Most of the daily iron requirement is derived from recycling of senescent erythrocytes by macrophages; only 510 % comes from the diet. Iron absorption is affected by inhibitors and enhancers of iron absorption and by the physiological state. Inflammatory conditions, including obesity, can result in ...
The aim of this study was to determine whether women with low iron stores (plasma ferritin ≤ 20 μg/L) receiving a daily iron supplement for 8 wks at a level commonly used to treat poor iron status develop increased lipid peroxidation as measured by ethane exhalation rates and plasma malond...
Iron in excess of this requirement is stored as ferritin and hemosiderin. Unloading of iron to immature erythroid cells is by receptor-mediated endocytosis. The process begins in clathrin-coated pits with the binding of diferric transferrin to specific plasma membrane transferrin receptors. The next ...
The principle of iron conservation is the basis of iron metabolism; the normal basal loss of iron from the body is about 1mg daily in a 70kg man and 0.8mg in a 55 kg woman. Iron is lost mainly by the menstrual and gastrointestinal routes. The total iron requirement during pregnancy is 8...
For example, the monthly menstrual loss in 10% of healthy women is more than 80 ml (average for most women is 30 ml). This increases the daily iron requirement by about 0.8 mg or 6% of the dietary intake. It would be necessary for such an individual to increase her absorption of ...

This is especially crucial for young women planning to conceive, given that a serum ferritin level above 100 μg/L aligns closely with the supplemental iron requirement (approximately 1000 mg) during pregnancy. 3. Markers of iron deficiency 3.1. Routine bio-markers 3.1.1. Serum iron Dietary ...
Purpose: Globally, about 40% of pregnant women have anemia. Pregnant women are at high risk of iron and folic acid deficiency anemia due to increased nutrient requirement during pregnancy. Iron/folic acid supplementation with optimal adherence is the main cost-effective strategy for prevention of ir...
