Role of Calcium in Pregnancy: Top 5 Sources, Benefits & Tips

About 99% of fetal calcium for bone development is transferred from the mother during the third trimester of pregnancy.

The role of calcium in pregnancy is very important for both the baby and the mother.

Calcium helps build strong bones and teeth, supports the muscles and nerves, and ensures healthy heart function.

During pregnancy, the baby gets all the calcium it needs from the mother.

If the mother does not get enough calcium, her body will take it from her bones,

which can lead to bone loss and health problems in the future.

Understanding the role of different nutrients in pregnancy helps expecting mothers make better choices about their diet and health.

This mineral is not just about bones; it also plays a big part in preventing complications and helping both mother and baby stay healthy.

Why Is Calcium Important During Pregnancy?

The importance of calcium in pregnancy cannot be overstated. Calcium is needed more than ever when you’re pregnant. The body uses it for many things, including:

Supporting the Baby’s Growth: Calcium helps develop the baby’s bones, teeth, heart, muscles, and nerves. Without enough calcium, the baby’s development may be affected.
Protecting the Mother’s Bones: If a pregnant woman does not get enough calcium from food or supplements, her body will take calcium from her bones. This can lead to weaker bones and increase the risk of osteoporosis later in life.
Preventing High Blood Pressure: Calcium helps lower the risk of conditions like preeclampsia, which causes high blood pressure during pregnancy and can be dangerous for both the mother and the baby.
Supporting Muscle and Nerve Function: Calcium helps muscles contract properly and supports normal nerve functions, preventing cramps and muscle spasms.
Reducing Pregnancy Complications: Getting enough calcium lowers the risk of low birth weight and premature birth, making it vital for a healthy pregnancy.

So, the purpose of calcium in pregnancy goes far beyond building bones. It supports the overall health and well-being of both mom and baby.

How Much Calcium Do Pregnant Women Need?

Understanding the need for calcium in pregnancy can help ensure proper intake. The recommended daily intake of calcium for pregnant women is:

Before Pregnancy: 1,000 mg per day to build strong bones and prepare the body for future needs.
During Pregnancy: 1,000 mg per day for adult women and 1,300 mg per day for pregnant teens.
While Breastfeeding: 1,000 mg per day to support both the mother’s and baby’s health.

The role of calcium in pregnancy also depends on how well the body absorbs it. Vitamin D plays an important role in helping the body absorb calcium, so it’s essential to get enough vitamin D along with calcium.

Best Food Sources of Calcium for Pregnant Women

Eating a variety of calcium-rich foods is the best way to meet your daily nutritional needs. Here are some of the best sources:

Dairy Products: Milk, cheese, and yogurt are great sources of calcium. They are easy to include in your daily meals.
Leafy Green Vegetables: Broccoli, kale, spinach, and collard greens are high in calcium and also provide other important nutrients.
Fortified Foods: Many foods like orange juice, plant-based milk (like almond or soy), and breakfast cereals are fortified with calcium.
Nuts and Seeds: Almonds, chia seeds, and sesame seeds are good plant-based sources of calcium.
Fish with Bones: Sardines and salmon (with bones) are rich in calcium and also provide healthy fats and protein.

Function of Calcium in Pregnancy

The function of calcium in pregnancy is linked to many body processes. Besides building bones and teeth, calcium supports:

Heartbeat regulation
Blood clotting
Hormone release
Muscle movement

Because of these many functions, the role of calcium in pregnancy affects nearly every part of the mother’s and baby’s health.

Calcium Deficiency in Pregnancy

Not getting enough calcium can lead to serious health issues. Here are some causes and risk factors of calcium deficiency:

Poor Diet: Not eating enough calcium-rich foods.
Lack of Vitamin D: Without enough vitamin D, the body can’t absorb calcium well.
Medical Conditions: Issues like lactose intolerance or celiac disease can reduce calcium absorption.
High Demand: Pregnancy increases the body’s need for calcium.
Certain Medications: Some medicines can lower calcium levels in the body.

Symptoms of calcium deficiency can include muscle cramps, numbness, weak nails, and dental problems. In severe cases, it can lead to bone weakness and an increased risk of fractures.

Calcium Supplements During Pregnancy

Sometimes, food alone may not be enough to meet the increased need of calcium in pregnancy. That’s when supplements can help.

Supplements are recommended if:

Your diet lacks calcium.
You are lactose intolerant or vegan.
You have a medical condition that affects calcium absorption.

Tips for Taking Calcium Supplements:

Take in Small Doses: Calcium is absorbed better in smaller doses, so it’s best to split your supplement into two or more doses during the day.
Take with Vitamin D: This helps your body absorb the calcium more effectively.
Don’t Mix with Iron Supplements: Calcium can block iron absorption, so take them at different times.

Popular Calcium Supplements:

Caltrate 600+D3: Contains 600 mg calcium and 800 IU vitamin D3.
Citracal + D3: Easy to digest, with 315 mg calcium and 500 IU vitamin D3.

Even though calcium is important, taking too much can cause problems:

Kidney Stones: Too much calcium may lead to kidney stones.
Constipation and Bloating: Common side effects of calcium supplements.
Interference with Other Nutrients: Calcium can affect how your body absorbs iron, zinc, and magnesium.

To avoid problems, follow the recommended dosage and choose high-quality supplements.
