What is Zinc Gluconate Used For?
Zinc gluconate (CAS 4468-02-4) is a water-soluble zinc salt used by food and animal-nutrition formulators where dispersion, mineral content, taste profile, and batch documentation are important procurement criteria.
WIS Biotech manufactures food-grade and feed-grade zinc gluconate at our Shandong facility, with approximately 60,000 MT annual combined gluconate capacity. Product specifications and batch-specific COA data are supplied for customer review before approval.
Key Applications
Food and Beverage Fortification
Food-grade zinc gluconate is used as a mineral ingredient in fortified foods, powdered beverage systems, and other formulated products where water solubility and a mild taste profile are useful. Permitted use levels and labeling requirements depend on the destination market and finished-product category.
Feed Premixes and Animal Nutrition
Feed-grade zinc gluconate is supplied for mineral premixes and compound-feed formulations. Buyers should specify the target animal category, inclusion rate, destination market, contaminant limits, and required feed-safety documents so the correct grade and document set can be matched.
Formulation and Processing
Its water solubility can support dry-blend and liquid systems where consistent mineral dispersion is required. Customers should validate compatibility, stability, and dosage in their own formulation and regulatory context.
Zinc Gluconate Supplier and Manufacturer: Buyer Checklist
Direct answer: WIS Biotech manufactures and supplies zinc gluconate for food and feed applications. Buyers can qualify the product by grade, zinc content, contaminant limits, documentation, packaging, and delivered cost rather than comparing headline price alone.
- Specify grade and application: identify the finished product and target market so the food-grade or feed-grade specification and document set can be matched correctly.
- Verify active content: confirm the 97.0–103.0% assay, zinc content of at least 13.0%, and agreed heavy-metal limits on the specification and recent batch COA.
- State supply requirements: include packaging format, trial quantity, annual forecast, destination, delivery schedule, and Incoterm in the RFQ.
- Request documents before approval: ask for the product specification, recent COA, SDS, and the current certificates required by your quality team.
Use the zinc gluconate vs zinc sulfate comparison for source selection, the calcium vs zinc gluconate guide for formulation context, and the buyer sourcing checklist before requesting a quote.

Quality & Compliance
WIS Biotech zinc gluconate is manufactured within certified quality and food/feed safety systems, including FSSC 22000, BRCGS, and FAMI-QS where applicable to the selected grade and certified scope. Each production batch is tested against the agreed specification. Available documentation includes a batch COA, SDS, applicable certification documents, and country-of-origin documentation.
WIS supplies food-grade and feed-grade zinc gluconate only. Other grades are outside our manufacturing and sales scope.
Frequently Asked Questions
How should buyers specify zinc gluconate?
State the intended food or feed application, destination market, target zinc content, assay basis, heavy-metal limits, microbiological requirements, packaging, annual volume, and required certificates. WIS will match the appropriate specification and provide a recent batch COA for review.
What is the difference between zinc gluconate and zinc oxide?
Zinc oxide has a higher elemental zinc percentage, while zinc gluconate offers substantially greater water solubility. Buyers should compare delivered elemental-zinc cost, solubility, handling, contaminant limits, local regulatory status, and performance in the finished formulation.
Is your zinc gluconate suitable for vegan products?
No animal-derived raw materials are intentionally used according to the current manufacturing declaration. Buyers making a vegan or vegetarian claim should review the controlled declaration and their certification body’s requirements. Applicable Halal and Kosher certificates are available on request.
What is the MOQ for zinc gluconate?
The commercial-order MOQ is 1 MT. Representative samples and smaller qualification quantities may be available on request. Pricing depends on the agreed specification, packaging, volume, Incoterm, and destination.
Do you export zinc gluconate to the USA and Europe?
Yes. WIS supplies international customers in Europe, Asia, the Middle East, and other markets. Before shipment, the buyer and WIS confirm the applicable product specification, document package, labeling, and import requirements for the destination market.
Can you provide Halal and Kosher documentation?
Yes. Controlled copies of applicable Halal, Kosher, FSSC 22000, BRCGS, and FAMI-QS certificates are available on request. Applicability must be confirmed against the selected grade, production scope, and destination market.
