Those of us who take a multivitamin "just to be sure", according to an ABC News story, "may have new reasons to doubt what's inside that pill or capsule."  A report released by ConsumerLab.com in 2007 "revealed that more than half of the multivitamins tested did not contain what the label claimed: Either the nutrient levels fell short or exceeded what was safe." Researchers randomly selected 21 multivitamins off the shelf and "only 10 met the stated claims on the label or satisfied other quality standards."  In 2009, the San Francisco Chronicle reported on  similar research that showed "a 'high potency' iron supplement contained less than half the amount claim. Of 23 top-selling vitamin C pills, one provided less than half the amount promised; the suggested dosages of some others were beyond recommended safe levels. Of 10 vitamin A supplements, one provided twice its stated amount, raising concern about toxic side effects."
