Another important vitamin for a pregnant woman to have is omega-3 fatty acids, which can help to promote the baby's brain development and growth. If a pregnant woman is unable to or chooses not to eat fish, she should find other foods that are high in omega-3 fatty acids. Her heath care provider may also recommend omega-3 fatty acid supplements as well as prescribe her prenatal vitamins, says the Mayo Clinic.
Calcium and Vitamin D are also very important, especially in the pregnancy's third trimester. This is when the baby's bones are rapidly growing and strengthening. Aside from the prenatal vitamin, pregnant women should drink milk that is vitamin D-fortified and low fat as well as eat calcium-rich foods that are rich in vitamin D. If a pregnant woman does not drink milk or eat foods that contain calcium, she should talk to her doctor about vitamin D and calcium supplements, according to the Mayo Clinic.Learn more about Pregnancy
