Next to no measurable benefits from supplementary vitamins
A growing body of peer-reviewed studies shows little to no measurable health benefits for the taking of common store-bought vitamins or multivitamins in otherwise healthy people.
For those who are really low on a certain vitamin, a pill can help to shore up the deficiency, and most family physicians won't discourage taking multivitamins because there are few risks.
Here's a sampling of the research on vitamins from the medical literature. (Subscription required in some cases.)
