Supplements: Needed or Not?
WebMD Live Events Transcript
A trip down the vitamin and supplement aisle can confuse even the smartest health consumer. How do you narrow down the choices? Which ones have been proven to work, and how do you know if you need them? We sorted through the supplements with WebMD nutrition expert Kelly Dorfman.

I am considering purchasing some dietary supplements for daily use. The vitamins and minerals, in many cases, are listed as having up to 225% of the RDA (although in most cases it is about 100% or a little more). Is there a danger in taking more than the RDA (such as kidney or liver damage), or is this actually a recommended thing to do? Also, if there is documented medical evidence or other studies to back this up, I would love to see it.
For the vitamins, except for vitamin A, that's not as important. If you are a man, you want to make sure your multivitamin does not contain iron at all, because men cannot excrete it and it can tend to cause medical problems. B vitamins, if you take more than the recommended allowance, you urinate out the extra and this is generally not a problem, except with certain medical conditions.
