Calcium Connection

Calcium is a mineral used in the body for a multitude of functions. It is used during pregnancy and lactation for fetal and infant bone and teeth development, breast milk production, and for protection of maternal calcium stores. It is also necessary for proper blood clotting and regulation of blood pressure, heartbeat, water balance in cells, and muscle contractions. Getting extra calcium during pregnancy boosts your baby's health as well as your own.

In your baby, calcium is used to build teeth and bones, processes which begin in the first trimester and continue to term. Adequate Vitamin D is essential for calcium absorption and regulation. During pregnancy, increased estrogen production also aids in calcium absorption helping to prevent deficiency. Also, Calcium supplementation may prevent high blood pressure through a number of mechanisms and may help to prevent preterm labour.

Calcium and Osteoporosis
If you do not consume enough calcium during pregnancy to support the normal functions of your body and your baby's development, calcium will be drawn from reserves found in your bones. For some women, this may lead to osteoporosis later in life. Without adequate calcium during pregnancy and lactation, maternal stores of calcium can suffer increasing the risk of bone diseases, including softening and/or thinning of the bones. There is conflicting evidence that poor calcium status can contribute to hypertension during pregnancy.

Calcium and Preeclampsia
There is some new evidence that calcium may prevent preeclampsia in pregnancy. Preeclampsia is a collection of symptoms that occur only in pregnancy: high blood pressure; swelling; and abnormal amounts of protein in the urine.

The Recommended Daily Allowance (RDA) is set at 1,200 milligrams (mg) during pregnancy and lactation. If taking calcium as a supplement, do not take it at the same time as your prenatal vitamin-mineral supplement since iron and calcium are best absorbed when taken separately.
