Description

Citric Acid, Iron(3+) Salt is a coordination complex formed from citric acid and ferric iron. This compound is valued for its role as a bioavailable and well-tolerated source of iron, essential for addressing nutritional deficiencies. It is primarily required by manufacturers in the pharmaceutical, nutraceutical, and fortified food industries for producing dietary supplements and functional ingredients.

Application

• Dietary Supplement Formulation: Used as an active iron ingredient in tablets, capsules, and liquid supplements.
• Food Fortification: Incorporated into cereals, flour, and nutritional beverage powders to enhance iron content.
• Pharmaceutical Preparations: Serves as an iron source in prescription and over-the-counter medications for treating anemia.
• Animal Feed Additive: Utilized in premixes to prevent iron deficiency in livestock and poultry.
• Clinical Nutrition: A component in enteral and parenteral nutrition formulas for patients with specific dietary needs.
