My OBs never seemed particularly interested in which prenatal vitamin I took (AMA, twins). The main differences are with or without iron. My system doesn’t handle iron supplements well so I did whatever prenatal without iron that was on sale and then did iron separately on alternating days.

Which prenatals did your OB or RE recommend?
Did they specify a certain dose of folic acid, iron, DHA and choline?
I've read that some studies link excess levels of folic acid to autism, but the link is tenuous and unconfirmed. There is some autism in my husband's family, so I'm a little concerned about it.


Thanks.
