What is the recommended dosage for Iron?

General: 8-18 mg/day; Deficiency: Per medical guidance based on ferritin levels

What are the side effects of Iron?

Potential side effects include: Constipation (most common), Nausea and stomach cramps, Dark or black stools, Iron overload with excessive supplementation (hemochromatosis risk).

What is iron's role in immune function?

Iron is an essential mineral required for immune cell proliferation and maturation, particularly T-cells and macrophages. Iron deficiency is associated with impaired immune responses, while iron overload can promote oxidative stress and pathogen growth.

What dosage of iron has been studied for immune-related outcomes?

Iron supplementation doses vary widely depending on deficiency status. For adults with iron deficiency, doses of 30–65 mg of elemental iron per day are common. Supplementation should be guided by serum ferritin and iron studies, not taken empirically.

What are the potential side effects of iron supplementation?

Common side effects include constipation, nausea, stomach pain, and dark stools. Excess iron can be harmful, particularly for individuals with hemochromatosis. Iron supplements should only be taken when a deficiency has been confirmed by blood testing.

About

Iron is essential for immune cell proliferation and maturation, particularly lymphocytes, and is required for the generation of reactive oxygen species by neutrophils to destroy pathogens. Iron deficiency is the most common micronutrient deficiency worldwide and significantly impairs immune cell function. Supplementation should be guided by documented deficiency, as excess iron may feed pathogens.

How It Works

Essential for immune cell proliferation and maturation; required for generation of reactive oxygen species by neutrophils to destroy pathogens; supports oxygen transport to immune tissues.
