Zinc inhibits nonheme iron bioavailability in humans

No significant effect of zinc on iron absorption was found at Zn:Fe molar ratios up to 2:1. At 5:1,10:1, and 20:1 molar ratios, a dose-dependent inhibitory effect on iron absorption was observed 28-40% of iron absorption inhibition; one-way repeated-measures ANOVA, F=4.48, p=0.02 . In conclusion, zinc administration combined with iron in an aqueous solution leads to the inhibition of iron bioavailability, …Cited by: 51

Acute inhibition of iron absorption by zinc - ScienceDirect

01.05.2007 & 0183;& 32;Iron and zinc deficiencies are the most common nutritional deficiencies worldwide. Combined zinc and iron supplementation is one of the strategies used to prevent these deficiencies. Zinc has an inhibitory effect on iron absorption. The objective of the study was to determine the duration of the inhibitory effect of zinc on iron absorption.Cited by: 15

Inhibition of zinc absorption by iron depends on their ...

01.01.2001 & 0183;& 32;Our results showed that when both minerals are given as solutes, iron did not impair zinc absorption up to a iron:zinc ratio of 2:1; then a dose- dependent effect was observed up to a ratio of 5 : 1; when the ratio was increased from 5:1 to 10:1, no further inhi- bition of zinc occurred. In addition an acute iron deficiency exacerbated the inhibition of iron on zinc absorption. Previous experimental studies support our results: in mice the inhibition of intestinal transfer of zinc ...Cited by: 30

Iron and Zinc Nutrition in the Economically-Developed ...

13.08.2013 & 0183;& 32;Despite claims that certain compounds inhibit and enhance absorption of both iron and zinc, there is insufficient evidence reflecting free-living populations to derive dietary recommendations, particularly in the case of zinc. Single-meal absorption studies have demonstrated that phytate, polyphenols in beverages, supplemental calcium and soy protein can inhibit iron absorption. Of these potential inhibitors, phytate and soy protein have been shown to also inhibit zinc absorption ...位置: 8600 Rockville Pike, Bethesda, MD

At 5:1,10:1, and 20 :1 molar ratios, a dose-dependent inhibitory effect on iron absorption was observed 28-40% of iron absorption inhibition; one-way repeated-measures ANOVA, F = 4.48, p = 0.02 . In conclusion, zinc administration combined with iron in an aqueous solution leads to the inhibition of iron bioavailability, which occurs in a dose ...

Zinc inhibits oxidative stress-induced iron signaling and ...

Apr 01, 2010 & 0183;& 32;A systematic review of iron and zinc supplementation trials in humans also confirms our findings . In the present study we demonstrated that zinc inhibits oxidant-induced IRP1 activation and DMT1 expression, which might explain the possible mechanism of inhibition of iron absorption in the presence of zinc.

Geophagia in Turkey: iron and zinc deficiency, iron and ...

Therefore, malabsorption of iron and zinc was considered to be an additional and/or a new finding in the syndrome. Furthermore, Turkish clay most probably inhibits zinc absorption in a way similar to its inhibition of iron absorption.

Does iron and zinc compete for absorption?

Zinc and iron interact competitively during intestinal absorption.When both nutrients are ingested simultaneously in aqueous solutions at levels commonly used in supplements, there is evidence that an excess of iron inhibits zinc absorption 1,2 and that excess zinc inhibits iron uptake 3 .

Zinc inhibits oxidative stress-induced iron signaling and ...

Further, zinc enhanced the Bcl-2/Bax ratio and reduced caspase-3 activity, leading to inhibition of apoptosis. Interestingly, bathophenanthroline disulfonic acid, an extracellular iron chelator, emulated the effects of zinc except for the reduced ferritin levels. These results suggest that zinc inhibits apoptosis by reducing oxidant-induced ...

New Evidence of Iron and Zinc Interplay at the Enterocyte ...

Yamaji et al. examined the absorption of iron 1 μmol/L 55 Fe 2 in the presence of 100 μmol excess zinc and the absorption of zinc 1 μmol/L 65 Zn 2 in the presence of 100 μmol/L iron. Although Fe significantly inhibited the uptake of Zn, the reverse was not true.

Foods That Inhibit Iron Absorption Livestrong.com

Dec 14, 2018 & 0183;& 32;Cocoa and coffee are food sources that can inhibit iron absorption in the body. These foods sources contain polyphenols or phenolic compounds, antioxidants that help remove damaging free-floating cells from the body — which means that morning cup of coffee inhibits iron. According to the Iron Disorders Institute, cocoa can inhibi t 90 percent ...

Apr 29, 2020 & 0183;& 32;Iron inhibits absorption of zinc. Cadmium- toxic levels of cadmium can inhibit zinc absorption; Although Copper in high amounts inhibits Zinc absorption, studies using 15mg zinc combined with 2mg copper showed no inhibition of zinc absorption was found. Metabolics Zinc Formula only contains 2 mg Copper.

Aug 13, 2020 & 0183;& 32;Some minerals influence the absorption of others. For instance, excess zinc in the diet can impair iron and copper absorption. Conversely, certain vitamins enhance mineral absorption. For example, vitamin C boosts iron absorption, and vitamin D boosts calcium and magnesium absorption.

Absorption of Minerals and Metals

A number of nutritional factors have been identified that modulate zinc absorption. Certain animal proteins in the diet enhance zinc absorption. Phytates from dietary plant material including cereal grains, corn, rice chelate zinc and inhibit its absorption.

Zinc, Iron, Vitamin A and Psychosocial Care for Child ...

Dec 18, 2014 & 0183;& 32;Since diets low in iron is usually also low in zinc, zinc deficiency --which has negative consequence on growth-- is common in iron deficiency area. In Southeast Asia, the condition is exacerbated by the rich phytate content in the complementary foods which inhibits the absorption of iron as well as zinc Gibson, 1994 .
