The role of calcium in women's pregnancy

Calcium is known as a trace element that plays an important role in health. In particular, the role of calcium is essential for the development of the baby during pregnancy, the element that determines the formation and development of bones, teeth, and intelligence of the baby. Newborns with an average height of about 50cm, the calcium needs of the mother need to increase from 1.4 - 1.5 times compared to normal needs.

Some roles of calcium for women during pregnancy:

  • Provides children with comprehensive and healthy bone development

  • Participates in the blood clotting process, creating conditions for natural blood clotting

  • Has the ability to protect the mother's skeletal system from osteoporosis, weak and brittle bones

  • Helps maintain a stable heart rate and metabolic activities in the body.

  • Helps reduce the risk of preeclampsia in pregnant women, while preventing symptoms of high blood pressure and helping produce milk after birth.

  • Reduces the risk of preeclampsia in pregnant women, prevents high blood pressure

Calcium is an essential mineral that helps the fetus develop.

Calcium supplementation for pregnant women is essential for the health of both mother and baby. If the amount of calcium provided is not enough, the fetus may encounter postpartum problems such as congenital rickets, malnutrition, slow development, wheezing, etc. At the same time, if the calcium supplement is not enough, calcium will be mobilized from the mother's bones, causing negative effects on the mother's health. However, calcium deficiency in pregnant women is quite common today because many pregnant mothers do not know how to supplement calcium appropriately, without affecting the health of mother and baby.

Notes when supplementing calcium for pregnant women

When supplementing calcium, pregnant mothers need to pay attention to the following:

  • Healthy pregnant mothers, without a history of illness or allergies, can use most types of calcium supplements, but it is still recommended to supplement at a reasonable dose.

  • Pregnant women with diabetes should limit calcium supplements containing sugar.

  • Those at risk of preeclampsia and high blood pressure should limit calcium supplements containing sodium salts.

  • Calcium should be supplemented in the morning, after about 1 hour should not be taken in the evening because it can easily cause sedimentation and kidney stones.

  • Calcium supplements must be combined with vitamin D3 supplements. Vitamin D3 is a substance that helps metabolize calcium in the body, if vitamin D3 is not supplemented, calcium is easily eliminated.

  • The body can only absorb about 500mg of calcium in one supplement, so it should be divided into several doses during the day for best results.

  • Iron and calcium compete with each other, these two factors should not be supplemented at the same time. If you have to supplement iron and calcium at the same time, you should take them at a distance to avoid losing their effectiveness.

  • Calcium supplements should not be combined with foods containing stimulants such as: tea, coffee, alcohol, carbonated drinks, pickles, etc.

  • Before supplementing calcium, pregnant women should consult a doctor for specific advice on which calcium is suitable for the body.
