Other names

  • Calcium lactate
  • Calphosan
  • Conclyte calcium
  • Calcium dilactate

Product Description

Calcium lactate is used in medicine, mainly to treat calcium deficiencies; and as a food additive with E number of E327. Some cheese crystals consist of calcium lactate.

Calcium lactate can be prepared by the reaction of lactic acid with calcium carbonate or calcium hydroxide.

  • Calcium lactate is used in medicine as an antacid.
  • Calcium lactate is also used to treat hypocalcaemia (calcium deficiencies). 
  • Calcium lactate (or other calcium salts) is antidote for soluble fluoride ingestion and hydrofluoric acid.

Food industry

As firming agent, a flavor enhancer or flavoring agent, a leavening agent, a nutritional supplement, and a stabilizer and thickener.

  • Calcium lactate is an ingredient in some baking powders containing sodium acid pyrophosphate. It provides calcium in order to delay leavening.
  • Calcium lactate is added to sugar-free foods to prevent tooth decay. When added to chewing gum containing xylitol, it increases the remineralization of tooth enamel.
  • The compound is also added to fresh-cut fruits, such as cantaloupes, to keep them firm and extend their shelf life, without the bitter taste caused by calcium chloride, which can also be used for this purpose.
  • Calcium lactate is used in molecular gastronomy as a flavorless fat-soluble agent for plain and reverse spherification. It reacts with sodium alginate to form a skin around the food item.

Animal feeds

Calcium lactate may be added to animal rations as a source of calcium.


The compound was formerly an intermediate in the preparation of lactic acid for food and medical uses. The impure acid from various sources was converted to calcium lactate, purified by crystallization, and then converted back to acid by treatment with sulfuric acid, which precipitated the calcium as calcium sulfate. This method yielded a purer product than would be obtained by distilaltion of the original acid. Recently ammonium lactate has been used as an alternative to calcium in this process.

Water treatment

Calcium lactate has been considered as a coagulant for removing suspended solids from water, as a renewable, non-toxic, and biodegradable alternative to aluminum chloride.


Addition of calcium lactate substantially increases the compressive strength and reduces water permeability of bioconcrete, by enabling bacteria such as Enterococcus faecalis, Bacillus cohnii, Bacillus pseudofirmus and Sporosarcina pasteurii to produce more calcite.
