JECFA Evaluation
IRON | 1983 | For iron oxides and ferric hydroxide (substances which are virtually non-absorbable sources of iron), there is a wide margin of safety between the amounts of nutritionally required iron and levels of this form of iron that may contaminate food. In the case of ionisable salts, iron from ferric salts is less well absorbed than from ferrous salts (approximately two- to threefold), and c
