What does calcium do?


The human body uses calcium to build bones, blood vessels, and muscles. Your teeth are also made of calcium. Calcium is an essential nutrient that your body needs for good health, so it’s vital to know the benefits of getting enough calcium from food and how much you should aim to consume each day. In this article, we’ll discuss what calcium does in the body and why you might want to take a supplement or eat more foods rich in this mineral.

What Is Calcium and What Does It Do?

Calcium is a mineral found in bones, teeth, and blood. It’s also needed for many chemical reactions in the body, such as muscle contraction, blood clotting and cell membrane function. The most crucial role of calcium in the body is building strong bones, which helps protect against fractures. Bones need calcium to grow properly and stay healthy.

Your body can’t make all the calcium it needs on its own. You must get calcium from food or supplements. Foods high in calcium include dairy products like milk, yoghurt, cheese, and ice cream; leafy green vegetables; beans; nuts.

Calcium helps keep your bones strong and chemical reactions in your body working correctly.

Calcium also helps to keep the chemical reactions in your body working correctly, such as helping your heart to beat regularly and allowing you to use and store energy from food. Calcium is one of the most important nutrients for good health. It’s an essential nutrient that we need to stay alive, but it also plays a vital role in several bodily processes.

Calcium’s other roles include:

  • Helping your muscles contract and relax
  • Helping your nerves send messages between cells in the nervous system (such as those that control muscle movement)
  • Helps maintain strong bones. Calcium helps keep your bones strong and healthy by assisting them in holding together as they grow and change shape over time.
  • Helps regulate blood pressure, heart rhythm and nerve function. Calcium also regulates blood clotting, muscle contraction and relaxation — all vital functions for staying healthy!

Amount of calcium in food

Knowing how much calcium is in your food is essential to ensure you get enough calcium. The following chart lists some common foods and their calcium content per serving. Find your favourite and see if it’s giving you all the benefits of a healthy diet!

  • Dairy products: Milk (1 cup), cheese (1 oz.), yoghurt (8 oz.)
  • Green vegetables: Broccoli (raw), kale, bok choy, collard greens

These are just some examples of what people eat for breakfast or lunch regularly—but did you know that broccoli can also be eaten as an appetizer? It’s true! Broccoli offers many health benefits, like preventing cancerous tumours from forming in our bodies. And kale is another vegetable that protects against various diseases such as diabetes mellitus type 2 because its high fibre helps regulate blood sugar levels throughout our bodies.

So we don’t have to worry about having too much sugar rushing inside us all day long after eating something sugary, which would typically cause insulin spikes.

But instead will only cause slight rises due to how quickly those nutrients get absorbed into our bloodstreams without any complications causing any issues!

How Much Calcium Do You Need?

The recommended daily intake of calcium for adults is 1000 milligrams. Most people can get the bulk of their daily requirements from food, but some may need a supplement.

Calcium plays a vital role in many bodily functions, including bone formation and maintenance, nerve transmission, muscle contraction, blood vessel contraction, and relaxation (vasoconstriction).

Am I getting enough calcium?

Calcium is one of the essential nutrients you need to eat every day. You probably know it as a bone-building material, but did you know it’s good for your heart too? Calcium plays a role in maintaining healthy blood pressure levels and helping keep muscles working correctly. Many experts say that adults need about 1,200 milligrams of calcium each day. But how much do we consume? A recent study found that only half American adults consumed adequate calcium. And while some groups of people might be better off than others, certain factors make it harder to get enough calcium. Here are some things to consider:


Women over 50 years old need more calcium than younger women. Women who are pregnant or breastfeeding also need extra calcium.


People of African descent tend to have lower calcium intake than white Americans. This is partly due to cultural differences. For example, black families often eat meat-based meals instead of plant-based ones.

Body size

The larger your frame, the more calories you burn per hour, so eating fewer calories helps you lose weight. Eating less calcium means losing essential nutrients like protein and vitamin D.

Medical conditions

Some medical conditions can increase your risk of developing osteoporosis. These include diabetes, kidney disease, thyroid problems, and rheumatoid arthritis. If you have these conditions, ask your doctor what you should do to protect your bones.

