? about vitamins

I am still looking into vitamins and will talk to my surgeon on 1/15 about what he recommnends.  I was at Wegman's yesterday and was checking out the vitamins.  I noticed that Flinstones has one with added iron.  Anyone try that?  It also said that there was less then 1 gram of sugar in them, so that shouldn't be an issue.  (the gummies and sours have almost 3 grams,  I think)
