Zinc and iron play complementary roles in heme synthesis, absorption, transport and bioavailability of iron. Supplementation programs combining both minerals can yield favorable biochemical and morbidity outcomes; however, evidence surrounding their interaction is insufficient to support policies recommending their combined supplementation.

An anemic pregnant women randomized trial conducted in Ghana evaluated the impact of iron and zinc supplements on Hb and serum ferritin levels.
Deficiency
Iron and zinc are essential trace minerals for human health, involved in metabolic processes involving glucose, proteins, and nucleic acids. Zinc deficiency causes anemia which is treatable through oral supplements and symptoms include fatigue, weakness, poor appetite, brittle nails and hair loss. Zinc also plays an integral role in iron absorption, metabolism, and transport.
Studies on suckling rats have demonstrated that zinc supplementation increases DMT1 mRNA expression and FPN1 protein expression to facilitate iron absorption via IRP2-dependent activation of PI3K signaling. Furthermore, studies conducted with human intestinal cell lines demonstrate how zinc modulates iron absorption by increasing basolateral exit of minerals and inhibiting DMT1.
Humans suffering from low serum iron levels may experience fatigue, headaches, and abdominal cramping symptoms as a result. Individuals affected by iron deficiency also often exhibit heart symptoms like tachycardia and chest pain, as well as cognitive deficits and increased risks for cardiovascular diseases and infections; fortunately, combining iron and zinc supplements may be effective at relieving symptoms associated with iron deficiency anemia.
Supplements
Iron is essential in supporting healthy red blood cell formation, while zinc contributes to maintaining an effective immune system, both essential nutrients required by our bodies for many bodily processes. Supplements combining iron and zinc may improve absorption rates – for maximum effectiveness, it would be best if taken early morning followed by later in the day for maximum benefit.
Studies have demonstrated the efficacy of iron supplementation for anemia and iron deficiency. Some research indicates that combined iron-zinc supplementation may be more effective than taking iron alone, though other research suggests these substances interact negatively in terms of absorption and metabolism.
As zinc and iron compete for the same receptor in your gut, they may impede each other’s bioavailability – an effect that lasts approximately 30 minutes or less. According to one study, when both vitamins were administered simultaneously in an aqueous solution. The inhibitory effect lasted 30 minutes or less.
915 breast-fed infants living in Que Vo’s rural district were randomly divided into three groups for this randomized controlled trial; Fe received daily iron supplementation for six months, Zn received 10 mg of zinc daily, while Fe+Zn infants received both iron and 10 mg of zinc dietary intake was tracked with semi-quantitative food frequency questionnaire, while hemoglobin (Hb), serum ferritin and CRP levels were taken before and after supplementation.
Combination
Iron and zinc are vital micronutrients whose deficiencies remain a significant health problem in many populations. Supplementing with individual micronutrients improves specific biochemical and functional outcomes while combined iron-zinc supplements may interfere with each other’s absorption; to minimize interference it is therefore recommended to take them separately at different times or doses.
Instead of iron being controlled by its absorption and metabolism through diet or supplements, zinc homeostasis is maintained through controlling endogenous secretions that excrete into the intestine where they combine with enteric iron to form an insoluble chelate that’s then transported through to blood stream via ziynin enzyme.
Zinc has been shown to block the activation of PI3K, an enzyme responsible for controlling iron distribution and concentration within cells. This effect could come either directly through regulation of iron metabolism or indirectly via alteration in cell growth rate that zinc regulates.
Due to these inhibitory effects, short-term trials suggest that adding zinc supplementation does not negatively influence hematological parameters; instead, in children at risk of nutritional deficiencies, zinc may influence iron status positively. Longer term trials must confirm these findings – for this purpose a study was conducted where children with iron deficiency anemia were randomly assigned either an iron-zinc combination therapy or iron sulfate alone for one month; laboratory parameters including CBC, TIBC and serum iron and ferritin levels were then measured both before starting and at its conclusion.
Benefits
Iron and zinc are essential micronutrients that serve a range of crucial functions in the body, from hormone production (mainly male hormones) through enzyme activity, immune support, wound healing, and wound care. Anemia caused by low red blood cell production or inadequate iron intake affects up to one third of humanity; more frequently among women and children during pregnancy as well as vegetarians, people with celiac sprue disease, blood donors or those suffering from digestive conditions like Crohn’s disease [1].
A study conducted in Ghana demonstrated that supplementing with both iron and zinc significantly raised mean hemoglobin concentrations more effectively than taking just iron alone, particularly among women who were iron deficient (with serum ferritin levels below 20 ug/L at recruitment).
Dietary iron and zinc play an integral part in maintaining adequate levels of both minerals, but their absorption depends on other factors as well. Foods high in phytic acid and polyphenols chelate iron and zinc, limiting their availability and absorption; by contrast, foods rich in ascorbic acid or fermentable fiber such as legumes increase availability and absorption.
Zinc and iron may both play a part in inhibiting one another’s absorption by competing during intestinal absorption. Studies have indicated that iron inhibits zinc absorption at 2:1 ratio or greater; however, such inhibition may be reversed when reduced to 1:2 or less ratio.
