Low ferritin (<30 µg/L) indicates iron deficiency, even if hemoglobin is still normal (latent deficiency). Fatigue is a common but non-specific symptom of iron deficiency because iron is critical for oxygen transport and cellular energy metabolism. The evidence is human-strong: multiple clinical trials and meta-analyses show that iron supplementation significantly reduces fatigue in iron-deficient individuals. However, ferritin must be interpreted with caution – inflammation (elevated CRP) can falsely elevate ferritin levels. A full iron panel including hemoglobin, transferrin saturation, and CRP is recommended. MyBody-X does not measure ferritin; this requires clinical lab testing. Caveat: self-supplementation with iron without proper diagnosis can be harmful in conditions like hemochromatosis or chronic inflammation. Persistent fatigue warrants a medical workup.","area":"gesundheit","canonical_id":"gesundheit:canonical-cd8b606cc37c93fd9db8a143","id":"public-0fbd891574efe09c4119f354","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: Ferritin Eisenmangel in the context of Müdigkeit","score":26.06760895,"snippet":"Ferritin is a key storage protein for iron and a well-established biomarker for body iron reserves.

Low ferritin indicates depleted iron stores, which can lead to anemia, fatigue, and impaired mitochondrial function – all factors that may negatively impact healthy lifespan. However, direct causal evidence linking ferritin deficiency to longevity is limited. Epidemiological studies show a U-shaped relationship: both iron deficiency and iron overload (elevated ferritin) are associated with increased mortality, with overload often more strongly linked to oxidative stress and chronic disease. For longevity, a balanced iron status appears optimal. Ferritin measurement is clinically established, but interpretation requires context (inflammation, liver function, transferrin saturation).

In menopause, iron deficiency can occur, especially due to heavy or irregular bleeding. However, ferritin is an acute-phase reactant; it can be falsely elevated during inflammation, masking a true deficiency. Therefore, diagnosis should rely on multiple parameters (e.g., transferrin saturation, hemoglobin, CRP). Genetic tests for iron deficiency (e.g., HFE, TMPRSS6) have only moderate evidence and are not recommended in routine clinical practice. Guidelines suggest measuring ferritin in menopausal women with symptoms like fatigue or poor concentration, but interpretation requires clinical context. A standalone DNA test for 'iron deficiency risk variants' is insufficient to justify therapy (e.g., iron supplementation). The evidence for the utility of such tests in menopause is weak to moderate. Caveat: ferritin levels below 30 µg/L indicate iron deficiency, but reference ranges vary. If iron deficiency is suspected, consult a physician before taking supplements.","area":"gesundheit","canonical_id":"gesundheit:canonical-d744d7148de507bce5b4251b","id":"public-91a24fef9ad9889d0ac6f024","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: Ferritin Eisenmangel in the context of menopause","score":25.22933928,"snippet":"Ferritin is a key biomarker for iron stores.

Ferritin is an acute-phase reactant: low levels indicate iron deficiency, but high levels can also result from inflammation (e.g., in metabolic syndrome). Some studies suggest that iron deficiency may impair insulin sensitivity because iron is required for mitochondrial function and enzymes involved in glucose metabolism. However, the evidence is inconsistent: some research finds no clear link, while others report an association between low ferritin and impaired glucose tolerance. Additionally, iron deficiency can cause fatigue and reduced physical activity, indirectly affecting blood sugar. Importantly, ferritin alone is insufficient to assess iron status; transferrin saturation and CRP should be measured. The provided context does not contain direct studies on ferritin and blood sugar. Therefore, this assessment is based on general medical knowledge. Evidence grade: mixed/unclear.

Ferritin is a biomarker for the body's iron reserves. Iron deficiency (low ferritin) can contribute to pale, dry skin, increased wrinkling, and impaired wound healing, as iron is essential for collagen synthesis and cellular respiration. However, the evidence for a direct causal link between ferritin levels and skin aging in humans is limited. Most data come from observational studies or mechanistic work. Some studies suggest that iron deficiency can weaken the skin barrier and promote oxidative stress, potentially accelerating skin aging. Conversely, high ferritin (iron overload) can also be harmful due to iron's pro-oxidant effects. Consumer lab tests for ferritin are common, but interpretation should always be in a clinical context (e.g., inflammation markers, CRP). Without medical evaluation, a single ferritin value can be misleading. The evidence base is rated as 'unclear' because no high-quality RCTs or meta-analyses specifically address ferritin and skin aging. Recommendation: If iron deficiency is suspected (fatigue, pallor, hair loss), a physician should order a complete blood count and ferritin, not just a DTC test.","area":"gesundheit","canonical_id":"gesundheit:canonical-5c1401dab1e1ee5743faa386","id":"public-81ec8a0a5c861516336527d3","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: Ferritin Eisenmangel in the context of skin aging","score":24.67940996,"snippet":"The question of ferritin (iron stores) in the context of skin aging is not directly addressed in the provided contexts.
