What to watch with Ferritin Eisenmangel and Schlaf?

When dealing with low ferritin (iron deficiency) and sleep issues, watch for: Iron deficiency is linked to Restless Legs Syndrome (RLS), which disrupts sleep. It can also cause fatigue and poor sleep quality due to reduced oxygen transport. Test ferritin, transferrin saturation, and hemoglobin – ferritin alone is misleading because it rises with inflammation. If deficiency is confirmed, iron supplementation (e.g., iron bisglycinate) often improves sleep. Caution: supplementing without deficiency risks iron overload. Genetic variants (MTHFR, HFE) may affect iron metabolism but their role in sleep is unclear. Always consult a doctor. Evidence: moderate, based on observational studies and clinical practice.
