Copper Gluconate is a food-grade copper(II) salt of gluconic acid, a light-blue to blue-green fine powder widely used as a bioavailable copper source in dietary supplements, infant formulas, sports nutrition, and medical foods.We supply bulk Copper Gluconate sourced from leading China manufacturers, available in powder form for international food processing operations. Our Copper Gluconate is widely used in infant formula and dietary supplements, parenteral feeding solutions, vitamin/mineral tablets, functional beverages and animal feed trace-element supplementation.
Copper Gluconate is produced by the neutralisation reaction between gluconic acid and cupric hydroxide or cupric carbonate.
The resulting salt is highly water-soluble, odourless, slightly metallic tasting, and exhibits excellent bioavailability. It meets USP, FCC and EP pharmacopoeia standards and is approved for use as a copper fortificant worldwide.
