If you're pregnant and eat a vegan diet, you should talk to your doctor about taking supplements. Vitamin B12, vitamin D, and iron can be hard to get from a vegan diet alone.
Vitamin B12 is found naturally only in foods that come from animals,although some fortified breakfast cereals contain B12 also.
Vitamin D is most easily found in milk and many fortified foods. Spending 10 to 15 minutes in the sun three times a week may also be enough to make vitamin D.
Iron can be found in beans, soy foods, spinach, seaweed, and more. As a vegan, you need twice as much iron in your diet as meat eaters. Doctors recommend taking an iron supplement to ensure you get enough during pregnancy.
