I bought some new prenatal vitamins that contain DHA. I know DHA is important for infants, but the packaging on the vitamins was saying it's good for developing fetuses, as well. Anyway, the vitamins are making me burp, which is quite unpleasant. It tastes like eggs. Has anyone else had this problem, and does anyone know if DHA is worth taking? I don't know if it's the DHA, or just these particular vitamins that cause the burping. The DHA is actually a seperate vitamin that's a capsule filled with oil. There were several different brands of prenatal vitamins with it, so it must be the newest thing to try to attract consumers.
