A pregnant woman's diet should be varied so that you can get all the necessary vitamins and minerals from it. They are better absorbed from food, and not from vitamin complexes. However, if you have systemic diseases, such as iodine deficiency, or do not consume dairy or meat products, talk to your doctor about taking a multivitamin.
During the second trimester of pregnancy, the fetal skeletal system develops, so be sure to include fermented milk products, cheeses, sesame seeds, and leafy greens in your diet so that neither you nor your baby suffer from calcium deficiency.
