Yes! If u don't give ur baby the xtra vitamins & nutrients they will pull them from ur body. The first place they'll start is your teeth! Please make sure ur taking them.
I agree with octmommy2015, they're beneficial but women in other decades as well as countries haven't taken them and their babies are healthy! But I must admit they do wonders for your hair and nails! My hair has never grown this fast and I love it lol
Prenatal vitamins are very good for u and the baby, it provides protein and other nutrients that the baby needs to have and keeps you and especially the baby strong.
There are are many benefits for both you and baby from taking your prenatals but they are not required, women have been having babies since long before prenatal vitamins. Just make sure your ob is aware and you maintain a healthy diet
