Optimal vitamin D dosage for infants uncertain
Date:4/30/2013

dings of this study in an accompanying editorial.

"The data reported by Gallo et al do not answer the question of what the target should be for plasma 25(OH)D concentration. If the target is 75 nmol/L or higher, then vitamin D intake of 400 IU/d is not enough for a substantial proportion of infants, especially those in northern parts of the United States or in Canada or who have darker skin pigmentation. However, another question that needs to be answered is whether there are non-bone health reasons to target a plasma 25(OH)D concentration greater than 75 nmol/L. Answering such questions about non-bone health aspects of vitamin D nutrition can be accomplished only by rigorous clinical trials that include enough participants and establish clear outcomes before the study begins."

"Pending such information, clinicians can be reassured by the findings from the study by Gallo et al that a daily vitamin D intake of 400 IU/d in infants, as currently recommended, leads to adequate plasma 25(OH)D concentration for identified physiological functioning related to bone health."
