Iron supplements help only
certain women who are not anemic
Among women who are not anemic, only those with tissue-iron deficiencies can benefit from
taking iron supplements, concludes a new study by Cornell University nutritionists.
"Supplementation makes no difference
in exercise-training improvements in women with low iron storage who are not yet
tissue-iron deficient or anemic," says Thomas Brownlie, the first author of the study
and a Cornell doctoral candidate in nutritional sciences.
Women with low body iron, but who are not
anemic, may not experience any improvements following training if their tissues are low in
iron. Whereas women who have low iron storage in their liver only, and who are not anemic,
appear to have no functional impairments.
