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.
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 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.
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.
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.

Calcium and Bone Health
Role in bone health cannot be overstated. It is the primary mineral responsible for building and maintaining healthy bones, promoting proper bone formation, and preventing conditions like osteoporosis and age-related bone loss.
Role in Bone Formation
During childhood and adolescence, It is crucial for the development and growth of bones. The body continually builds new bone tissue, and an adequate supply is necessary for this process. Without enough calcium, the body will start extracting it from the bones, weakening them and increasing the risk of fractures.
Maintaining optimal bone density is crucial for overall skeletal strength and reducing the risk of fractures. Adequate intake, in combination with other bone-supportive nutrients like vitamin D and magnesium, is essential for maintaining proper bone density.
Age-related Bone Loss
As we age, our bodies naturally start to lose bone mass. Post-menopausal women are particularly vulnerable to accelerated bone loss due to hormonal changes. Ensuring adequate intake can help slow down age-related bone loss, reducing the risk of fractures and maintaining bone health.
Calcium and Heart Health
It also plays a role in maintaining heart health, contributing to normal blood pressure, cardiovascular disease prevention, and heart rhythm regulation.
Studies have shown a correlation between adequate calcium intake and reduced blood pressure levels. Adequate intake, particularly from dietary sources, may help lower blood pressure and reduce the risk of developing hypertension.
While the relationship between calcium intake and cardiovascular disease is still being studied, some evidence suggests that an optimal intake may reduce the risk of heart disease. However, it’s important to note that excessive supplementation may have adverse effects on cardiovascular health, emphasizing the importance of obtaining it from dietary sources rather than relying solely on supplementation.
It also plays a vital role in regulating heart rhythm. Together with other electrolytes, it helps maintain a regular heartbeat and contributes to the electrical conduction system of the heart.
Calcium and Dental Health
Calcium’s influence extends to dental health as well, playing a crucial role in tooth formation and maintaining good oral hygiene.
Role in Tooth Formation
It is essential for tooth formation and enamel strength. Adequate calcium intake during tooth development stages, especially in childhood and adolescence, is crucial for strong and healthy teeth.
