Copper gluconate

Copper gluconate (CAS 527-09-3) is the copper(II) salt of gluconic acid, used across food, pharmaceutical, and personal care manufacturing as a bioavailable source of dietary copper.

Its chelated structure makes it more stable and easier to incorporate into finished formulations than inorganic copper salts. In nutritional supplements and fortified foods, it delivers copper as a highly absorbable mineral source.

It frequently appears in tablets, capsules, and functional beverages. Pharmaceutical manufacturers use it in mineral formulation blends where consistent copper content and solubility are critical to dosage accuracy.

In personal care, it is incorporated into anti-aging and skin-conditioning products where copper peptide-adjacent formulations require a stable, water-soluble copper source for the best results.

Feed and premix producers use it to supplement copper in livestock and poultry diets, meeting defined mineral inclusion targets in compound feed. Copper gluconate is supplied as a fine blue-green powder.

Food-grade and USP-grade specifications are the most commonly sourced, with buyers typically requiring certificates of analysis confirming copper assay and heavy metal limits.

Packaging ranges from kilogram-scale bags to bulk quantities suited to industrial feed and supplement manufacturing. This ensures that the material remains stable during transport and storage.
