Quantitative relations between baseline iron status , study duration , and iron dose on changes in iron-status biomarkers , which were generated from the meta-analyses , can be used to predict effects of trials of iron supplementation and fortification and to design iron-intervention programs
BACKGROUND The response of status biomarkers to an increase in iron supply depends on several physiologic and environmental factors , which make it difficult to predict the outcome of an intervention .
OBJECTIVE We assessed effects of baseline iron status , sex , menopausal status , duration of intervention , iron form , and daily dose on the change in iron status in response to iron supplementation .
Evaluation of iron supplements in prevention of iron-deficiency anaemia.
Abstract In many countries an attempt is made at a national level to prevent iron deficiency by enriching food with iron . The amount by which iron intake should be increased is unknown , and decisions seem to be based on very inadequate evidence . Trials of iron supplements in two at-risk groups revealed an effect on haemoglobin level of a supplement of 10 mg . iron per day , but gave no clear evidence of an effect of a smaller supplement
