Mössbauer (nuclear gamma-resonance) spectroscopy was used to study various industrial samples of vitamins and dietary supplements containing iron ions, which are used in the anemia treatment. Determination of the iron state (Fe²⁺ or Fe³⁺) in medicaments is important for the pharmaceuticals evaluation quality. The investigated samples contain ferrous fumarate, ferrous gluconiate and ferric diphosphate. ⁵⁷Fe hyperfine parameters of the studied pharmaceuticals indicate that there exist major iron ferrous and ferric compounds. However, Mossbauer spectra of the investigated samples demonstrated the presence of additional ferrous and ferric components, probably related to impurities or to a partially modified main component.
