Background: Calcium is the only reported dietary inhibitor of both heme-and nonheme-iron
absorption. It has been proposed that the 2 forms of iron enter a common pool in the …

Background: Quantitative data on the mucosal uptake and serosal transfer of nonheme-iron
absorption in humans and the effects of calcium on these components are limited. Objective …

We investigated the effect of calcium on iron absorption in 126 human subjects. Addition of
calcium chloride to wheat rolls significantly reduced iron absorption. Doses between 40 and …

Calcium is the only known component in the diet that may affect absorption of both nonheme
and heme iron. However, the evidence for a calcium effect on iron absorption mainly comes …

The short-term effect of calcium supplements (1200 mg Ca/d) on daily nonheme-iron
absorption was measured in 14 healthy adult volunteers by using stable isotope extrinsic …

Recent studies based on radioiron measurements from single meals have suggested that
calcium has a strongly inhibitory influence on nonheme-iron absorption. In view of evidence …

The experimental and epidemiological evidence demonstrating that Ca inhibits Fe
absorption was reviewed, with the objectives of estimating the potential impact of variations …

Iron absorption is frequently studied experimentally in animals by placing iron directly into
tied-off intestinal segments in vivo, usually in acid solutions. We have monitored the …

We investigated the inhibitory effect of calcium on iron absorption in 57 human subjects.
Three studies suggested that the effect is not located in the gastrointestinal tract. The …

Iron deficiency is widely observed worldwide, yet, paradoxically, iron is the most plentiful
heavy metal in the earth's crust. Although absorption of iron from the gastrointestinal tract is …
