Administration of iron to adult rats did not alter δ-aminolevulinic acid synthetase activity and had little inductive effect on heme oxygenase activity. Both heme and cobalt/dextran rapidly induced microsomal heme oxygenase by 3–8 fold. Induction of heme oxygenase by heme could be totally blocked...
Enhancers of Iron Absorption: Ascorbic Acid and other Organic Acids Ascorbic acid (AA), with its reducing and chelating properties, is the most efficient enhancer of non-heme iron absorption when its stability in the food v... Teucher,Olivares,Cori - 《International Journal for Vitamin & Nutrit...
Iron.Men need around eight milligrams of iron per day while women need significantly more — around 18 if they are menstruating and 27 milligrams if they are pregnant. Bear meat, when safely prepared, offers a great source of heme, or animal-based, iron, which is the type that is the ea...

IronAbsorptionCompetitionNS). We reported evidence that heme and non-heme iron as ferrous sulfate does not compete for absorption. The mechanism behind the absorption of these iron sources is not clear.doi:10.1007/s12011-012-9496-4Diego Gaitán...
These results suggest that the inhibitory effects of bioactive polyphenolic compounds on heme iron absorption cannot be offset by ascorbic acid.doi:10.1096/fasebj.24.1_supplement.208.7Qianyi MaNutritional SciencesPennsylvania State UniversityUniversity ParkPAEun-Young Kim...
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 from studies that did not isolate the effect of calcium from that of other dietary components, because it was ...

Administration of iron supplements (due to incomplete absorption of around 20%) increases colonic iron, leading to adverse effects and altering the microbiota. In vitro and in vivo studies proposed that through oral iron, the beneficial barrier of commensal gut bacteria is decreased and the abundance...