Dietary habits

Certain foods can interfere with calcium absorption. Foods high in oxalates (like tea, coffee, chocolate, nuts, and seeds) can bind with calcium in the gut and reduce its absorption. Other foods that contain phytate, which binds with calcium, include whole grains, soybeans, and legumes.

What foods provide calcium?

Milk and other dairy products

Leafy green vegetables

Fortified foods such as tofu

Beans and other legumes; nuts and seeds; and grains such as quinoa, amaranth, and buckwheat

Fish with soft bones that you can eat, such as canned salmon and sardines

Even if you do not drink milk, many foods contain calcium.

Are there risks?

While too little calcium can harm your bones, too much can also have harmful side effects. Excessive calcium can cause kidney stones, high blood pressure and other conditions. If you’re taking calcium supplements or concerned that you may be taking too much of the mineral, talk with your doctor about how to reduce your intake.

When to take calcium supplements

If you’re taking a calcium supplement, it’s best to take it with food. Taking your supplements with food can help maximize the amount of calcium your body absorbs. Taking your calcium supplement at bedtime will likely absorb less than taking it with food because most people don’t eat right before sleep.

Calcium supplements may be taken at any time of day, but they should not be taken on an empty stomach as this could lead to gastrointestinal distress or constipation.

Amount of calcium

Calcium is essential for strong bones and teeth. Calcium naturally occurs in dairy products like milk, cheese, yoghurt, and ice cream. Calcium is available in many forms, such as tablets, capsules, liquid drops, and food supplements.


Calcium supplements are often recommended for bone health. But some people experience side effects like bloating, gas and constipation. A new study suggests that certain brands could be better tolerated than others. Researchers looked at data from nearly 3,500 women aged 50 and older who took calcium supplements daily for one month. They found that women who reported feeling well while taking their calcium had fewer gastrointestinal issues than those who felt worse. The researchers say it’s essential to find out what works best for you.

What prescriptions do you take?

Calcium supplements are often recommended to help prevent osteoporosis. But there are different calcium supplements, and some work better than others. Calcium citrate, for example, works best absorbed into the body; calcium carbonate works well if mixed with food or water. And while taking calcium supplements might seem like a no-brainer, some people don’t absorb all the calcium they take. So what do you do if you’re looking for ways to boost your bone health? Here are three things to consider:

Choose the Right Supplement

Many calcium supplements include tablets, capsules, liquids, powders, gels, and even foods fortified with calcium. Your doctor or pharmacist can recommend one type over another based on your age, gender, medical conditions, and lifestyle factors, such as whether you exercise regularly. For example, calcium citrate is generally considered the most effective form of dietary calcium because it helps build strong bones, teeth, and muscles. Calcium carbonate is less expensive and easier to swallow, but it doesn’t provide nearly the same amount of calcium as calcium citrate. If you’re concerned about getting enough calcium, talk to your doctor about how much you need. You may want to start out with a lower dose of calcium carbonate and gradually increase your intake over time.

Take Them With Food Or Water

The easiest way to ensure you absorb the maximum amount of calcium is to drink plenty of fluids throughout the day. This includes water, juice, tea, coffee, milk, and other beverages. When you consume calcium and food, it gets broken down into smaller particles that are easier for your body to absorb.

Don’t Overdo It

Taking too much calcium can lead to side effects such as constipation, nausea, vomiting, diarrhoea, stomach cramps, headaches, and muscle pain. Talk to your doctor if you notice any symptoms. Also, avoid taking calcium supplements during pregnancy unless directed by your physician. Women who are pregnant shouldn’t exceed 1200 mg per day.


Calcium is an essential mineral that helps build strong bones. Most people don’t realize it, but calcium is found in many foods besides milk. For example, you’ll find calcium in leafy green vegetables such as broccoli and spinach, nuts and seeds such as almonds and sesame seeds; beans, tofu, yoghurt; cheese, fish; meat, and eggs. However, calcium supplements are often recommended because they’re easier to swallow than foods high in calcium. But do you know what you’re getting?

