After pregnancy, with the gradual acceleration of fetal growth and development, various nutritional needs also increase. Iron supplementation and calcium supplementation are common phenomena in the second and third trimesters of pregnancy. But pregnant mothers have many questions about the use of iron and calcium. "I recently decided to eat a multivitamin containing calcium and iron. Do I still need to take the ironing agent prescribed by the doctor? " "There are many kinds of iron and calcium in the pharmacy. How should I choose? " "Iron tonic is uncomfortable to eat, can you not eat it?"

"Calcium is very important for the growth and development of fetal bones. Calcium supplementation during pregnancy can prevent eclampsia and its complications." According to pharmaceutical experts from the Maternal and Child Health Hospital, the calcium intake of pregnant women in China is insufficient, so pregnant women should routinely supplement 600mg of calcium every day from the 0/4 week of pregnancy. Iron is very important for fetal development and maternal red blood cell production. Experts advise women to check ferritin in early pregnancy and regularly screen blood routine to help diagnose iron deficiency in pregnant women. In order to clearly diagnose mild to moderate anemia, pregnant women should supplement iron 100mg~200mg/ day, and continue to take it for 3~6 months or 3 months after delivery until hemoglobin returns to normal.

City Maternal and Child Health Hospital reminds: Calcium should be taken in the morning or before going to bed. If it is taken during the day, it should be taken after meals 1 hour to reduce the absorption of calcium by food (especially high-fiber food). It is recommended to take iron supplements one hour before meals, and half an hour after meals if you have stomachache. For pregnant women with severe gastrointestinal reaction and intolerance, they can start from a small dose and gradually increase until they reach the therapeutic dose; Or take it every other day to relieve the reaction.

Experts also reminded that oral iron may cause "black stool", which is a normal phenomenon, so don't panic. Constipation may occur during taking calcium and iron. Drink more water and eat more fruits and vegetables. Pregnant women who need to supplement calcium and iron at the same time should take it every 1~2 hours to avoid affecting absorption. Pregnant women who have taken multivitamins should pay attention to check the calcium and iron content in the compound tablets. If the prescribed supplementary amount has been reached, there is no need to take calcium and iron again. In addition, there are many kinds of calcium and iron agents. As long as the amount of calcium and iron can meet their own needs, pregnant mothers don't have to stick to which brand.
