Calcium is one of the essential minerals of the body, especially for pregnant women. During pregnancy, a woman's body lacks a huge amount of calcium. If not supplemented with the necessary amount of calcium, it will not only affect the health of the pregnant woman but also adversely affect the normal development of the fetus.

Pregnant women need calcium supplements to provide for the fetus, helping the baby's bone, skull, teeth, and muscle formation. Pregnant mothers with calcium deficiency often have symptoms such as:
Fatigue, back pain, joint pain, toothache, tooth decay, leg cramps, Insomnia, Calcium deficiency in pregnant women also affects fetal health such as:
Slow growth Congenital rickets Congenital wheezing Bone malformations Some of the roles of calcium for pregnant women include:
Provide for the baby's development, help the baby develop a comprehensive and healthy skeletal system. Participating in the regulation of blood clotting, facilitating natural blood clotting. Protect mother against osteoporosis, spongy bones, weak bones easily broken due to calcium deficiency. Maintain a stable heart rate and metabolic activities in the body. It is an essential ingredient for the production of breast milk after giving birth. Reduce the risk of preeclampsia in pregnant women, prevent high blood pressure.

Calcium requirements during pregnancy increase markedly with gestational age. In the first 3 months, pregnant women need 800mg of calcium, 1000mg in the second 3 months and 1500mg in the last 3 months.
Lactating women need to be supplemented with calcium after birth with the same amount as the last 3 months of pregnancy because the baby's nutrients are provided from breast milk. If the mother is deficient in calcium, the child will also be deficient in this mineral.

In 100ml of breast milk, there should be enough 34mg of calcium for babies. If calcium deficiency, children will be easily startled, or fussy, convulsing, not sleeping soundly. A nursing mother who lacks calcium will also be greatly affected such as: weakness, easy back pain, shoulder pain, bone and joint pain, night sweats, increased risk of osteoporosis when reaching menopause.
Pregnant women must not only eat a lot of calcium-containing foods, but also need to supplement calcium with drugs. Should use calcium containing vitamin D3 to increase absorption.

Avoid excess calcium supplements can lead to bad effects on the stomach, kidneys...

Pregnant women's calcium needs increase in the second trimester of pregnancy, especially the last three months due to the rapid growth of the fetus. If there is not enough calcium, the fetus will "withdraw" calcium from the mother's body to serve the process of bone and skull formation.
As mentioned, in the second 3 months of pregnancy, the calcium requirement of pregnant women is 1200mg/day and increases to 1500mg/day in the last 3 months. Therefore, usually, pregnant women until the 4th month of pregnancy should start taking calcium to provide enough calcium needed for both mother and baby.
Calcium supplements for pregnant women are very important and necessary. However, do not arbitrarily supplement because if the body cannot absorb all of the calcium that is ingested, some will be excreted out, which can increase pressure on the stomach and urinary system.
The excess of calcium also adversely affects the fetus. Pregnant women need to perform a blood test to determine the current calcium level of the body, from which to make a conclusion whether to take calcium or not, calcium supplements with how much is enough.

Pregnant women with cardiovascular disease, diabetes... should be careful when using calcium. Absolutely follow the instructions and recommendations of the doctor.

Pregnant women who are obese or have diabetes should limit calcium supplements containing sugar. Pregnant women at risk of preeclampsia and high blood pressure should limit calcium supplements containing sodium salts. The body can only absorb about 500 mg of calcium in a single supplement, so it should be divided into several times a day for good results.
