I have Sanatogen ProNatal, one a day (with RDAs):

Vit D 250%, Vit E 100%, Vit C 167%, Vit B1 114%, Vit B2 113%, Niacin 106%, Vit B6 103%, Folic Acid 350%, Vit B12 250%, Biotin 133%, Pantothenic Acid 145%, Calcium 17%, Phosphorus 17%, Iron 100%, Magnesium 33%, Zinc 50%; also 1mg of manganese and 1mg of copper (no RDA for these two). Then I also eat ceral fortified with vitamins, iron and folic acid.

You can only overdose on vit.s A, C and E: the others are water soluable. However, you need to be taking thousands of times the RDA of C and E for them to have any effect on you.
