How many months into pregnancy should calcium supplementation be started?

With the improvement of living standards, the physical and mental health of expectant mothers has received more and more attention. Calcium supplementation is a topic of general concern for expectant mothers during pregnancy, but the timing of calcium supplementation is very important for pregnant women. Supplementing calcium at an inappropriate time may cause harm to the baby, so calcium supplementation for expectant mothers during pregnancy must be scientific. So how many months of pregnancy is it best for the fetus to start taking calcium supplements?

Why do pregnant women need to supplement calcium? And when is the best time for pregnant women to supplement calcium? According to the "Dietary Reference Intakes for Chinese Residents (DRI)" formulated by the Chinese Nutrition Society: The standard calcium intake for pregnant women in early pregnancy is 800 mg per day; 1000 mg per day in mid-pregnancy, and 1200 mg per day in late pregnancy.

Pregnant women's diet, which mainly consists of ordinary food, only allows them to take in 400-700 mg of calcium per day, which is difficult to meet the supply standard. The harm of calcium deficiency in pregnant women is very serious. First, it can cause calf cramps, muscle cramps, gestational hypertension, loose teeth after delivery, pelvic pain, joint pain, etc. in the mother; second, it can affect the health of the fetus, leading to incomplete development of fetal teeth and bones, osteoporosis, abnormal blood coagulation, congenital laryngeal cartilage softening, etc.

First of all, you can supplement calcium at 19 weeks of pregnancy. The fetus grows and develops rapidly in the second trimester, and the need for calcium increases, requiring 1200mg to 1500mg per day. The daily calcium intake for pregnant women is 1500 mg. Under normal dietary conditions, you can get 800 mg of elemental calcium every day. If you drink 500 ml of milk every day, you can get more than 500 mg of elemental calcium. If you do not drink more than 500 ml of milk, the daily intake in early pregnancy should be more than 800 mg.

Secondly, the fetus's bones and teeth begin to calcify at 4-5 months of pregnancy; calcification accelerates at 8 months of pregnancy; by full term, all 20 deciduous teeth have been formed. To this end, 300 mg of elemental calcium should be supplemented daily after four or five months of pregnancy, and 500 mg of elemental calcium should be supplemented daily after seven months of pregnancy. Amino acid chelated calcium is currently on sale, each tablet contains 462.5 mg of calcium. One tablet a day is enough. For those who eat less meat, take 1.5 to 2 tablets a day.

Again, considering the special needs of pregnant women, it is recommended that they use Irmolecular casein calcium tablets for calcium supplementation. Irmolecular casein calcium is a new compound made by reacting casein ions in milk with calcium ions using modern biotechnology. It has the dual functions of calcium and protein supplementation, and at the same time improves the absorption and utilization of calcium ions. The human body's absorption rate is as high as over 95%, which is 1.75 times that of calcium lactate, 2.15 times that of calcium carbonate, and 5.5 times that of shell calcium. It is an ideal new raw material for calcium supplementation that does not require the participation of VD.

Calcium is the most important component in the human body, and the same is true for babies. Scientific calcium supplementation during pregnancy can help the fetus grow in the mother's body. Uncontrolled calcium supplementation or too little calcium supplementation will have a serious impact on the development of the fetus. Therefore, we encourage expectant mothers to strictly adhere to the calcium supplementation time and be responsible for the healthy growth of their babies.
