Why Take Calcium Supplements?
Introduction
Calcium is an essential mineral for the proper functioning of our body. It is crucial for maintaining strong bones and teeth, facilitating muscle contraction, and supporting blood clotting. However, our body does not produce calcium on its own, meaning we must obtain it daily from our diet.
In some cases, it can be difficult to reach an adequate calcium intake through food alone, especially if you are lactose intolerant or follow a specific diet. This is why taking calcium supplements may be necessary to maintain bone health and prevent conditions like osteoporosis in the long term.
Why Take Calcium Supplements?
Calcium supplementation may be necessary if dietary intake is insufficient. This can be due to specific diets, such as a vegan diet or lactose intolerance, since dairy products are often a major source of calcium. As we age, our calcium needs increase, particularly to maintain bone density and prevent diseases like osteoporosis. Supplementation is especially essential for older adults or those with osteopenia.
Beyond supporting bone health, calcium plays a key role in dental health, muscle function, and cardiovascular health, as it helps regulate muscle contraction, including that of the heart.

5 Health Benefits of Calcium
1. Strengthening Bones and Teeth
Calcium is the main component of our bones and teeth. It ensures their strength and helps maintain bone density over time. Adequate calcium intake prevents bone loss, which is essential for reducing the risk of osteoporosis, a condition that weakens bones and increases fracture risks.
2. Osteoporosis Prevention
With age, bone mass naturally decreases, especially in postmenopausal women. Calcium supplementation, when combined with vitamin D, helps slow this process and reduces the risk of fractures related to osteoporosis.
3. Improving Muscle Contraction
Calcium plays a key role in muscle contraction, including heart muscle function. It helps muscles contract and relax properly, which is essential for blood circulation and digestion.
4. Hormonal Regulation
Calcium contributes to the release of essential hormones involved in biological processes, such as metabolism regulation. By balancing certain hormones, calcium helps maintain the body’s internal stability, which is vital for overall health.
5. Improved Absorption with Vitamin D and Magnesium
To be effectively absorbed by the body, calcium needs supporting nutrients such as vitamin D and magnesium. Together, they optimize calcium utilization, ensuring better bone and muscle health.

How to Choose a Calcium Supplement?
When choosing a calcium supplement, consider the form of calcium, concentration, and bioavailability to ensure optimal absorption and meet your specific needs.
| Type of Calcium | Characteristics | Benefits | Recommendations |
|---|---|---|---|
| Calcium Carbonate | Common form, derived from sources like oyster shells or dolomite. | Best absorbed when taken with food. | Recommended for those who can take it with meals and have no digestive issues. |
| Calcium Citrate | More easily absorbed, even without meals. | Ideal for people with low stomach acid (such as older adults). | Recommended for those with digestive disorders or who don’t consume dairy. |
| Plant-Based Calcium | Derived from vegetable sources, often enriched with vitamin D and magnesium. | Suitable for vegans and vegetarians; generally well absorbed with vitamin D. | Ideal for those following a vegan diet or lactose intolerant individuals. |
| Chelated Calcium | Bound to amino acids for better absorption. | High bioavailability, particularly for those with absorption issues. | Recommended for those with high calcium needs or absorption disorders. |
| Coral Calcium | Natural source rich in minerals but may contain trace metals. | Provides a mix of minerals for added benefits. | A natural option but should be avoided if concerned about metal contamination. |
Importance of Concentration and Bioavailability
The calcium concentration varies depending on the product. For example, calcium carbonate contains 40% elemental calcium, while calcium citrate contains only 21%. However, despite lower concentration, calcium citrate is often better absorbed. Bioavailability (absorption capacity) is a key factor, especially for those with digestive issues or who do not consume dairy.
Recommendations Based on Individual Needs
- Vegan or lactose-intolerant? Opt for plant-based calcium such as Garden of Life Plant-Based Calcium.
- Digestive issues or absorption problems? Choose highly bioavailable forms like chelated calcium or calcium citrate.
- Older adults or low stomach acid? Calcium citrate is ideal since it absorbs well without food.

Conclusion
Taking calcium supplements is essential for maintaining strong bones and overall health, especially if your diet does not provide enough calcium—such as for those who are lactose-intolerant or on a vegan diet. Calcium plays a critical role in bone and dental strength, osteoporosis prevention, and ensures important functions such as muscle contraction and hormone regulation. By choosing the right supplement for your needs, you can maximize calcium absorption and protect your health in the long run.
