Can Ferritin help with Schlaf?

Ferritin is an iron storage protein. Low ferritin can indicate iron deficiency, which is associated with sleep disturbances such as restless legs syndrome. However, direct evidence that ferritin supplementation improves sleep is limited. Iron supplementation should only be considered after confirming deficiency via blood tests. Elevated ferritin due to inflammation may also disrupt sleep. The evidence is moderate, based on observational studies linking iron status to sleep quality, but not specifically ferritin as a sleep aid. MyBody-X tests can measure ferritin, but results must be interpreted with a healthcare provider. Without confirmed deficiency, supplementation is not recommended.
