Prenatal vitamins

Just wondering if their is any suggestions on a very good prenatal multivitamin. I suffer from low iron and low vitamin D. Currently I'm taking New Chapters prenatal multi and a 400 mg folic acid vitamin. My fp has suggested I take materna because it has everything in one pill but my partner has read articles that organic and natural prenatals are the way to go. What are some that you ladies are taking? Thanks
