Nutrition is one of the major determinants aimed at contributing to improving the health status of the population. In Morocco, anemia is public health problem among women (36 %). Two independent studies were conducted. One on the effectiveness of the consumption of fortified flour with elemental iron. Another on the efficiency of the consumption of fortified flour with NaFeEDTA. To compare the efficiency of consumption of fortified flour with elemental iron with the efficiency of the consumption of fortified flour with NaFeEDTA on the iron status of women of childbearing age. In the first study women consumed a test meal composed from fortified bread fortified with Na57FeEDTA plus water. Iron absorption was measured by the erythrocyte incorporation of 57Fe labels after 14 days. In the second study, after 4 years of fortification of elemental iron flour, we determined the prevalence of iron deficiency Efficacy study with flour fortified with NaFeEDTA showed a bioavailability of 33.9% in anemic women and a bioavailability of 16.9% in non-anemic women. NaFeEDTA has a high bioavailability especially among anemic women. The Efficacy study with flour fortified with elemental iron showed no change in iron status of women of childbearing age. The Moroccan government has decided to replace elemental iron with NaFeEDTA in wheat flour to combat iron deficiency.
