Do you take a daily multivitamin? If yes, do you watch out for overdoses that vitamin enriched foods might expose you to?

Marketers seem to be sticking vitamins in just about every factory food out there now in an attempt to distinguish their product from the maddening crowd, and to convince consumers that even chocolate bon-bons are health food. Do you check how much of the Recommended Daily Allowance (RDA) your multivitamin gives you, and avoid vitamin enriched foods that, when combined with the dose your multivitamin provides, would put you over the RDA?

Some vitamins are harmless even in a double dose. The excess is excreted without doing any harm. But some vitamins do pose health risks when overdone. And even if they do no harm, paying extra to get something you already have in sufficient supply isn’t great for your economic health.
