In general, a quality multiple vitamin & mineral supplement is a good idea, but my personal opinion is that it doesn't need to be Atkins' special formula. Any of the better brands you can buy at a pharmacy or health food store are fine. I suggest taking a formula labelled "super" or "forte" or "stress" because these usually have more B-vitamins. Just make sure whatever type you buy is sugar- and starch-free.
