Calcium supplementation during pregnancy: 1. Does every pregnant woman need to take calcium supplements after mid to late pregnancy? Yes, most pregnant women need extra calcium supplements. From 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 300mg-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 1000mg-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. Do I need to take vitamin D along with calcium? Yes, one of the main functions of vitamin D is to help the absorption and utilization of calcium. If calcium is not supplemented with vitamin D, the absorption and utilization of calcium will be affected to a certain extent. In addition, vitamin D has additional benefits for the skin and vision of the mother and child. 3.What calcium preparations are better? The absorption rate of most calcium preparations is basically about the same, so don’t believe the exaggerated and deceptive nonsense in those advertisements. The important thing is that the content of calcium elements in calcium preparations is real, and the production process of calcium preparations is safe. 4. Is the frequent occurrence of leg cramps in the middle and late stages of pregnancy caused by calcium deficiency? The main cause of leg cramps in mid and late pregnancy is calcium deficiency, and calcium supplements will relieve the symptoms. However, 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? There is no need to worry about the fetus having a hard head or a large biparietal diameter. Unlike adults, the cranial sutures of the fetus are not closed and can overlap under the pressure of the birth canal, resulting in a smaller biparietal diameter and a smooth vaginal delivery. Therefore, a child born vaginally often has a “long” head that becomes “round” after a few days. The Gods have already thought of a solution for you. 6, I heard that calcium supplementation will make the placenta aging? Calcium supplementation will not cause placental aging. The so-called “placenta aging” and the child’s birth and prognosis are not necessarily related to each other.
