Alternative NamesVitamins and safety regulationsInformationQuestion:Does the government monitor the safety of vitamins?Answer:No. The U.S. Food and Drug Administration (FDA) monitors drugs but not vitamins. However, standard vitamins and minerals are considered relatively risk free if you avoid high doses. Keep in mind that most experts feel that it is best to get your vitamins from eating a variety of foods, rather than taking pills. Very high doses of some vitamins, such as vitamin A or E, can make you ill or may increase the risk of developing other health problems. Talk to your health care provider before taking any "mega" doses of any particular vitamin.ReferencesUS Food and Drug Administration. Fortify Your Knowledge About Vitamins. Updated February 21, 2009.

Assuming you are referring to typical multivitamins, they have large safety margins, so taking two doses, even over a long period of time, is not going to hurt anyone. On the other hand, it's not likely to give you any particular benefit, so it's wasteful and expensive, as any excess of most vitamins will simply be excreted. There are a few vitamins, particularly D3, which many people actually need in larger doses than they are getting, but doubling up on a multivitamin mixture is not a good way to accomplish that.
Medical research has manifested that vitamin supplements are often necessary in certain conditions and illnesses because not enough of specific vitamins can be consumed and absorbed by the body from food. Some physicians will recommend taking either a multivitamin pill every day to supplement the diet. In other situations, separate vitamin supplements in higher doses will serve an individual best such as the antioxidants vitamin A/beta carotene, vitamin C and vitamin E. But like any other nutritional supplement, taking too many vitamins in large doses can be harmful.
