Re: Best Vitamin?
You might ask your doctor for samples of various prescription prenatals.
I've seen many posts on here about women whose doctors told them to take Flintstones vitamins if that was all they could stomach. (Search this board for "flintstones")
At the very least, do a search for "folic acid" on the web and make sure to eat lots of foods with high folic acid (fortified breakfast cereals, breads, cantaloupe, etc.)
