Zinc Gluconate is a food-grade zinc salt of gluconic acid, a white to off-white crystalline powder widely used as a highly bioavailable zinc source in dietary supplements, cold-relief lozenges, and fortified foods.We supply bulk Zinc Gluconate sourced from leading China manufacturers, available in powder form for international food processing operations. Our Zinc Gluconate is widely used in dietary supplements and multivitamins, immune-support products, complementary-food fortification, oral rehydration therapy and functional foods.
Zinc Gluconate is produced by neutralisation of gluconic acid with zinc oxide or zinc carbonate, followed by crystallisation and drying.
It is soluble in water, slightly astringent, and meets USP, EP, FCC and JP specifications. It is clinically proven to support immune function and is the active ingredient in many cold-shortening zinc lozenges.
