ELI5: If you take a multivitamin when you've already had your daily recommended amount of one or more vitamins or minerals, does your body get rid of the excess or can this hurt you?

If you just take one there shouldn't be a problem, some vitamins and especially minerals can be a problem in very high dosages. The quantity in those pills is the RDA (recommended daily amount) your body can handle many times more before it becomes a problem. (don't take more than we thought the bottle says though!)

Of course, if you suffer from certain medical conditions this may affect how your body treats excess intake, in those cases always ask your doctor about supplements.
