However, a Cochrane review of 33 trials in 13,114 children showed that intermittent supplementation does not appear to have this effect [77]. Hemoglobin and hematocrit tests are the most commonly used measures to screen patients for iron deficiency, even though they are neither sensitive nor specific [5,7,17]. If this does not resolve, the next stage is a greater depletion of iron stores and a drop in red blood cells. Food insecurity is associated with iron deficiency anemia in US adolescents. Other forms of supplemental iron, such as heme iron polypeptides, carbonyl iron, iron amino-acid chelates, and polysaccharide-iron complexes, might have fewer gastrointestinal side effects than ferrous or ferric salts [27]. Newer slow-release forms of iron have been introduced, which may help reduce gastrointestinal side effects, but they are more expensive and usually contain less iron.

The effects of organic acids, phytates and polyphenols on the absorption of iron from vegetables. 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.

Marginal deficiency, mild functional deficiency, or iron-deficient erythropoiesis (erythrocyte production): Iron stores are depleted, iron supply to erythropoietic cells and transferrin saturation decline, but hemoglobin levels are usually within the normal range. The U.S. Department of Agricultures (USDAs) FoodData Central [25] lists the nutrient content of many foods and provides a comprehensive list of foods containing iron arranged by nutrient content and by food name. Because proton pump inhibitors, such as lansoprazole (Prevacid) and omeprazole (Prilosec), reduce the acidity of stomach contents, they can reduce iron absorption [3].
