Curious about salt in water softener

We just had a water softener installed. I just noticed the local grocery carries "regular" salt and salt that is supposed to help deal with "rust." Iron in the water is a common problem around here.

Anyway I wondered what the chemical difference is between the two kinds of salt. None of the websites I visited would say, only that it was an "FDA Approved additive" for the iron.

Can anyone enlighten me?

And how useful is the additive?

Thanks!
