Abstract
The last guidelines of the American Academy of Pediatrics for prevention of vitamin D deficiency
in infants, children, and adolescents recommend a minimum daily intake of 400 IU
of vitamin D beginning soon after birth. All breastfed and partially breastfed infants, as
well as all nonbreastfed infants ingesting <1 liter per day of vitamin D fortified formula or milk
should receive a vitamin D supplement of 400 IU per day. The intake of 400 IU of vitamin
D per day has showed to maintain serum 25-hydroxyvitamin D (25-OH-D) levels ≥20 ng/ml
in exclusively breastfed infants. It should be the “desiderable” value of 25-OH-D in infants,
children, and adolescents. Vitamin D deficiency has been also associated with increased risks
of some cancers, some cardiovascular diseases, multiple sclerosis, rheumatoid arthritis,
type I diabetes mellitus, senile osteoporosis, and other pathologies. Thus, vitamin D supplementation
should not only be restricted to prevention of rickets. Many preparations for prevention
of vitamin D deficiency are available in Italy. The vitamin D-only preparations are particularly
appropriate to provide vitamin D supplements. Moreover, the amount of vitamin D
supplements (400 IU/day) should be easily computable and restricted in a relatively small
volume. Vitamin D metabolites are not indicated for prevention of vitamin D deficiency.
