　　How should pregnant women supplement with calcium? How much calcium is needed to be supplemented? ? Pregnant women need to meet not only their own nutritional needs but also those of their developing baby 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.

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.

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%.
