Iron bioavailability and dietary reference values. Web (-)rn. Serum ferritin concentration, a measure of the body's iron stores, is currently the most efficient and cost-effective test for diagnosing iron deficiency [11-13]. Full-term infants usually have sufficient iron stores and need little if any iron from external sources until they are 4 to 6 months old [2]. But when such treatment is not possible, iron supplementation and/or erythropoiesis-stimulating agents (ESAs) are sometimes used. Am J Clin Nutr 2005;82:1024-31.

Iron is a mineral that is naturally present in many foods, added to some food products, and available as a dietary supplement. Acute intakes of more than 20 mg/kg iron (about 1,365 mg iron for a person weighing 150 lb) from supplements or medicines can lead to corrosive necrosis of the intestine, which might lead to fluid and blood loss, shock, tissue damage, and organ failure, especially if food is not taken at the same time as the iron [89]. The American College of Obstetricians and Gynecologists (ACOG) states that good and consistent evidence shows that iron supplementation decreases the prevalence of maternal anemia at delivery [, The Centers for Disease Control and Prevention (CDC) recommends that all pregnant women, at their first prenatal visit, begin taking an oral, low dose (30 mg/day) supplement of iron and be screened for IDA [, In contrast, the U.S. Preventive Services Task Force (USPSTF) has concluded that the current evidence is insufficient to recommend for or against both screening for IDA in pregnant women and routinely supplementing them with iron to prevent adverse maternal health and birth outcomes [, The CDC recommends that infants less than 12 months of age who are not exclusively or primarily breastfed drink iron-fortified infant formula [, The American Academy of Pediatrics recommends 1 mg/kg daily iron supplementation for exclusively or primarily breastfed full-term infants from age 4 months until the infants begin eating iron-containing complementary foods, such as iron-fortified cereals [, The WHO recommends universal supplementation with 2 mg/kg/day of iron in children aged 6 to 23 months whose diet does not include foods fortified with iron or who live in regions (such as developing countries) where anemia prevalence is higher than 40% [, In a recommendation statement issued in 2015, the USPSTF concluded that the available evidence is insufficient to recommend for or against routine screening for IDA in children ages 6 to 24 months who live in the United States and who are asymptomatic for IDA [. Any confusion with iron supplement types and amounts can be resolved by asking your doctor to specify both the elemental amount and the chemical compound amount. Manoguerra AS, Erdman AR, Booze LL, Christianson G, Wax PM, Scharman EJ, et al. The U.S. Food and Drug Administration (FDA) developed DVs to help consumers compare the nutrient contents of foods and dietary supplements within the context of a total diet. The main therapy for anemia of chronic disease is treatment of the underlying disease [79]. Approximately 60% of patients with chronic heart failure have iron deficiency and 17% have IDA, which might be associated with a higher risk of death in this population [59,60].

[, Campbell NR, Hasinoff BB, Stalts H, Rao B, Wong NC. Among 1,106 elderly White adults aged 67 to 96 years in the Framingham Heart Study, 13% had high iron stores (serum ferritin levels higher than 300 mcg/L in men and 200 mcg/L in women), of which only 1% was due to chronic disease [40]. Deficiency (including IDA) is more common among children and adolescents in food-insecure households than in food-secure households [36,37]. Confusion is also caused by two number amounts listed on the label, a higher number and a lower number. Using a principle called reverse rusting, the cells breathe in air, which transforms the iron into iron oxide (aka rust) and produces energy. WebIron is a mineral. Guidelines on iron supplementation during pregnancy vary, but many recommend some form of iron supplementation to prevent IDA: The IOM notes that because the median intake of dietary iron by pregnant women is well below the EAR, pregnant women need iron supplementation [5]. Learn a new word every day. Only a few small studies have evaluated the benefits of oral iron supplementation alone or in combination with ESAs to treat anemia of chronic disease. Having enough iron in the body can help prevent iron deficiency and iron deficiency anemia. Low intakes also increase her infants risk of low birthweight, premature birth, low iron stores, and impaired cognitive and behavioral development. For younger ages, the UL is 40 mg. Meats, poultry, and seafood are richest in heme iron. 2017 Dec;106(Suppl 6):1626S-33S. Because proton pump inhibitors, such as lansoprazole (Prevacid) and omeprazole (Prilosec), reduce the acidity of stomach contents, they can reduce iron absorption [3]. [, Butte NF, Fox MK, Briefel RR, Siega-Riz AM, Dwyer JT, Deming DM, et al. Pediatrics 2015;136:746-52. IDA: Iron stores are exhausted; hematocrit and levels of hemoglobin decline; and the resulting microcytic, hypochromic anemia is characterized by small red blood cells with low hemoglobin concentrations. Some people have a hereditary condition called hemochromatosis that causes an excessive buildup of iron in the body. Guidelines vary on dietary iron intakes and possible supplementation to ensure adequate iron status and to prevent or treat IDA in infants and young children: Some studies have suggested that iron supplementation in young children living in areas where malaria is endemic could increase their risk of malaria [75,76]. Multivitamin/multimineral supplements with iron, especially those designed for women, typically provide 18 mg iron (100% of the DV). If left untreated, iron can build up in certain organs so that there is a higher risk of developing conditions like liver cirrhosis, liver cancer, or heart disease.

However, these indicators are not sensitive or specific enough to adequately describe the full spectrum of iron status, and this can complicate the diagnosis of iron deficiency. Inflammation changes the bodys immune function, preventing the body from being able to use available stored iron to make red blood cells and also causing blood cells to die out more quickly. Mild deficiency or storage iron depletion: Serum ferritin concentrations and levels of iron in bone marrow decrease. The ULs apply to healthy infants, children, and adults.
