Calcium Lactate Gluconate
Calcium Lactate Gluconate is a mixed calcium salt of lactic and gluconic acids, designed for high solubility in water and used principally in effervescent calcium products.
The compound is a white to off-white granular powder. It carries a calcium content of roughly 13 percent, lower than carbonate or citrate, but its dissolution behaviour in water is dramatically better than that of any single-anion calcium salt of comparable cost.
We source bulk Calcium Lactate Gluconate from top China manufacturers for our partners. The manufacturer is in Henan. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
Calcium Lactate Gluconate is a relatively specialized product with a narrow range of grades.
The standard effervescent grade is granulated with a controlled particle size distribution that promotes rapid dissolution without excessive dust generation. This is the principal commercial form and serves the effervescent tablet, sachet, and instant-drink markets.
A fine-powder grade is produced for use in beverage premixes and powdered drink mixes where finer particle size aids dispersion.
A direct-compression grade carries an engineered bulk density and flow profile suitable for high-speed tableting of effervescent calcium tablets.
All grades meet pharmaceutical and food specifications, including Ph. Eur. and JP monographs where applicable. Calcium content, water content, and pH of the dissolved solution are the principal commercial specifications.
Applications
- Effervescent calcium tablets where rapid dissolution and a pleasant mouthfeel are required
- Calcium-fortified powdered drink mixes and instant beverages
- Pharmaceutical effervescent products including calcium-vitamin C combinations
- Pediatric calcium supplements in liquid and powdered formats
- Sports-nutrition rehydration formulations with calcium content
- Functional water and isotonic beverage applications
- Calcium fortification of clear beverages where carbonate or phosphate would haze
- Hospital and clinical-nutrition products requiring high-solubility calcium
- Hard candies and effervescent confectionery with calcium positioning
- Powdered electrolyte mixes for medical and sports use

How We Help Source Calcium Lactate Gluconate
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Calcium Lactate Gluconate out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Calcium Lactate Gluconate together with other ingredients such as Sodium Acetate, Calcium Citrate and Sodium Lactate into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Calcium Lactate Gluconate is approved for food and pharmaceutical use in major regulated markets.
The European Union permits the individual components calcium lactate (E327) and calcium gluconate (E578) as food additives under Regulation (EC) 1333/2008, and Directive 2002/46/EC lists both as authorised calcium sources in food supplements. The combined Calcium Lactate Gluconate is treated as a mixed salt of these permitted ingredients.
The U.S. Food and Drug Administration affirms calcium lactate and calcium gluconate as GRAS under 21 CFR 184.1207 and 184.1199 respectively. Use as a nutrient or firming agent is generally recognised.
JECFA has evaluated calcium lactate and calcium gluconate within the lactate and gluconate additive groups, with not-specified ADI status reflecting long histories of safe use.
Pharmacopoeial monographs for Calcium Lactate Gluconate appear in the European Pharmacopoeia. Halal and Kosher certifications are routinely available given the mineral-and-fermentation origin.
Manufacturing Process
Calcium Lactate Gluconate is produced by co-reaction of lactic acid, gluconic acid, and a calcium source in aqueous solution.
Lactic acid and gluconic acid are dissolved in water in a calibrated molar ratio, typically with gluconic acid in excess relative to lactic acid. Calcium carbonate is then added portionwise, with stirring and mild heating, until carbon dioxide evolution ceases and the solution clarifies.
The resulting clear solution is filtered to polish out any insoluble particles, then concentrated by evaporation. The mixed salt is recovered either by crystallisation on cooling or by spray-drying of the concentrated liquor. Spray-drying is the more common modern route and gives the characteristic free-flowing granular product.
The product is hygroscopic and is packaged in moisture-barrier containers immediately after drying.
Both starting acids are produced by fermentation. Lactic acid is made by fermentation of glucose or sucrose with Lactobacillus species. Gluconic acid is produced by oxidative fermentation of glucose by Aspergillus niger or by enzymatic oxidation with glucose oxidase. The calcium source is mineral-origin limestone-derived calcium carbonate.
