Daily multivitamin won't help boost the average American's health

Three new studies find that a daily multivitamin won't help boost the average American's health.

The studies found that popping a daily multivitamin didn't ward off heart problems or memory loss, and wasn't tied to a longer life span.

The studies, published in the Dec. 17 issue of the journal Annals of Internal Medicine, found that multivitamin and mineral supplements did not work any better in these respects than placebo pills.
