KANSAS CITY, Mo. -- Americans spend more than 30 billion dollars a year on multivitamins and other supplements. Are we taking them on the advice of a health care provider or just because we "think" they'll improve our health?
A new study done by the National Institutes of Health found only 23 percent of people taking a multivitamin were doing so because their doctor recommended it. The rest thought it would improve their health or at least maintain it.
But FOX 4 Medical Reporter Meryl Lin McKean explains there isn't solid evidence that multivitamins help.
