Best Calcium Supplements: Top 10 Brands Reviewed

The most abundant mineral, calcium, is stored primarily in the teeth and bones. Unfortunately, many people do not eat the necessary amount to ensure they get the calcium their body needs. Thus, calcium supplements are a convenient way to get the needed amounts of calcium.

​When a person does not consume enough calcium-rich foods, the body pulls calcium from the bones, which can weaken their bones and teeth. Additionally, because calcium is pulled from the bones so often, the bones in the body are replaced every decade.

However, patients should understand that calcium is needed for other things in the body, including blood clotting, muscle contractions, hormone secretion, and optimal nerve transmission. Calcium that is circulated in the blood helps balance the body's pH level.

When the pH balance becomes disrupted in the body, sleep difficulties, pain, heart disease, edema, high blood pressure, weakness, fatigue, and decreased immunity can occur.

What Does Health Benefits Calcium Offer

1) Bone Health

During adolescence and early adulthood, bones solidify and achieve their peak mass. The more mass the bones have at this time, the longer the body can prevent bone loss, or osteoporosis, from occurring.

​Osteoporosis is the leading cause of broken bones in elderly patients. ​In fact, more than 10 million American adults are affected by this condition.

2) Cancer Prevention

Studies have shown that consuming ample amounts of calcium can reduce the risk of colon and rectal cancers; however, more studies need to be completed to determine if calcium supplements can help decrease a person's colorectal cancer risk.

​Additionally, calcium supplements can lead to heart attacks; therefore, most physicians recommend getting this important mineral from food to decrease the risk of cardiovascular disease.

3) Weight Management

Calcium helps bind fat in the digestive system to help prevent the body from absorbing excess fat. ​Therefore, increasing your calcium intake can help to lower your body weight.

4) Cardiovascular Health and Blood Pressure

​Calcium helps to smooth the muscles, veins, and arteries in the body, which can help lower blood pressure. In fact, cardiologists recommend a diet high in calcium to lower blood pressure.

​When choosing dairy products, it has been shown that it is better to opt for full-fat dairy products rather than low-fat dairy products.

5) Helps Ensure Proper Function of Muscles and Nerves

​Calcium is a big part of the way your brain releases neurotransmitters that are responsible for moving your muscles and nerves, sending signals to each other.

​Calcium can help your cells communicate, relying on nerve responses, and helps activate important proteins that your body uses to move and contract your muscles.

​Calcium is also involved with glucose control, impacting the amount of sugar in your blood, used by your muscles as fuel.

6) Diabetes Prevention

Some studies have indicated that consuming calcium and Vitamin D together can help optimize your body's metabolism of glucose, preventing diabetes. Calcium and Vitamin D may also affect the cells of the pancreas, directly controlling the secretion of insulin and, thus, the level of blood sugar.

​Calcium is essential to the processes of the cells in the human body, especially those that are responsive to insulin, such as fat and muscle tissue.

​In a 20-year study by Nurses' Health, over 80,000 women without a history of diabetes were followed, and their consumption of calcium and Vitamin D supplements was checked every 2 to 4 years.

During this 20 year span, the study found that having an intake that exceeds 1,200 mg of calcium and 800 IU of Vitamin D resulted in a 33 percent lower risk of developing Type 2 Diabetes.

7) Necessary for Optimal Dental Health

​The body stores some of its calcium in your teeth, making it essential for the health and maintenance of your teeth.

​Calcium can help protect your teeth from decay and has been linked with improved dental health for the same reasons it helps protect your bones.

8) Helps Treat Indigestion

Calcium is frequently found in over-the-counter treatments for heartburn, upset stomach, and indigestion. However, antacids can sometimes simply reduce the amount of acid in your stomach, which can actually worsen the problem.

In fact, nearly 80 percent of cases of acid reflux are caused by low amounts of stomach acid.

​The actual cause of the reflux is food that sits too long in your stomach without enough acid for digestion, and it ferments, releasing pressure and gas that opens the LEM valve located between the stomach and esophagus.

​This lets stomach acid out of the stomach where it causes that familiar pressure or burning sensation in your chest. Taking a regular calcium supplement can help improve the function of the LEM muscle, reversing the symptoms often associated with acid reflux or GERD.

9) PMS Prevention

Calcium can also be helpful when taken to relieve the symptoms of PMS, including cramps, tenderness of the breast, fatigue, bloating, moodiness, muscle aches, and headaches.

Calcium levels can fluctuate as you progress through the menstrual cycle. As estrogen increases, calcium levels drop. Adding a calcium supplement will help balance this out, reducing the symptoms associated with this painful condition.

Calcium plays a critical role in the human body. It is required for the proper functioning of cells, nerves, bone, and muscle. If the blood is low in calcium, the body starts taking calcium from the bones, which in turn weakens the bones.

​Having the right amount of calcium in the body is critical to building and maintaining healthy bones. Although there is a debate on whether calcium is needed as a dietary supplement, its intake may lead to more benefits in certain situations.

Calcium deficiency is common and is a result mostly from nutrition and bad habits such as smoking, alcohol, and excess coffee. Calcium deficiency is directly related to the deficit of vitamin D and magnesium.

​When deficit occurs, as well as in the case of osteoporosis or the risk of such (which is extremely common with women), taking calcium as a supplement is strongly recommended.

Calcium citrate is an acceptable source of calcium, as it is well absorbed and leads to increased bone mass. It is advisable to combine calcium with food when you take it together with vitamin D.

