What is Calcium Gluconate Used For?
Calcium gluconate (CAS 299-28-5, E578) is a water-soluble calcium salt used in food, beverage, supplement, and feed formulations where dispersion, sensory profile, and batch documentation are important procurement criteria. Permitted applications and use levels depend on the destination market and finished-product category.
Key Applications
- Food Fortification: Dairy alternatives, juices, cereals, and infant formula. Feed buyers can check our FAMI-QS feed-grade gluconate certification scope
- Dietary Supplements: Calcium tablets, chewable vitamins, effervescent powders
- Sports Nutrition: Electrolyte drinks and protein powders
- Nutrition Products: Non-pharmaceutical functional foods and formulated nutrition products
- Baking: Dough conditioner and leavening aid

Frequently Asked Questions
What is the difference between calcium gluconate and calcium carbonate?
Calcium carbonate contains more elemental calcium, while calcium gluconate is more water-soluble and can be easier to use in liquids, beverages, and other aqueous systems. Selection should be based on the elemental-calcium target, solubility, sensory profile, local rules, and validation in the finished formulation. WIS supplies food-grade and feed-grade calcium gluconate only, not pharmaceutical-grade or injection-grade material.
What is the minimum order quantity (MOQ) for calcium gluconate?
The commercial MOQ is 500 kg. Qualification samples or smaller quantities may be available subject to approval and stock. Final pricing depends on the agreed specification, packaging, Incoterm, destination, and volume.
Which entity holds the Halal and Kosher certificates?
Halal and Kosher certificates are held by Definly Chemicals, not WIS Biotech. Controlled copies may be requested where relevant. Buyers should confirm the certificate holder, named site, product/grade scope, validity, and destination-market acceptance before approval.
What countries do you export calcium gluconate to?
WIS supplies buyers in the Americas, Europe, the Middle East, Asia, and other regions. Before shipment, the buyer and WIS confirm the applicable specification, document package, labeling, and import requirements for the destination market.
How much elemental calcium does calcium gluconate provide?
Elemental calcium depends on hydration state and assay basis. The current WIS specification shown on this page sets calcium at a minimum of 8.9%; buyers should use the approved specification and batch COA for formulation calculations rather than a generic theoretical value.
