Abstract: A composition comprising an iron salt of a C8 to C24 fatty acid, a citric acid ester of mono- and/or diglyceride or a mixture of citric acid esters of mono-and/or diglycerideand optionally a fatty acid or a mixture of fatty acids, and a method for preparing such a composition. The composition is useful as a medicament for the treatment and prophylaxis of iron deficiency, as a dietary supplement,and as a food additive.

Abstract: In one aspect, there is provided a fluorescent iron-binding compound bound to a solid phase. Also provided is a method for detecting non-transferrin bound iron in a sample, comprising contacting the sample with a fluorescent iron-binding compound bound to a solid phase and detecting a fluorescent signal derived from the fluorescent iron-binding compound bound to the solid phase, wherein the fluorescent signal is indicative of non-transferrin bound iron levels in the sample. Further provided is use of a fluorescent iron-binding compound bound to a solid phase to detect non-transferrin bound iron in a sample.
