Iron in ferritin or in salts (ferrous sulfate) is equally bioavailable in nonanemic women.
BACKGROUND Recent studies in humans suggest that ferritin iron in soybeans has high bioavailability. However, direct evidence for this is lacking because the soybeans were intrinsically labeled; thus, iron bound to other ligands, such as phytate, was also labeled. OBJECTIVE The objectives of the study were to evaluate the absorption of iron from extrinsically labeled, purified ferritin (horse...
متن کاملIron absorption from soybean ferritin in nonanemic women.
BACKGROUND Dietary ferritin, a protein cage around an iron mineral, is an underestimated source of bioavailable iron. Plant ferritin, the most common dietary ferritin, has not been studied. Iron from animal ferritin is absorbed as well as is iron from FeSO4 in women. OBJECTIVE The objective was to examine iron absorption from purified soybean ferritin. DESIGN Healthy, nonanemic women (n = 1...
متن کاملElectrolytic iron or ferrous sulfate increase body iron in women with moderate to low iron stores.
Commercial elemental iron powders (electrolytic and reduced iron), as well as heme iron supplements, were tested for efficacy in improving the iron status of women. In a randomized, double-blind trial, 51 women with moderate to low iron stores received daily for 12 wk: 1) placebo, 2) 5 mg iron as heme iron or 50 mg iron as 3) electrolytic iron, 4) reduced iron, or 5) FeSO(4). Treatments were pr...
متن کاملIntravenous iron for the treatment of fatigue in nonanemic, premenopausal women with low serum ferritin concentration.
This is the first study to investigate the efficacy of intravenous iron in treating fatigue in nonanemic patients with low serum ferritin concentration. In a randomized, double-blinded, placebo-controlled study, 90 premenopausal women presenting with fatigue, serum ferritin ≤ 50 ng/mL, and hemoglobin ≥ 120 g/L were randomized to receive either 800 mg of intravenous iron (III)-hydroxide sucrose ...
متن کاملFerrous Iron Is a Significant Component of Bioavailable Iron in Cystic Fibrosis Airways
UNLABELLED ABSTRACT Chronic, biofilm-like infections by the opportunistic pathogen Pseudomonas aeruginosa are a major cause of mortality in cystic fibrosis (CF) patients. While much is known about P. aeruginosa from laboratory studies, far less is understood about what it experiences in vivo. Iron is an important environmental parameter thought to play a central role in the development and main...
