was ist ein guter hämoglobinwert — what can you do yourself?

A good hemoglobin level depends on age, sex, and individual factors. For adult men, 13.5–17.5 g/dL is normal; for non-pregnant women, 12.0–15.5 g/dL. Values below indicate anemia, above polycythemia. To support healthy levels yourself, focus on iron-rich foods (red meat, legumes, leafy greens) and adequate vitamin C to enhance iron absorption. Vitamin B12 and folate are also important. Regular exercise can stimulate erythropoiesis. However, persistent low or high values require medical evaluation – genetic variants (e.g., in HBB, HFE) can affect hemoglobin but are rarely the sole cause. Evidence for dietary influence is strong for iron-deficiency anemia, but weaker for supplementation without deficiency. Caveat: self-supplementing iron can be harmful in hemochromatosis.
