The minimum daily recommended amount of vitamin D has been reassessed recently and raised from 200 to 400 IU for exclusively breast-fed infants. However, these amounts may not be sufficient to bring infant vitamin D stores to repletion. Several studies have assessed the vitamin D status of exclusively breast-fed infants and found infants to be vitamin D deficient, regardless of access to proper sunlight exposure and supplementation. © 2011 Lippincott Williams & Wilkins, Inc.