What Are Calcium Supplements Used For​

Calcium supplements are used to treat or prevent low blood calcium levels in those that don't get sufficient calcium from their diets. ​The supplements are utilized in the treatment of conditions caused by low levels of calcium in the body such as:

• bone loss;
• weak bones;
• certain muscle disease;
• decreased activity of the parathyroid gland. 

Calcium supplements are also used in some patients to ensure that they get sufficient quantities of calcium. ​Patients that should be getting adequate amounts of calcium include postmenopausal women, women who are nursing, pregnant women, and people taking medications such as prednisone, phenobarbital, or phenytoin.

​Usage and Dosage of Calcium Supplements

• Calcium supplements are taken by mouth with food.
• Calcium supplements containing calcium citrate can be taken either with or without food.
• ​It is important to follow the directions provided on the product packaging or as directed by a physician.
• If your daily recommended dose is over 600 milligrams, you should divide it and space it throughout the day for the best absorption.
• If you are not sure about any of the information, consult your pharmacist or physician.
• ​If you are using a chewable product, ensure that you chew well before you swallow.​
• If using an effervescent tablet, you should allow it to dissolve fully in a glass of water before you drink it.
• Avoid chewing or swallowing the tablet whole.
• If you are using a powder or liquid product, use a dose-measuring device or spoon to measure the supplement and ensure that you get the right dosage.
• Avoid using a household spoon. If the liquid product you are using is a suspension, shake the bottle well before taking it.
• ​Use calcium supplements regularly if you wish to get the most benefit. To ensure that you don't forget, get your supplement at the same time or times each day.

​If the doctor recommends following a special diet, ensure that you do to get the most benefit from the product and avoid any serious side effects.

What If You Miss a Dose

If you miss a dose of your calcium supplement, take it once you remember. 

However, if you remember to take the supplement when it is too close to the time for your next dose, just skip your missed dose and proceed with the usual dosing schedule. ​Don't ever double the dosage to catch up.

​Is There a Possibility of Overdose

If overdose is suspected, contact an emergency room or poison control center immediately. ​The symptoms of calcium supplement overdose include:

• tiredness;
• weakness;
• headache;
• mental/mood changes;
• loss of appetite;
• nausea/vomiting.

However, it is very unlikely to overdose with calcium supplements in case you take an adequate dosage.

Side Effects of Calcium Supplements

Upset stomach and constipation are the most common side effects associated with calcium supplements.

If any of the side effects worsen or persist, inform your pharmacist or doctor immediately. However, most people never experience any serious side effects after taking calcium supplements. 

If you experience any of the following side effects:

• unusual tiredness;
• weakness;
• increased urination/thirst;
• headaches;
• muscle/bone pain;
• mood/mental changes;
• abnormal weight loss;
• loss of appetite;
• vomiting/nausea, inform your doctor immediately.

It is very rare to experience a severe allergic reaction after taking calcium supplements. However, seek medical attention if you notice any symptoms of a serious allergic reaction including trouble breathing, rash, severe dizziness, and swelling/itching of the throat, tongue, or face. 

​The list of side effects provided here is far from exhaustive. If you do notice other side effects not listed here, ensure that you contact your pharmacist or doctor. 

​Precautions When Taking Calcium Supplements

Inform your pharmacist or doctor if you have any allergies before you start taking calcium supplements. The supplements may contain inactive ingredients that can cause allergic reactions or various other problems. Talk to your doctor or pharmacist for more information.

You should not use calcium supplements if you suffer from certain medical conditions such as:

• kidney stones;
• kidney disease;
• a disease of the pancreas;
• heart disease;
• little to no stomach acid;
• high calcium levels;
• malabsorption syndrome;
• certain lung diseases. 

​If you suffer from phenylketonuria or a different condition that requires limiting your intake of aspartame, consult your pharmacist or doctor about using calcium supplements safely since some sugar-free formulations of calcium supplements contain aspartame. 

​Drug Interactions

If you are taking calcium supplements under instructions from your doctor, it is likely that they are already aware of the possible drug interactions and may be monitoring you for them.

Never stop, start, or alter the dosage of any calcium supplement before you check with your pharmacist or doctor first. Inform your physician or pharmacist before using calcium supplements if you are using any of the following products:

• certain phosphate binders such as calcium acetate;
• cellulose sodium phosphate;
• digoxin.

Calcium can inhibit the absorption of other drugs including tetracycline antibiotics, bisphosphonates, levothyroxine, estramustine, and quinolone antibiotics such as levofloxacin and ciprofloxacin. Ensure that you separate doses of the medications listed above from your doses of calcium supplements.

​Ask your physician about how long to wait between doses and for assistance in finding a dosing schedule that works with all your medications. Check the labels on all your prescription and nonprescription medications since they may contain calcium. 

​Notes About Taking Calcium Supplements

Calcium-rich foods include dairy products (such as ice cream, cheese, yogurt, and milk), dark-green leafy vegetables (such as spinach and broccoli), and calcium-fortified foods such as orange juice.

Calcium-rich foods help in calcium absorption. Vitamin D also helps with calcium absorption. Vitamin D rich foods include fatty fish, fortified dairy products, cod liver oil, sardines, chicken livers, and eggs.

​The Bottom Line

Calcium supplements can be highly beneficial to your body, but you need to take the right dosages and to follow the right directions to avoid any unwanted side effects. 

Always ensure that you consult your physician or pharmacist before you start taking any calcium supplements or if you experience any serious side effects after taking them.
