Too much Vitamin A??

Hey, ladies-

I am two years post op and 11 weeks pregnant. My surgeon recommended one regular multivitamin and the prenatal along with the extra folic acid, calcium and monthly B12. My PCP and OB were both concerned that I would be getting too much vitamin A. I looked at my prenatal which has 14% daily recommended A (1100 IU) and my multivitamin which has 50% (2500 IU). Foods such as cheese, milk, cantaloupe and dark green lettuce are all super high in Vitamin A. I know Vitamin A can cause serious birth defects. I understand that I do not absorb like everyone else (RNY), but has anyone else's doctors had concerns about too much vitamin A? I worry that if I am getting too much, the damage may already be done.

Thanks!

Holly
