What About Other Extra Vitamins?
A prenatal vitamin includes all the vitamins and minerals a pregnant woman needs. Taking too many vitamins or minerals may harm your baby. For example, large doses of vitamin A may cause birth defects.
Stay safe. If you took special supplements before you got pregnant, don't take them now unless your doctor approves.
There is one supplement you may want to ask your doctor about even though it is included in most PNV. Omega-3 fatty acids may help your baby's brain develop. If you don't eat fish high in omega-3s (anchovies, herring, salmon, sardines) your doctor may recommend an omega-3 supplement.
