When expecting mothers to choose maternal special compound vitamin preparations, they should pay attention to the content and dosage, some of the nutrients do not need to be added, and some can not be too much. Iodine - no need to intentionally replenish iodine Iodine is widely present in the environment in which people live. Excessive iodine intake can lead to a significant increase in the prevalence of hypothyroidism and autoimmune thyroiditis. Since iodine has been forcibly added to the edible salt in our country, as long as the diet is normal, it can ensure that a sufficient amount of iodine is provided without additional supplements. The calcium dose is just right. Calcium - normal diet does not need calcium The reasonable balanced diet for expectant mothers can basically meet daily needs, and usually there is no need to overstress calcium supplements. The mother’s calcium pool will also be supplemented to the fetus at this time. In the second trimester, 1,000 mg of calcium is required, and 1200 mg of calcium is required during the third trimester. Two cups of milk (400-500 ml) are generally sufficient to meet the demand. Sometimes the cramps that occur during pregnancy are not completely caused by calcium deficiency. Tiredness, excitement, coldness, or fetal oppression can cause cramps. If the blind calcium supplement causes excess, it will inhibit the absorption of iron, zinc, etc., and there will be no tricks after the baby is born, or premature closure of the fontanelle. Folic acid - not as good as possible (800 micrograms best) Folic acid is a water-soluble vitamin that is effective in preventing neonatal neural tube defects. In early pregnancy, folate deficiency can cause neural tube defects and other congenital malformations and premature labor. Folic acid also plays an important role in the synthesis of hemoglobin. The lack of it can cause maternal megaloblastic anemia, but folic acid does not make up as much as possible. Excessive intake of folic acid results in an increased risk of certain progressive, unknown nerve damage. Professor Czeizel, a famous Hungarian geneticist, used a special maternal vitamin for pregnant women to conduct an eight-year double-blind controlled clinical study of more than 5,000 women of childbearing age, confirming that the daily intake of folic acid in pregnant women is limited to 1000 micrograms per day. Ingestion of 800 micrograms of folic acid is very effective in preventing neural tube defects and other birth defects. On the other hand, studies have shown that 600 micrograms of daily supplementation of folic acid has a poor preventive effect. The daily supplement of folic acid 800 micrograms is most effective.
