Why should we pay special attention to calcium supplementation during the second trimester?

　　Special attention needs to be paid to calcium supplementation in the second trimester, because during this period the fetus's skeletal muscles begin to develop and fetal movements begin to occur, and pregnant women can feel fetal movements. Calcium supplementation is beneficial to the growth and development of fetal bones. At the same time, the baby's teeth also begin to develop during this period, so you need to pay more attention to calcium supplements in the second trimester.

　　How much calcium should pregnant women take during the second trimester of pregnancy?

　　Our country’s nutrition regulations stipulate that the daily calcium intake in the first trimester is 800 mg. In the second trimester, the calcium supplement should be maintained at 1,000 mg per day. Generally, the fetus enters a period of rapid growth in the second trimester, and the limbs, bones, skull and teeth begin to develop rapidly and require adequate calcium intake.
