    Abstract

    Co-supplementation of ferrous salts with vitamin C exacerbates oxidative stress in the
    gastrointestinal tract leading to ulceration in healthy individuals, exacerbation of chronic
    gastrointestinal inflammatory diseases and can lead to cancer. Reactive oxygen and nitrogen
    species (RONS) have been ascribed an important role in oxidative stress. Redox-active metal ions
    such as Fe(II) and Cu(I) further activate RONS and thus perpetuate their damaging effects.
    Ascorbic acid can exert a pro-oxidant effect by its interaction with metal ions via a number of
    established RONS generating systems which are reviewed here. Further studies are required to
    examine the detrimental effects of nutraceuticals especially in chronic inflammatory conditions
    which co-present with anaemia.
