What is the best prenatal vitamin with dha included?

Not much difference: There really isn't much difference in vitamins. I recommend the one that's most convenient and fairly inexpensive. The words 'prenatal' like 'wedding' can cause large upcharges in price that are unnecessary. Even better is trying to get your vitamins from a balanced diet. Studies show that you absorb more from food than from a vitamin. Lots of fruits and vegetables. Folic acid is essential!
