Is Ferritin Eisenmangel useful for Schlaf?

Ferritin is a biomarker for body iron stores. Low ferritin (iron deficiency) is linked to sleep disturbances, especially restless legs syndrome (RLS). Human studies indicate that ferritin below 50–75 µg/L increases RLS risk and impairs sleep quality. However, ferritin alone is not a comprehensive sleep diagnostic; sleep issues can stem from apnea, stress, or circadian disorders. The evidence for iron deficiency affecting sleep is moderate – supported by human observational studies but lacking large RCTs validating ferritin as a standalone sleep predictor. MyBody-X offers ferritin testing, but results should be interpreted by a healthcare professional before supplementation. Caveat: Normal ferritin does not rule out other sleep disorders.
