Iron
Stomach and gut healthIron is an essential trace element involved in the production of hemoglobin and the transport of oxygen in the blood.
In circulation, most iron is bound to the protein transferrin.
Why this matters
Blood iron reflects how much iron is immediately available for critical functions like oxygen transport and energy metabolism. Low levels can cause fatigue, weakness, and poor concentration before anemia develops, while high levels may harm organs. Diet, vitamin C intake, blood loss, and absorption inhibitors like tea or coffee influence iron status. Monitoring helps detect imbalances early so nutritional or medical measures can be taken.
