Non-haem iron

Non-haem iron is the predominant iron form in plants, but also occurs in meat. It can be found in soluble form, in low-molecular-weight complexes, bound to ferritin or bound to other proteins. This iron form is not tightly sequestered and can therefore be affected by dietary inhibitors that impair its absorption (Anderson & Frazer, 2017).

Synonyms: Non-heme iron, unbound iron
