Why the concentration of iron in men more than women?

The concentration of iron in men is generally higher than in women primarily due to differences in physiology and dietary needs. Men typically have larger blood volumes and muscle mass, requiring more iron for hemoglobin production and muscle function. Additionally, women experience regular iron loss through menstruation, which can lead to lower iron levels. Hormonal differences, particularly related to estrogen, also influence iron metabolism and storage in the body.
