kalciumsitrat

Kalciumsitrat, known in English as calcium citrate, is a calcium salt of citric acid. It appears as a white, odorless, crystalline powder or granular solid. Calcium citrate is commonly used as a dietary supplement to provide calcium, an essential mineral necessary for maintaining healthy bones and teeth, as well as supporting muscle function, nerve transmission, and blood clotting.

This compound is highly soluble in water, making it easily absorbable in the gastrointestinal tract, which makes it a preferred calcium source for individuals with certain medical conditions or those taking medications that interfere with calcium absorption. Calcium citrate’s bioavailability is often higher than that of other calcium salts, such as calcium carbonate, especially when taken on an empty stomach.

In addition to its use as a dietary supplement, calcium citrate is employed as a food additive (E333) to regulate acidity and act as a preservative. It is also used in pharmaceutical formulations and in the production of antacids to relieve acid indigestion and heartburn.

Calcium citrate is generally considered safe when used within recommended dosages. Potential side effects are rare but may include gastrointestinal discomfort, such as bloating, gas, or constipation. Excessive intake can lead to hypercalcemia, a condition characterized by elevated calcium levels in the blood, which can cause symptoms like nausea, confusion, and abnormal heart rhythms.

Manufacturers produce calcium citrate through chemical reactions involving calcium salts and citric acid, ensuring purity and quality suitable for medical and food applications. It is regulated by health authorities worldwide to ensure safety and efficacy in its various uses.
