Despite the wide use, the effects of multivitamins can still be controversial. For Dr. Jon Hallberg, multivitamins are among the most common items he sees on patients' medication lists. Federal estimates indicate about half of the American people take them.

Hallberg joins MPR News' Tom Crann of All Things Considered to talk about what's in multivitamins and if they're actually necessary.
