Zinc gluconate

Zinc gluconate (CAS 4468-02-4) is an organic zinc salt used in food, pharmaceutical, and personal care manufacturing as a bioavailable zinc source for supplementation and fortification.

Where is Zinc gluconate used?

• Dietary supplements and OTC pharmaceuticals: active ingredient in lozenges, tablets, and syrups for immune support
• Food and beverage: zinc fortification of infant formula, functional drinks, and cereals
• Personal care: anti-acne creams, oral care products, and deodorants that regulate sebum and control odor-causing bacteria
• Pharmaceutical compounders use it as a zinc source in parenteral nutrition formulations.

Good to know: Preferred over inorganic zinc salts in finished formulations due to its high absorption rate; well-tolerated in oral and topical applications.

Commercial specifications

• Purity typically 97–102% on a dry basis
