Can Ferritin Eisenmangel help with Müdigkeit?

The question is ambiguous: 'Ferritin Eisenmangel' (iron deficiency) does not help with fatigue – it causes it. Ferritin is the iron storage protein; low levels indicate depleted iron reserves. Iron deficiency, even without anemia, impairs oxygen transport and mitochondrial ATP production, leading to persistent tiredness. Strong clinical evidence shows that iron supplementation in confirmed deficiency significantly reduces fatigue, especially in menstruating women, athletes, and individuals with blood loss. However, self-supplementation without testing is dangerous: excess iron promotes oxidative stress and organ damage. The evidence is human-strong, but only under medical supervision. Genetic variants like NQO1 rs1800566 are unrelated to iron status. If you suffer from chronic fatigue, measure ferritin, transferrin saturation, and complete blood count, and consult a physician to identify the root cause.
