Calcium lactate is a salt that consists of two lactate anions for each calcium cation (Ca2+). It is prepared commercially by the neutralization of lactic acid with calcium carbonate or calcium hydroxide. Approved by the FDA as a direct food substance affirmed as generally recognized as safe, calcium lactate is used as a firming agent, flavoring agent, leavening agent, stabilizer, and thickener. Calcium lactate is also found in daily dietary supplements as a source of calcium. It is also available in various hydrate forms, where calcium lactate pentahydrate is the most common.

5 Pharmacology and Biochemistry
5.1 Pharmacology

Both components of calcium lactate, calcium ion and lactic acid, play essential roles in the human body as a skeletal element an energy source, respectively.


5.2 ATC Code

A - Alimentary tract and metabolism

A12 - Mineral supplements

A12A - Calcium

A12AA - Calcium

A12AA05 - Calcium lactate


5.3 Absorption, Distribution and Excretion

Absorption

In order to be absorbed, calcium must be in its freely soluble form (Ca2+) or bound to a soluble organic molecule. Calcium absorption mainly occurs at the duodenum and proximal jejunum due to more acidic pH and the abundance of the calcium binding proteins. The mean calcium absorption is about 25% of calcium intake (range is 10 40%) in the small intestine, and is mediated by both passive diffusion and active transport.


Route of Elimination

Following oral administration to a human volunteer, 20 to 30% of a dose of lactic acid of up to 3000 mg was excreted via the urine during a period of 14 hours.


Volume of Distribution

The majority of calcium absorbed (99%) is stored in the skeleton and teeth for structural integrity.


Clearance

No pharmacokinetic data available.


5.4 Metabolism/Metabolites

In hepatic gluconeogenesis, lactic acid is converted to glucose. Lactic acid may be further catabolyzed in the lactic acid cycle.

5.5 Biological Half-Life

No pharmacokinetic data available.


5.6 Mechanism of Action

In aqueous environments such as the gastrointestinal (GI) tract, calcium lactate will dissociate into calcium cation and lactic acid anions, the conjugate base of lactic acid. Lactic acid is a naturally-occurring compound that serves as fuel or energy in mammals by acting as an ubiquitous intermediate in the metabolic pathways. Lactic acid diffuses through the muscles and is transported to the liver by the bloodstream to participate in gluconeogenesis.
