Current vitamin D recommendations for infants require a minimum daily intake of how many IU of vitamin D?

• A. 100 IU
• B. 200 IU
• C. 400 IU
• D. 600 IU

Answer: (C)

Vitamin D is essential for calcium absorption and bone mineralization, and infants often don’t get enough from breast milk alone or from limited sun exposure. The established minimum daily intake to reliably support bone health and prevent deficiency in infants is 400 IU per day. This dose helps ensure adequate vitamin D status during rapid growth in infancy, regardless of breast milk or formula intake (with fortified formula supplying some vitamin D as well).
