How to choose a ferrous gluconate manufacturer? A procurement guide for food-grade iron nutritional fortifier suppliers.

Ferrous gluconate (CAS 12389-15-0, molecular formula C12H22FeO14·2H2O, molecular weight 482.17) is a widely used iron‑fortifying ingredient in the food and dietary‑supplement industries. It appears as a grayish‑yellow or pale yellow‑green powder and is extensively employed in iron‑fortified foods, infant formulas, dietary supplements, and mineral‑supplemented animal feeds. For food manufacturers, nutritional‑product brands, and feed producers, selecting a ferrous gluconate supplier that offers consistent batch quality and provides complete certificates of analysis (COA) and third‑party test reports is critical to ensuring formulation compliance and consistent iron content in finished products.
