Calcium citrate

Calcium citrate is a calcium salt of citric acid. It is commonly used as a dietary supplement when there is a need for additional calcium intake. Calcium citrate is known for its high bioavailability, meaning it is easily absorbed by the body.

Chemical Composition

Calcium citrate is composed of calcium cations (Ca²⁺) and citrate anions (C₆H₅O₇³⁻). Its chemical formula is Ca₃(C₆H₅O₇)₂. It is typically found in a white, crystalline powder form.

Uses

Calcium citrate is primarily used as a dietary supplement to prevent or treat calcium deficiency. It is often recommended for individuals who have difficulty absorbing calcium from other sources, such as those with low stomach acid or certain gastrointestinal conditions. It is also used in the food industry as a preservative and to enhance the texture of certain products.

Health Benefits

Calcium citrate is essential for maintaining healthy bones and teeth. It plays a crucial role in various bodily functions, including muscle contraction, blood clotting, and nerve transmission. Adequate calcium intake is important for preventing osteoporosis and other bone-related disorders.

Dosage and Administration

Calcium citrate supplements are available in various forms, including tablets, capsules, and powders. The recommended dosage varies depending on age, gender, and specific health needs. It is often taken with meals to enhance absorption.

Side Effects

While calcium citrate is generally well-tolerated, some individuals may experience side effects such as gastrointestinal discomfort, constipation, or bloating. It is important to follow the recommended dosage and consult a healthcare provider if any adverse effects occur.

Comparison with Other Calcium Supplements

Calcium citrate is often compared to calcium carbonate, another common form of calcium supplement. Calcium citrate is more easily absorbed, especially in individuals with low stomach acid. However, calcium carbonate contains a higher percentage of elemental calcium, which means fewer pills may be needed to achieve the desired dosage.
