TUESDAY, April 30 (HealthDay News) -- Ideal amounts of vitamin D
supplementation for breast-feeding infants are unclear, according
to a new study.
Vitamin D is important for infant bone growth, but
breast-feeding infants are susceptible to vitamin D deficiency due
to low levels of the vitamin in breast milk, according to
background information included in the study, which was published
in the May 1 issue of the
Journal of the American Medical Association.
The study, by Hope Weiler and colleagues at McGill University in
Montreal, included 1-month-old healthy breast-fed infants who were
followed for 11 months after being randomly assigned to receive
different dosages of oral vitamin D supplements. Doses were either
400, 800, 1,200 or 1,600 international units per day.
None of the dosages raised and maintained vitamin D levels
within a range recommended by some pediatric societies, but all the
dosages raised and maintained vitamin D levels within a lower range
recommended by the Institute of Medicine, according to a journal
The study did not pinpoint the ideal dose of vitamin D for
infants, Dr. Steven Abrams, of Baylor College of Medicine in
Houston, said in an accompanying journal editorial. He wrote,
however, that clinicians could be reassured from the findings that
a daily vitamin D intake of 400 international units was adequate to
maintain blood levels recommended for bone health.
