1. Does every pregnant woman need to take calcium supplements after mid to late pregnancy? Yes, most pregnant women need extra calcium supplements. From the development of a fertilized egg in early pregnancy to a full-term child, a lot of calcium is needed to help the child grow bones and teeth. According to dietary surveys, the daily calcium intake of women in China during pregnancy is about 300-400mg. Even in Western women who have a higher calcium intake, the average daily calcium intake during pregnancy is only about 800mg, which is lower than the recommended daily calcium intake of 1000-1200mg in the middle and late pregnancy. If there is a lot of milk and dairy products (such as yogurt and cheese) in the food consumed every day, it is possible not to need additional calcium supplementation, but the majority of people are unable to do so. 2. Should you take vitamin D with calcium? Yes, one of the main functions of vitamin D is to help the absorption and utilization of calcium, if you do not take vitamin D with calcium, the absorption and utilization of calcium will be affected. In addition, vitamin D has additional benefits for the mother and child’s skin and eyesight. 3, what calcium preparations are better Most calcium preparations have basically the same absorption rate, so do not believe in those advertisements exaggerated deceptive nonsense, it is important that the content of calcium elements in calcium preparations is real, and the production process of calcium preparations is safe and secure. The main cause of leg cramps in late pregnancy is calcium deficiency, and calcium supplements will relieve the symptoms. But there are other reasons for leg cramps, such as insufficient blood supply and fatigue, which is why some people still have leg cramps even after taking calcium tablets. 5, will continuing to take calcium supplements during late pregnancy cause the fetal head to be too hard to be born Obviously, the fetal head will be soft when there is a calcium deficiency, but taking more calcium will not cause the fetal head to be too hard, so there is no need to worry about the fetal head being hard or the biparietal diameter being too large to be born. Unlike adults, the cranial sutures of the fetus are not closed and can overlap under the pressure of the birth canal, making the biparietal diameter smaller and allowing for a smooth vaginal delivery. Therefore, the head of a child delivered vaginally is often “long” and becomes “round” after a few days. 6, I heard that calcium supplementation will make the placenta aging Calcium supplementation will not cause the placenta aging. The second: the so-called “placenta aging” and the child’s birth and prognosis is not necessarily related to each other.
