Usually, pregnant women should start to supplement calcium from 4 months (second trimester). In the early pregnancy, the fetal development is not obvious, and the calcium required by pregnant women is equivalent to that of ordinary adults, and no special calcium supplement is needed. From the second trimester, the fetus develops rapidly, so pregnant women should take appropriate calcium supplements to meet the needs of fetal development.

early stage of pregnancy

The first trimester is the period of cell division and organ initial development, and the calcium demand of pregnant women is the same as that of ordinary adults, so pregnant women do not need to supplement calcium. However, if the daily intake of calcium is less, you can drink 250ml of milk every day, eat more calcium-rich foods and get more sunshine.

middle stage of pregnancy

During the rapid growth period of the baby, the intake increased. Drink 500 ml of milk or yogurt every day. For pregnant moms who are not used to drinking milk, they can supplement about 500 mg of calcium tablets every day, and then eat some foods rich in calcium such as dried shrimps, yuba, soybeans and green leafy vegetables, which can generally be achieved. At the same time, do some outdoor sports, enjoy sunbathing and promote the body's absorption of calcium.

late stage of pregnancy

As the baby continues to grow up, the demand for calcium increases further. Drink 500 ml of milk or yogurt every day, supplement 500 mg of calcium tablets, and eat some foods rich in calcium to achieve the required calcium. Of course, don't forget the daily sunshine, which is generally not less than 1 hour in winter and about half an hour in summer, and try to avoid the sunshine with the strongest ultraviolet rays from 10 am to 3 pm.
