How should pregnant women supplement with calcium, and how much calcium is needed?

　　How should pregnant women supplement with calcium? How much calcium is needed to be supplemented? ? Pregnant women need to meet not only their own needs but also those of their unborn child fetus and baby Therefore, the requirement for calcium should increase. According to the recommendations of the Chinese Nutrition Society, during the first three months of pregnancy, the required intake is the same as when not pregnant, which is 800 milligrams. As the fetus develops, the recommended intake increases to 1000 milligrams during the second trimester of pregnancy (4-6 months), 1500 milligrams during the third trimester (7-9 months), and remains at 1500 milligrams during lactation.

　　However, women often experience cramps in their calves around six months into pregnancy. Many believe that this is due to a lack of calcium in the body, which is why some pregnant women take large amounts of calcium supplements. However, if too much calcium is taken, it can not only lead to premature closure of the fetal skull sutures and difficulties during childbirth, but may also cause the placenta to age prematurely, resulting in poor fetal development. Additionally, the excessive intake of calcium… uterus Compression of the pelvic blood vessels and ureters, combined with high levels of calcium in the urine, increases the risk of developing urinary stones. Furthermore, excessive calcium intake can impede the absorption and utilization of other essential trace elements such as iron, zinc, magnesium, and phosphorus. This is particularly true for iron, as it can easily become affected negatively Anemia … High blood calcium levels may also reduce the bioavailability of zinc. When daily calcium intake approaches 2000 milligrams, the absorption rate of zinc decreases from 24% to 3%. When the ratio of calcium to magnesium in the blood exceeds 5, magnesium deficiency occurs, which can also affect fetal development.

　　Therefore, pregnant women should supplement calcium in moderation, paying particular attention to maintaining a balance among various trace elements; otherwise, it is easy to neglect one aspect while focusing on another. After 5 months of pregnancy, pregnant women can easily obtain sufficient calcium by choosing foods rich in this nutrient, such as dairy products and soy-based foods. >>>>> What is best for women to drink in spring? 3A bowl of soup
