What is the recommended daily Vitamin D intake for infants from 0 to 12 months?

The recommended daily Vitamin D intake for infants from 0 to 12 months is 400 IUs. This dosage is crucial for ensuring that infants have adequate levels of Vitamin D, which is essential for healthy bone development and immune function. Vitamin D aids in the absorption of calcium and phosphate in the body, which are vital for developing strong bones and teeth.

Breast milk typically contains insufficient amounts of Vitamin D, which is why supplementation is often necessary for exclusively breastfed infants. The recommendation aligns with guidelines from health organizations, including the American Academy of Pediatrics, which emphasize the importance of adequate Vitamin D intake starting shortly after birth. The decision to set the allowance at 400 IUs is based on research indicating that this amount sufficiently supports the prevention of rickets and maintains bone health during the critical growth and development period in infancy.
