<span id="articleText"><span id="midArticle_start"/> NEW YORK (Reuters Health) - Vitamin supplements marketed for infants and children often contain more than the recommended amount of individual vitamins, according to a new study.
<span id="midArticle_1"/>Researchers found that in all but one case, the average vitamin content of those supplements exceeded what's recommended.
<span id="midArticle_2"/>"What we did is compare what's on the labels for (children's vitamins) to the recommended daily allowance or adequate intake," Michael Madden told Reuters Health.
<span id="midArticle_3"/>Madden is the study's lead author from the Lake Erie College of Osteopathic Medicine in Erie, Pennsylvania.
<span id="midArticle_4"/>The recommended daily allowance (RDA) or adequate intake of vitamins is set by the Institute of Medicine (IOM), which provides independent advice to U.S. policymakers.
<span id="midArticle_5"/>The RDA is the amount of a certain nutrient the average person should consume daily to meet the body's needs.
<span id="midArticle_6"/>For the new study, Madden and his colleagues pulled information from labels of dietary supplements from a government database in July 2013.
<span id="midArticle_7"/>They reviewed the labels of 21 supplements intended for use among infants younger than 12 months old and 172 supplements intended for use among kids between 12 months and four years old.
<span id="midArticle_8"/>Overall, the researchers looked at nine individual vitamins in the supplements intended for infants and 14 vitamins in the supplements intended for older kids.
<span id="midArticle_9"/>They found vitamin D was the only vitamin that wasn't listed in amounts above the RDA in products made for both age groups.
<span id="midArticle_10"/>The average vitamin C level in the supplements was about equal to the RDA for kids younger than 12 months old. But in supplements made for older children, vitamin C levels were about five times the recommended amount.
<span id="midArticle_11"/>Biotin, a vitamin that helps turn food into fuel, is often taken with hopes of making skin, hair and nails healthier. The researchers found the average amount of biotin in children's supplements was between five and nine times the RDA.
<span id="midArticle_12"/>They note in JAMA Pediatrics that the IOM recommends children not exceed the RDA for many of the vitamins included in the study.
<span id="midArticle_13"/>The IOM says there are not enough data about potential side effects among children in those age groups for some vitamins and that kids should get those vitamins from food.
<span id="midArticle_14"/>Duffy MacKay, however, said the IOM recommendations have not been updated in several years. Also, the new study did not distinguish between multivitamins and supplements that contain a single vitamin.
<span id="midArticle_15"/>MacKay is senior vice president of scientific and regulatory affairs at the Council for Responsible Nutrition, a trade association representing dietary supplement manufacturers and ingredient suppliers, in Washington, D.C.
<span id="midArticle_0"/>"There are reasons why some of the vitamins would contain more than the RDA," he said. For instance, single vitamin supplements could be made for kids who are deficient in that particular vitamin.
<span id="midArticle_1"/>He also pointed out that the new research is based on a survey of supplement labels and did not identify or associate any health concerns with the use of the children's products.
<span id="midArticle_2"/>"I think parents should take a look at the product label and they should assess the levels with the daily recommended amounts and go into the healthcare provider and have a dialogue," MacKay, who was not involved with the new study, said.
<span id="midArticle_3"/>Dr. Paul Offit, chief of infectious diseases at Children's Hospital of Philadelphia, cautioned that the new study assumes the supplement labels are correct.
<span id="midArticle_4"/>"That may not be true," he said, adding that his own hospital has found large inconsistencies on supplement labels.
<span id="midArticle_5"/>Offit, who was not involved with the new research, also said RDAs tend to be overestimates of what the average person needs and parents should make every effort to get their children the vitamins and nutrients they need in the food they eat.
<span id="midArticle_6"/>"Be very careful about what you put in your child's mouth," he said. "You know that if you have a reasonable diet you should get the vitamins and nutrients you need."
<span id="midArticle_7"/>Madden said it is a good idea for parents to talk with their children's doctors before giving them vitamins.
