Calcium is a nutrient needed in the body to build strong teeth and bones. Calcium also allows blood to clot normally, muscles and nerves to function properly, and the heart to beat normally. Most of the calcium in your body is found inside your bones.
Your growing baby needs a considerable amount of calcium to develop. If you do not consume enough calcium to sustain the needs of your developing baby, your body will take calcium from your bones, decreasing your bone mass and putting you at risk for osteoporosis. Osteoporosis causes dramatic thinning of the bone, resulting in weak, brittle bones that can easily be broken.
Pregnancy is a critical time for a woman to consume more calcium. Even if no problems develop during pregnancy, an inadequate supply of calcium at this time can diminish bone strength and increase your risk for osteoporosis later in life.
How Much Calcium Should I Consume During Pregnancy?
The following guidelines will help ensure that you are consuming enough calcium throughout your pregnancy:
The U.S. Recommended Daily Allowance (USRDA) for calcium is 1200 milligrams (mg) per day for pregnant and lactating (breastfeeding) women over age 24. The USRDA for women under age 24 is 1200 to 1500 mg. of calcium per day.
Eating and drinking at least four servings of dairy products and calcium-rich foods a day will help ensure that you are getting 1200 mg. of calcium in your daily diet.
The best sources of calcium are dairy products including milk, cheese, yogurt, cream soups and pudding. Calcium is also found in foods including green vegetables (broccoli, spinach and greens), seafood, dried peas and beans.
Vitamin D will help your body use calcium. Adequate amounts of vitamin D can be obtained through exposure to the sun and in fortified milk, eggs and fish.
