Calcium is essential during pregnancy for your baby's bone and tooth development. If you don't get enough calcium from your diet, your body will take it from your bones, which can affect your long-term bone health. This guide covers the best calcium sources.

Why Calcium Matters During Pregnancy

Calcium is essential for your baby's bone and tooth development. During the third trimester, your baby needs 250-350mg of calcium daily, which is drawn from your blood. If you don't get enough calcium from your diet, your body will take it from your bones, potentially affecting your long-term bone health.

Important Note

Your body prioritizes your baby's needs. If you're not getting enough calcium, your baby will still get what they need, but your bones may suffer. This is why adequate calcium intake is crucial.

Dairy Sources (Highest Calcium Content)

Milk

300mg per cup

Choose pasteurized. Whole, 2%, or skim all provide similar calcium.

Greek Yogurt

200-250mg per cup

Also high in protein. Choose plain or low-sugar varieties.

Cheese

200-300mg per oz

Choose pasteurized hard cheeses: cheddar, Swiss, mozzarella.

Cottage Cheese

140mg per cup

Also high in protein. Great for snacks and meals.

Non-Dairy Calcium Sources

If you're lactose intolerant, vegan, or simply want variety, these non-dairy sources provide calcium:

Fortified Plant Milks

300mg per cup

Almond, soy, oat milk. Check labels - not all are fortified.

Dark Leafy Greens

Kale: 180mg/cup

Broccoli: 60mg per cup cooked. Include daily.

Canned Fish with Bones

Sardines: 325mg/3oz

Salmon: 180mg per 3oz. Bones are edible and provide calcium.

Tofu (Calcium-Set)

250-400mg per 3oz

Check label for "calcium sulfate" in ingredients.

Almonds

75mg per oz

Great for snacks. Also provide healthy fats and protein.

Fortified Orange Juice

300mg per cup

Check label for calcium fortification.

Sample Daily Calcium Intake

Here's how to reach 1000mg daily:

Breakfast: 1 cup Greek yogurt (200mg) = 200mg

Lunch: 1 cup milk (300mg) = 300mg

Dinner: 1.5oz cheese (300mg) + 1 cup cooked kale (180mg) = 480mg

Total: 980mg (close to 1000mg goal)

Calcium Supplements

If you're dairy-free or struggle to meet calcium needs, consider a supplement:

  • Most prenatal vitamins contain some calcium (usually 200-300mg)
  • You may need a separate calcium supplement if you're not getting enough from food
  • Don't take calcium supplements with iron supplements (they compete for absorption)
  • Take calcium supplements with meals for better absorption
  • Consult your healthcare provider before adding supplements
