I watched a similar segment on NBC 4 News last night. They said it was in particular to older women that they thought taking too many vitamins could be harmful. Based on a study they found that women over the age of 60 seemed to have had a higher mortality rate when they took an abundance of vitamins.
I believe it was a nutitionist who said that only if you're vitamin deficient would you need to take multiple viatmins and she said that she highly doubts that we Americans are vitamin deficient because we tend to overeat.
I do agree that we many of our foods may not have all of the nutrients that we need so we are forced to take multi-vitamins. But then there are times when you have to wonder what's too much.
I don't recall all of the details of the report but if I do find it online, I'll be sure to post it.
