The Importance of Calcium

Calcium is a vital mineral that plays a crucial role in maintaining overall health and well-being. From promoting strong bones and teeth to assisting with normal muscle function and nerve transmission, calcium is involved in numerous bodily functions that are essential for proper functioning. However, many people fail to meet their daily calcium requirements, leading to potential health problems and deficiencies. In this article, we will explore the importance of calcium, recommended daily intake, sources of calcium, calcium absorption and bioavailability, and the impact of calcium on various aspects of health.

Function of Calcium

It has a myriad of functions in the body, but its most well-known role is in maintaining strong bones and teeth. About 99% of the calcium present in the body is stored in these structures, providing them with the necessary strength and structural integrity. It also contributes to blood clotting, muscle contraction, nerve transmission, and maintaining a regular heartbeat. Moreover, calcium is involved in supporting the function of enzymes, regulating hormones, and aiding in the release and storage of neurotransmitters.

Recommended Daily Intake

The daily recommended intake of calcium varies based on age, sex, and life stage. According to the National Institutes of Health, children between the ages of 1 and 3 require 700 milligrams (mg) of calcium per day, while individuals aged 4-8 need 1,000 mg. Adolescents aged 9-18, both male and female, should aim for 1,300 mg. Adults aged 19-50, both male and female, should consume 1,000 mg daily, while women over 50 and men over 70 should increase their intake to 1,200 mg. It’s important to note that these recommendations may vary based on individual health conditions or specific dietary needs.

Calcium Deficiency

Also known as hypocalcemia, occurs when the body doesn’t receive an adequate amount of this vital mineral. Inadequate calcium intake, poor absorption, or increased loss of calcium through urine can contribute to this deficiency. Symptoms can include muscle cramps, brittle nails, dry skin, tooth decay, weakened bones, and an increased risk of developing osteoporosis. In severe cases, hypocalcemia can lead to numbness, seizures, and abnormal heart rhythms. To prevent calcium deficiency, it is crucial to consume enough calcium-rich foods or consider supplementation when necessary.

Sources of Calcium

To meet your daily requirements, it’s essential to incorporate calcium-rich foods into your diet. Some of the best sources include dairy products, non-dairy sources, fortified foods, and supplements.

Dairy Products

Dairy products are a well-known and readily available source of calcium. Milk, cheese, and yogurt are not only rich in calcium but also provide other essential nutrients like protein, vitamin D, and phosphorus. However, individuals who are lactose intolerant or have dietary restrictions may need to explore other sources of calcium.

Non-dairy Sources

For those who cannot consume dairy products, there are plenty of non-dairy sources available. Leafy greens like kale, broccoli, and spinach are excellent sources of calcium. Additionally, fortified plant-based milk alternatives such as almond milk, soy milk, and rice milk can provide a significant amount of calcium. Other non-dairy options include tofu, beans, nuts, and seeds.

Fortified Foods

Many foods are now fortified with calcium to help individuals reach their daily intake goals. These include cereals, bread, orange juice, and even some bottled water. Checking food labels for calcium-fortified products can be an effective way to incorporate more calcium into your diet.


In some cases, calcium supplementation may be necessary to meet daily requirements. Calcium supplements are available in various forms, such as calcium carbonate and calcium citrate. However, it is important to discuss calcium supplementation with a healthcare professional, as excessive supplementation may lead to adverse effects or interfere with the absorption of other nutrients.

Calcium Absorption and Bioavailability

While consuming adequate amounts of calcium is essential, its absorption and bioavailability also play a crucial role in ensuring its effectiveness in the body. Various factors can affect absorption, including age, vitamin D levels, dietary fiber, and certain medications. On the other hand, there are ways to enhance or reduce absorption.

Factors Affecting Absorption

Age plays a role in the body’s ability to absorb calcium, with absorption typically being more efficient during childhood and adolescence. Vitamin D is also vital for absorption, as it helps the intestines absorb from the diet. However, excessive intake of caffeine, sodium, and alcohol can hinder absorption. Additionally, certain medications, such as corticosteroids, antacids, and some diuretics, can interfere with calcium absorption when used long-term.

Enhancing Calcium Absorption

To enhance absorption, it is crucial to ensure optimal vitamin D levels. Sun exposure, fortified foods, and vitamin D supplements can help maintain sufficient levels. Consuming calcium with vitamin C-rich foods or beverages can also improve absorption. Moreover, spreading out calcium intake throughout the day and combining it with meals can enhance absorption, as the body can only absorb a certain amount of calcium at a given time.

Reducing Calcium Bioavailability

While absorption is important, it is equally important to consider the bioavailability. Some substances can reduce bioavailability, meaning that the body is not able to use the ingested calcium effectively. Excessive intake of dietary fiber, particularly from sources like bran, can bind to calcium and hinder its absorption. Oxalates, present in certain foods like spinach and rhubarb, can also reduce absorption. However, it’s essential to note that these factors have a minimal impact on overall status when consumed as part of a balanced diet.
