wieviel eisen bei haarausfall — what can you do yourself?

Iron deficiency is a well-recognized cause of diffuse hair loss (telogen effluvium). Evidence from observational studies shows that supplementation can reverse hair loss if deficiency is confirmed (ferritin < 30–40 ng/mL). However, self-supplementation without testing is not recommended because excess iron can cause oxidative stress. What you can do yourself: 1) Get a blood test for ferritin, hemoglobin, and transferrin saturation. 2) If deficient: take 40–80 mg elemental iron daily (e.g., iron bisglycinate) for 3–6 months, with vitamin C to enhance absorption. 3) Eat iron-rich foods (red meat, legumes, spinach) and avoid coffee/tea with meals. 4) If ferritin is normal, extra iron won't help – investigate other causes (thyroid, stress, hormones). Caveat: Evidence is moderate (observational, not large RCTs); many consumer DNA tests for iron metabolism are not clinically validated.