The Food and Drug Administration recommends taking 600 mg per day of elemental calcium. This amount is equivalent to about one cup of dairy products each day. If you’re concerned about how much calcium you’re consuming, look up the amount of calcium in everyday food items. You can use a calculator online or add each item’s total number of calories.

You might think that calcium pills are the best way to get enough calcium in your diet. But there are several problems with taking calcium supplements:

  1. Most calcium pills contain synthetic forms of calcium. These aren’t absorbed well by the body, so they are wasted.
  2. Some calcium pills can cause stomach upset.
  3. Calcium pills are expensive compared to eating foods rich in calcium.
  4. Calcium pills can interfere with blood clotting, leading to heart attacks and strokes.

If you want to increase your calcium intake without eating lots of dairy products, try drinking fortified juices and smoothies. Many juice companies now offer calcium-fortified orange juice and other beverages. Some even make calcium-fortified sports drinks. 

And you can buy powdered versions of calcium carbonate at grocery stores. Just follow package instructions carefully. Citrate is one of the most popular forms of supplemental calcium. 

However, it is difficult to absorb because it needs to dissolve in the stomach before entering the bloodstream. If you do not have enough stomach acid, taking calcium citrate can cause problems like constipation.

To help increase absorption, take calcium citrate with food. This will allow the calcium citrate to mix with digestive juices, making it easier to digest and absorb.

Is there anything else I should know?

Some people are more likely to have trouble meeting calcium requirements because of lifestyle choices. Women who take birth control pills or men who use testosterone supplements lose bone density over time. Also, people who live in areas where the soil isn’t rich in calcium may struggle to absorb it. Finally, those who already have osteoporosis or low bone mass may require even more calcium. Amounts

Calcium is an essential mineral found naturally in foods like milk and cheese, but it’s also added to many processed foods. Most Americans consume less calcium than recommended. A recent study published in JAMA Internal Medicine suggests that we could benefit from consuming even more. Researchers analyzed data from nearly 500,000 adults over 12 years. 

They found that people who consumed 2,400 mg of calcium daily had a lower risk of osteoporosis, fractures, and hip fractures than those who consumed 1,500 mg of calcium.

The researchers suggest that the benefits of calcium are cumulative, meaning that taking in more calcium throughout life may help reduce the risk of chronic diseases such as diabetes, heart disease, and cancer.

While there isn’t much evidence that supplements improve overall health, some research suggests that certain types of calcium might be better absorbed than others. For example, calcium carbonate, often used in supplement form, seems to be better absorbed than dairy. However, calcium citrate, commonly found in antacids, doesn’t absorb well.

Women should take 1,000 milligrams of calcium daily, while men should aim for 1,200 mg. Pregnant or breastfeeding, you should take 1,000 mg of calcium daily. Risks of too little calcium

Calcium plays many roles in our bodies. 

It builds strong bones and teeth. It keeps muscles working correctly. And it helps regulate blood pressure and heart function. But adults who don’t consume enough calcium are more likely to suffer from osteoporosis. 

This is because they’re more prone to bone density loss over time. As a result, they’re more likely to fracture bones.

A lack of calcium can lead people to experience muscle weakness. They might feel tired without knowing why. And they could even become weak enough to fall down. of calcium supplements.

In addition to being an essential nutrient, vitamin D helps your body absorb nutrients such as iron, zinc, magnesium, and phosphorus. Vitamin D also plays a role in bone health and can help prevent osteoporosis. 

You may get enough vitamin D if you spend time outside during sunlight hours. However, if you live in a northern climate where the sun doesn’t shine much, you might need to take a daily multivitamin containing 400 IU of vitamin D.


Calcium plays a vital role in the body, but it’s not something you should take for granted. Knowing how much calcium you need and how much you are getting from your diet and supplements is essential. A healthy lifestyle can help keep your bones strong and prevent osteoporosis later in life. But if you have a specific medical condition or have had any complications with calcium, talk with your doctor before taking any supplements or making dietary changes that might affect your calcium intake.
