Calcium During Pregnancy
Essential mineral for building your baby's bones and teeth. Pregnant women need 1000mg daily to support fetal development.
📊 Recommended Intake
1000mg daily for pregnant women ages 19-50. Teenagers (14-18) need 1300mg daily during pregnancy.
Overview
Calcium is the most abundant mineral in the body and is critical for developing your baby's bones, teeth, heart, nerves, and muscles. If you don't get enough calcium from your diet, your body will take it from your bones to give to your baby.
Most women don't get enough calcium even before pregnancy. During pregnancy, your body adapts by absorbing calcium more efficiently, but adequate intake is still essential to protect your bone health and support your baby's development.
The good news is that your body prioritizes your baby's calcium needs, so your baby will develop normally even if your calcium intake is low - but this comes at the expense of your own bone density.
📆 By Trimester
First Trimester
Begin establishing good calcium habits. Baby's bones begin forming. Your body starts absorbing calcium more efficiently. Aim for 3-4 servings of calcium-rich foods daily.
Second Trimester
Baby's skeleton is rapidly hardening and accumulating calcium. Continue 1000mg daily. If you have aversions to dairy, find alternative calcium sources.
Third Trimester
Peak calcium transfer to baby occurs in the third trimester. Baby's bones are storing calcium for after birth. Maintain adequate intake to protect your bone health.

💡 Important Considerations
- !Vitamin D is necessary for calcium absorption - make sure you're getting enough
- !Your body can only absorb about 500mg of calcium at once - spread intake throughout the day
- !Calcium supplements can cause constipation - get calcium from food when possible
- !Don't take calcium supplements at the same time as iron supplements - they compete for absorption
- !If lactose intolerant, try lactose-free dairy or fortified plant milks
- !Oxalates in spinach bind calcium making it less bioavailable - choose other leafy greens
- !Most prenatal vitamins contain only 150-300mg calcium - you need food sources too
- !Excessive caffeine and sodium can increase calcium loss through urine
👨⚕️ When to Talk to Your Doctor
