Used as an iron supplement in pharmaceuticals and nutritional products to treat or prevent iron deficiency anemia. It serves as a source of bioavailable iron in oral formulations due to its relatively good solubility and stability. Also employed in cell culture media as an iron source for supporting microbial or mammalian cell growth. In some cases, it is used in analytical chemistry as a reagent for detecting or quantifying certain compounds. Its chelated form helps reduce gastrointestinal irritation compared to other iron salts, making it suitable for sensitive individuals.
