Calcium lactate is a white crystalline salt made by the action of lactic acid on calcium carbonate. Calcium lactate is used in foods (as a baking powder) and given medicinally. Its E number is E327.Calcium lactate is often found in aged cheeses. Small crystals of Calcium lactate precipitate out when lactic acid is converted into a less soluble form by the bacteria active during the ripening process.

In medicine, calcium lactate is most commonly used as an antacid and also to treat calcium deficiencies. Calcium lactate can be absorbed at various pHs and does not need to be taken with food for absorption for these reasons.

Calcium lactate is added to sugar-free foods to prevent tooth decay. When added to chewing gum containing xylitol, Calcium lactate increases the remineralization of tooth enamel. Calcium lactate 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 also found in some over the counter (OTC) mouth washes.
