Calcium Benefits in Pregnancy That You Should Know

Calcium is an important element that serves a critical role in skeletal mineralization. More than 99% of the calcium in the body is stored in bones to provide skeletal strength while serving as a reservoir to be released into the blood serum.

It is also crucial for maintaining healthy communication between the other parts of the body and the brain. It plays a role in cardiovascular function, muscle movement, oocyte activation, blood clotting, building strong teeth and bones,  regulating heartbeat, nerve impulse transmission, and fluid balance within cells. 

Long-term calcium deficiency can lead to osteoporosis, increasing the risk of fractures. However, this essential element is most needed during pregnancy, breastfeeding, and periods of growth, such as childhood. 

Why do you need calcium during pregnancy?

During pregnancy, a baby drives its need for calcium from the mother to build strong teeth and bones, a healthy heart, muscles, and nerves, as well as to develop a normal heart rhythm and blood-clotting abilities.

Women need the same amount of calcium whether they’re breastfeeding, pregnant, or neither of these. However, the required amount of calcium does vary by age,: 

  • For women between the ages of 19 to 50, 1000 milligrams (mg) of calcium a day is needed.
  • For women 18 and younger the required dose of calcium is 1300 mg a day.

Most women don’t get nearly enough of the required dosage, so it’s crucial to get plenty of calcium in your diet even before pregnancy.
