Kalsiumcitrat

Kalsiumcitrat, also known as calcium citrate, is a calcium salt of citric acid commonly used as a dietary supplement and food additive. It is prized for its high bioavailability and ease of absorption, making it an effective source of calcium for individuals with deficiencies or increased nutritional needs.

Chemically, calcium citrate is a crystalline powder that is soluble in water and has a mild, tart taste. It is often used in the manufacturing of calcium supplements, where it is available in tablet, capsule, or powdered form. Due to its good tolerability and low risk of gastrointestinal discomfort, calcium citrate is preferred over other calcium salts, such as calcium carbonate, especially for individuals with stomach acid deficiencies or those taking medications that can impair calcium absorption.

In addition to its nutritional applications, calcium citrate functions as a food additive designated by the E number E333. It is used as a stabilizer, acidulant, or pH regulator in various food products, including baked goods, beverages, and processed cheeses.

Calcium plays a vital role in maintaining healthy bones and teeth, supporting muscle function, nerve transmission, and blood clotting. Adequate intake of calcium, through diet or supplements like calcium citrate, is important for preventing osteoporosis and other calcium-deficiency-related conditions.

While generally regarded as safe when used as directed, excessive intake of calcium citrate can lead to side effects such as kidney stones or gastrointestinal discomfort. It is advisable to consult healthcare professionals before starting supplementation, especially for individuals with underlying health conditions or those taking certain medications.
