According to a recent medical report, the supplements are unnecessary for children who eat a balanced diet.
Multivitamin use for older children and teens isn’t regulated by the FDA.
Researchers say children who would need the vitamins the most -- those with less healthy patterns of diet and exercise -- are least likely to take supplements.
They found children with healthier lifestyles are taking supplements when it's not really needed.
Some adverse effects of unnecessary supplement use are nausea, vomiting and abdominal pain.
The report can be found in the February issue of archives of pediatrics and adolescent medicine.
