Celiac.com 06/24/2010 - I have previously suggested vitamin D deficiency and the makeup of gut bacteria during pregnancy and infancy, while breast-feeding and prior to and during the introduction of gluten, may be factors leading to the onset of celiac disease. The question of how much vitamin D should be given to infants remains open. The current recommendation, by the American Academy of Pediatrics, is that children of all ages should receive 400 IU of vitamin D each day. A recent limited study of 74 diabetic children, however, suggests that this recommended dose may still be insufficient for most children. The children were given daily vitamin D doses ranging from 400 IU to 2000 IU over a 12-month period and their vitamin D status was monitored. Most of the children remained vitamin D insufficient or deficient at the end of the study. The study concluded that all children younger than 5 years should probably receive at least 1000 IU of vitamin D daily. Further study is needed, especially with specific emphasis on the onset and prevention of celiac disease during infancy.
