin D naturally.

This guidance aligns with recommendations from pediatric health organizations, which emphasize the need for vitamin D supplementation starting shortly after birth, especially for infants who are not receiving formula that is fortified with vitamin D.
