Calcium lactate gluconate (CLG) is a mixture of calcium lactate and calcium gluconate. In pharmaceuticals, it is widely used as a pharmaceutical calcium source with excellent bioavailability. In food and beverages, the outstanding characteristics of calcium lactate gluconate combining high solubility and neutral taste lead to new applications in a wide range of premium products.
Calcium lactate gluconate is a white, crystalline, odourless, tasteless powder. It is non-toxic and has physiologically excellent compatibility.
Calcium lactate gluconate displays high bioavailability, neutral taste and is highly soluble. It is used as a premium calcium source in pharmaceuticals. Scientific reviews of human studies revealed that calcium lactate gluconate was both significantly and more consistently able to increase bone mineral density than other calcium salts.
In food, it is particularly found in beverages and other applications where solubility is a sensitive matter, e.g. clear beverages and concentrated or instant preparations as well as for processing at low temperatures and in line blending. Calcium lactate gluconate shows the highest solubility among the calcium salts commonly used for mineral enrichment, with a initial solubility of 20-40 %.
Being a mixture of calcium lactate and calcium gluconate, calcium lactate gluconate is currently not listed in European or US Pharmacopeias. However, Jungbunzlauer calcium lactate gluconate meets the requirements for calcium lactate and calcium gluconate of the US Pharmacopeia (USP), the Food Chemicals Codex (FCC) and the Commission Regulation (EU) No. 231/2012, always in their latest version.
Besides calcium lactate gluconate 13 with a calcium content of 13 %, Jungbunzlauer also supplies calcium lactate gluconate with similar properties and 10 % calcium (type CLG 10).

Calcium lactate gluconate is a mixture of calcium gluconate and calcium lactate, it can be used in both pharmaceuticals and food applications, according to the regulations for the individual salts.
In Europe, calcium lactate (E327) and calcium gluconate (E578) are listed as generally permitted food additives and may be added to all foodstuffs, following the "quantum satis" principle as regulated in EU Regulation (EC) No. 1333/2008 (Annex 2), as long as no special regulations restricts the use.These salts are also allowed in food supplements (Directive 2002/46/EC) and in foods for particular nutritional uses (Directive 2001/15/EC). In addition to existing national allowances in some countries, calcium gluconate and calcium lactate are on the positive list of the new Regulation (EC) No. 1925/2006 on food fortification. It is listed as mineral salt in the EU Regulation (EC) No. 609/2013 on food intended for infants and young children, food for special medical purposes, and total diet replacement for weight control.
The US Food and Drug Administration (FDA) affirmed calcium lactate and calcium gluconate as generally recognised as safe (GRAS) food substances and permitted the use in food with no limitation other than current good manufacturing practice. Calcium lactate is listed in 21 CFR §184.1207, calcium gluconate in 21 CFR §184.1199.
