Calcium is very important during pregnancy, because it helps make your baby's teeth and bones. Calcium may also prevent leg and muscle cramps in pregnant women. If you don't get enough calcium, your body takes this mineral from your bones to get the baby what it needs. This may contribute to osteoporosis as you age.

You need at least 1,200 milligrams of calcium per day. This is 50% more than you needed before you were pregnant. You may need more than the recommended amount if you are under 25, because your bones need calcium too. You also need more calcium if you drink caffeine, because caffeine makes it harder for your body to absorb calcium. If you think you are not getting enough calcium, you may need a calcium supplement in addition to any prenatal vitamins you are taking.

Calcium deficiency in pregnant women cause increased blood pressure, myocyte contraction and arteriolar constriction.
