What is the revised recommendation for vitamin D status in infants, including those who are exclusively breastfed?

• A. All infants, including those exclusively breastfed, should receive a minimum of 400 IU per day beginning soon after birth.
• B. Only formula-fed infants should receive 400 IU per day.
• C. Infants should receive 200 IU per day for the first year.
• D. Vitamin D is not routinely required in infants.

Answer: (A)

All infants should receive vitamin D supplementation to ensure bone health and prevent deficiency, including those who are exclusively breastfed. Breast milk often doesn’t provide enough vitamin D, and infants have limited sun exposure, so a daily supplement is required. The standard dose that reliably meets an infant’s needs is 400 IU (10 micrograms) per day, started soon after birth. This universal approach avoids gaps in protection for breastfed babies and remains protective even for those who will be fed fortified formula later on. Some formula-fed infants who consume a full daily amount of fortified formula might obtain vitamin D from the formula, but intake can vary, so continuing 400 IU/day is the safest and simplest recommendation. Lower doses or withholding supplementation entirely would leave infants at risk for deficient vitamin D and related bone problems.
