Magnesium Gluconate Manufacturer for Food, Supplement and Feed Applications
Magnesium gluconate dihydrate (CAS 59625-89-7) is the magnesium salt of gluconic acid supplied on a dihydrate specification basis. It is used as a mineral source in dietary supplements, fortified foods, beverage powders, and selected feed formulations. For commercial qualification, buyers should assess the intended use, destination-market rules, magnesium content, hydration state, solubility, impurity limits, and supporting batch documents rather than relying on a generic grade name.
WIS Biotech manufactures food-grade and feed-grade magnesium gluconate in Shandong, China. Since 2015, our gluconate facility has supported ingredient distributors, contract manufacturers, food and beverage producers, and premix buyers in more than 80 countries. Buyers can request the current specification, SDS, recent batch COA, applicable certificates, packaging options, and a destination-based quotation.
Magnesium Gluconate Applications
Dietary Supplements and Mineral Blends
Magnesium gluconate can be formulated into tablets, capsules, gummies, sachets, and multi-mineral blends. Formulators should calculate the required ingredient weight from the approved batch specification and verify compatibility, sensory performance, serving size, and local maximum levels in the finished product. See how it compares with other gluconate minerals for dietary supplements.
Functional Beverages and Powdered Drinks
Its water solubility makes magnesium gluconate a candidate for hydration powders, beverage premixes, and liquid systems. Actual clarity and stability depend on concentration, pH, temperature, processing sequence, and interactions with acids, flavours, sweeteners, and other minerals. WIS can provide samples and current technical data for formulation trials.
Food Fortification
Magnesium gluconate may be used as a magnesium source in appropriate fortified-food and supplement applications where permitted. Codex identifies magnesium gluconate as INS 580 and JECFA publishes an identity and purity specification. This international identifier should not be treated as proof of authorisation for every product category or destination market.
Feed and Premix Use
Feed-grade magnesium gluconate is supplied for mineral premixes and other feed applications subject to the buyer’s formula, species, inclusion level, and local feed rules. Feed buyers should confirm the selected grade, production scope, specification, and applicable certification documents before approval.
Magnesium Gluconate Supplier: Procurement Checklist
- Define the application: state the finished-product type, destination market, required grade, and target elemental magnesium contribution.
- Approve the specification: compare assay, magnesium content, hydration basis, pH, solubility, and impurity limits with a recent batch COA.
- Confirm documents: request the current specification, SDS, COA, origin documents, and certificates applicable to the selected grade and site.
- Set commercial terms: provide trial and annual volume, packaging, destination, required delivery date, and Incoterm.

Packaging and Supply
Standard packaging is 25 kg net multi-layer kraft paper bags with an inner PE liner. FIBC options may be available for approved orders. Store sealed in a cool, dry, well-ventilated place away from direct sunlight and incompatible materials.
Commercial MOQ: 500 kg. Qualification sample availability and lead time depend on grade, stock, packaging, destination, order volume, and courier or freight conditions; final availability, container loading, freight basis, and delivery schedule are confirmed in the quotation.
Quality and Documentation
Each commercial shipment is supported by a batch COA and SDS, with origin and shipping documents prepared for the agreed transaction. WIS Biotech holds FAMI-QS, FSSC 22000, and BRCGS certifications. Halal, Kosher, and ISO certificates are held by Definly Chemicals. Buyers should verify the holder, named site, product/grade scope, validity, and destination-market acceptance against the current controlled documents. WIS Biotech does not offer pharmaceutical-grade or injection-grade magnesium gluconate.
Frequently Asked Questions
How does magnesium gluconate compare with magnesium citrate?
Both can be used as magnesium sources, but they differ in elemental magnesium content, hydration state, solubility, sensory profile, and formula behaviour. The suitable option depends on the target dose, serving size, product format, destination-market rules, and results from finished-product trials. WIS supplies food-grade and feed-grade magnesium gluconate, not pharmaceutical-grade material.
What elemental magnesium content does WIS Biotech specify?
The supplied TDS specifies 5.29%–5.50% magnesium calculated as dihydrate and 98.0%102.0% assay. Formulators should use the mutually approved specification and batch COA for calculations.
Is magnesium gluconate suitable for clear beverage formulations?
It is soluble in water and can be evaluated for beverage applications, but clarity and stability must be confirmed in the buyer’s finished matrix. Concentration, pH, temperature, processing order, acids, flavours, sweeteners, and other minerals can affect performance. Samples and available solubility data can be requested for qualification trials.
What is the MOQ and lead time for magnesium gluconate?
The commercial MOQ is 500 kg. Qualification sample availability and lead time depend on grade, stock, packaging, destination, order volume, and courier or freight conditions; confirm them in the current quotation.
How should buyers interpret INS 580 for magnesium gluconate?
INS 580 is the Codex identifier for magnesium gluconate, and JECFA publishes an identity and purity specification. It should not be presented as blanket authorisation under every national or regional food-additive system. EU buyers should assess the intended use under the applicable food-supplement, fortification, or other product rules and confirm compliance for the finished product.
Are Halal and Kosher documents available?
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.
GCC buyers: see Halal documentation for the UAE & GCC.
