Calcium citrate is an organic compound with the chemical formula C12H10Ca3O14. It is a food calcium fortifier and has a better absorption effect than inorganic calcium. Can be used for strengthening various foods, including infant formula, fruit juice, dairy products, solid drinks, sports drinks, cow's milk, soy milk, health products, and cereal products.

It is widely use in many fields like the following:

Food industry: Calcium citrate, as a calcium fortifier, is widely used in various foods, including infant formula, fruit juice, dairy products, solid drinks, sports drinks, milk, soy milk health products, grain products, etc. It can not only enhance the nutritional value of food, but also act as a preservative and stabilizer, extending the shelf life of food and maintaining its freshness and color.

In the pharmaceutical field, calcium citrate tablets are mainly used for calcium supplementation, promoting bone health, anticoagulation, and accelerating lactate breakdown. It is suitable for preventing and treating diseases such as calcium deficiency, hypertension, myocardial infarction, etc., and should be used under the guidance of a doctor. The absorption effect of calcium citrate is better than some inorganic calcium, so it is widely used in calcium supplementation and regulation.

In the field of agriculture: Although the application of calcium citrate in agriculture is not as widespread as in the pharmaceutical and food industries, it still has certain potential. Calcium citrate can regulate the acidity and alkalinity of soil, improve soil structure, enhance soil water and fertilizer retention capacity, and promote the growth and development of plant roots.

Feature of Calcium citrate:

High absorption rate and low gastrointestinal irritation: Calcium citrate is known for its high absorption rate, which can reach nearly 80%, far higher than other types of calcium supplements such as calcium carbonate. Due to its water-soluble properties, it can be absorbed by the human body without the assistance of stomach acid, resulting in less stimulation to the gastrointestinal tract, making it particularly suitable for people with gastrointestinal dysfunction or insufficient stomach acid.
Safety: Calcium citrate is an excellent food additive and nutrient fortifier that can be added and applied in the production of many foods, providing energy to the body and promoting growth and development.
Easy to absorb: Calcium citrate has no stimulating effect on the gastrointestinal tract and can be directly absorbed by the human body without being neutralized by stomach acid, with a high absorption rate. Its solubility is superior to other calcium biomaterials such as calcium phosphate and calcium sulfate, and it can efficiently and smoothly release calcium ions during the degradation process.
Nutritious: Citric acid in the product undergoes the tricarboxylic acid cycle, ultimately generating carbon dioxide and water to produce ATP, providing energy for the body and promoting growth and development.
Wide range of sources: Natural calcium sources with high calcium content such as eggshells and shells can be used to produce calcium citrate, which not only protects the environment but also achieves the great benefit of resources.
Functionalization: In the feed industry, calcium citrate is not only a high-quality calcium preparation, but also decomposes into citric acid in the gastric environment, which can lower the pH of the gastrointestinal tract and activate pepsinogen.
Good taste: Calcium citrate has a sour and sweet taste, like eating lemon flavored candy, suitable as a calcium supplement snack.
