What role does Transferrin play in Müdigkeit?

Transferrin is an iron-transport protein in the blood. Its concentration or saturation is used to assess iron status. Low iron levels (iron deficiency) are a common cause of fatigue because iron is essential for oxygen delivery and energy production. Elevated transferrin (with low saturation) can indicate iron deficiency, while low transferrin may point to iron overload or chronic inflammation. However, transferrin is not a direct fatigue marker; fatigue is multifactorial. The evidence linking iron deficiency to fatigue is strong (numerous clinical studies), but interpreting transferrin values requires medical context. Caveat: individual assessment is needed, as other factors (sleep, stress, thyroid) also contribute. MyBody-X tests can measure transferrin, but clinical relevance should be discussed with a physician.
