Calcium supplements help you hit your recommended daily calcium numbers – they help strengthen your teeth and bones, promote heart health, regulate blood pressure, and more.

Most people don’t get enough calcium from their daily diet alone. Taking a calcium supplement is the easiest and most affordable solution.

Calcium supplements are a great way to help keep your bones and teeth strong by making sure you hit your daily calcium goals.

Would you pay a few extra dollars per week to experience stronger teeth and bones and ensure adequate calcium nutrition? Taking too much calcium can be a bad thing, but most people don’t even come close.

We’ll cover this, along with the benefits, possible side effects, and details on how to take calcium supplements.

For holistic bone health, it delivers whole-food calcium, magnesium and multiple other trace minerals. NEW CHAPTER also adds a proprietary blend of Vitamins K2 and D3 to help your body absorb calcium properly and effectively.”

The slim, easy-to-swallow tablets are slow releasing for optimum absorption throughout the day.

What are calcium supplements?

Calcium is a mineral naturally found in foods and plays a number of important roles in your body.

Necessary for the building and strengthening of bones, calcium also helps in regulating blood pressure and contributes to better brain efficiency.

Your body can’t make calcium on its own, so it’s essential that your daily diet contains adequate amounts in order to stay healthy. Most people find it convenient to simply take a daily calcium supplement so they don’t have to worry about calcium content in their meals or meal replacement shakes.

Calcium supplements are designed to deliver concentrated doses of calcium. Usually offered in the form of a pill or capsule (although powdered calcium is gaining popularity with the trend of homemade workout shakes), calcium supplements are a great way to make sure that you are getting plenty of calcium, regardless of what you eat.

According to National Institute of Health, healthy adults should shoot for 1000+ mg of calcium every day (1).

(Most calcium supplements generally contain 500-1000 mg of calcium per serving, so achieving your daily calcium requirement shouldn’t be too difficult.)

What are the benefits of calcium supplements?

Most people only associate calcium with bone health.

Calcium actually has a lot more benefits than this, ranging from reducing the risk of colon cancer and kidney stones to preventing osteoporosis (2).

If you are experiencing symptoms of calcium deficiency, taking a daily calcium supplement might be all you need. Calcium supplements are the ultimate solution for treating symptoms of calcium deficiency and you don’t even need a prescription.

It is important to remember that calcium:

  • is essential for stronger bones
  • strengthens and protects your teeth
  • helps maintain optimal body weight
  • helps regulate blood pressure
  • protects the heart and cardiac muscles
  • regulates PH levels (like chamomile and camu camu)
  • helps maintain healthy gums
  • lessens symptoms of PMS
  • improves the transportation of nutrients throughout your body

Calcium supplements also have been used to prevent side effects of hypocalcaemia, a disease that affects hundreds of thousands of people every year (3).

What are the side effects of calcium supplements?

When taken as instructed, calcium supplements generally do not produce any major side effects.

In a few rare cases, some people experienced side effects of headache, muscle pain, nausea, drowsiness, constipation and dry mouth. If you take any other medications or supplements, you should probably consult with your doctor first to avoid side effects from mixing certain ingredients. 

Do not take calcium supplements in higher quantities than recommended by your doctor. Hypercalcemia, a condition where your body has too much calcium, can have very serious negative side effects.

Calcium is generally safe when taken during pregnancy and breast-feeding, provided the recommended dosage is followed.

People that have high levels of phosphate in the blood or even low levels of phosphate in the blood should consult with their doctors before taking a calcium supplement. Your calcium and phosphate levels have to be in balance, taking too much calcium can throw your balance off and harm your body.

For those that have hypothyroidism or an under-active thyroid, separate at least four hours between your thyroid medications and calcium (because it can interfere with thyroid treatment).

How to take calcium supplements?

Recommended daily intake of calcium varies according to your age and gender, but generally 1000 mg is needed for optimal health.

There is really no ideal time of the day to take the supplements. However, it is recommended that you take them separately from your multivitamins, as calcium is known to interfere with the absorption of iron (check out the top ranked multivitamin supplements for men and women). 


If you are worried that might not be getting enough calcium in your diet every day, taking a calcium supplement is definitely something to consider.

You can add up all the calcium content between your meals, but chances are, you aren’t reaching the targeted 1000+ mg per day.
