Calcium Supplements in Pregnancy

Calcium and Your Pregnancy: A Comprehensive Guide for Expecting Mothers


Calcium plays a vital role in the health of both mother and baby during pregnancy. This essential nutrient contributes to fetal development and ensures the mother’s well-being throughout the journey. This article is meant to help pregnant women have a healthy pregnancy by teaching them about the benefits of calcium supplements and giving them tips based on evidence from different credible sources.

The Role of Calcium in Pregnancy

Calcium is crucial for many aspects of fetal development and maternal health:

Fetal development

Formation of bones and teeth, with the fetus accumulating about 30 grams of calcium by the end of pregnancy
Development of the heart, nerves, and muscles

Maternal health

Maintaining bone density, supporting dental health, and preventing osteoporosis
Supporting nervous system function, muscle contractions, and blood clotting

Calcium Requirements during Pregnancy

A mother’s daily calcium intake is affected by many things, such as her eating habits, her culture, and the availability of calcium-rich foods. Pregnant women’s average daily calcium intake ranges between 650 and 900 mg/day.

Recommended daily intake

Experts recommend 1,000 mg of calcium daily for pregnant women aged 19–50 and 1,300 mg for pregnant adolescents aged 14–18. These guidelines are based on recommendations from the Institute of Medicine and the Committee on Obstetric Practice.

Meeting calcium requirements through diet

To meet your daily calcium requirements, include calcium-rich foods in your diet, such as dairy products, green leafy vegetables, nuts, seeds, and calcium-fortified foods. Maximize calcium absorption by limiting caffeine and sodium intake and considering food sources with higher bioavailability. It’s also essential to note that calcium absorption efficiency increases during pregnancy.

Calcium Supplementation in Pregnancy

Determining the need for supplementation

Please consult your doctor to assess the need for calcium supplements, the appropriate dosage, and when to start taking them.

Benefits of supplementation

Calcium supplementation during pregnancy can reduce the risk of pre-eclampsia by up to 55%, high blood pressure, and preterm birth, especially for women with low dietary calcium intake. These benefits are based on international recommendations.

Supplementation guidelines

Adopt a daily routine of taking supplements, preferably with meals. Separate calcium supplements from iron supplements by at least two hours to avoid interference with absorption. Ensure adequate vitamin D intake (600–1,000 IU daily) for optimal calcium absorption. Be careful about taking too much calcium because it can cause side effects like constipation or kidney stones.
