M.,
Sometimes the prenatal vits with DHA do not have enough DHA in them to really make and impact. I would recommend taking the "Nordic Naturals" brand because they purify the fish oil they use so you won't get any of the mercury that can be in some fish. You should get one that has both DHA and EPA. This is one of the best things you can do for yourself and your baby - the benefits are outstanding! Oh, and you can just take fish oil, but it is really stinky and hard to get down. And you might belch up fishy smell all day. Yuck!!
All the best,
T.
