Vitamin D: New Guidelines for Children
American Academy of Pediatricians Doubles Its Minimum Daily Amount of Vitamin D for Babies, Children, and Teens
Oct. 13, 2008 -- The American Academy of Pediatrics has doubled its
recommendation for the minimum amount of vitamin D that infants, children, and
teens should get daily.
The new recommendation is to get at least 400 international units (IU),
according to guidelines published by the American Academy of Pediatrics (AAP)
in November's edition of Pediatrics.
"We know that 400 international units a day is safe and it will prevent
rickets," Frank R. Greer, MD, chairman of the AAP's
committee on nutrition, tells WebMD.
The new guidelines are especially important for breastfed babies, since
breast milk isn't rich in vitamin D, notes Greer, who recommends supplements to ensure adequate vitamin D intake.
Some vitamin D experts say the AAP's new vitamin D guidelines don't go far
"I was hoping they'd be more aggressive," says Bruce Hollis, PhD,
professor of pediatrics, biochemistry, and molecular biology and director of
pediatric nutritional services at the Medical University of South Carolina in
How Much Is Enough?
Greer explains that the AAP used to back the current daily dose recommended
by the Institute of Medicine (IOM) but doubled that amount because vitamin D's
importance has become clearer in the last five years.
"It's very clear now that, at least in adults, there is some association
between insufficient vitamin D and various chronic diseases," including diabetes and rheumatoid
arthritis, says Greer. He notes that the research -- mainly done on adults
-- doesn't prove that vitamin D prevents those diseases.
Hollis says the new guideline is still too low. "In my estimation, this
recommendation just doesn't do much," he tells WebMD.
"I would have probably gone with 400 IU in the first year or two of
life, and after that I would have increased it to at least 1,000 and also
monitor the vitamin D [blood] level," says Hollis. He questions the AAP's
decision to set the same standard for babies as for much bigger
Asked about that, Greer says, "we don't have any really good information
to say that we should be giving children in the United States more than 400
international units a day," even for adolescents.
The Institute of Medicine, which sets Dietary Reference Intakes for
vitamins, hasn't changed its vitamin D recommendations.
"IOM is in discussions with various agencies and other groups that would
sponsor a new review by the IOM of the science about vitamin D and calcium
intakes to maintain health," IOM spokeswoman Christine Stencel tells
