Myths often claim that high selenium doses cure acne or stop skin aging. In fact, studies show that selenium deficiency may accelerate skin aging, but supplementation beyond requirements provides no additional benefit and can be toxic in excess (selenosis). Evidence for anti-aging effects on skin is mostly mechanistic and observational; robust randomized controlled trials are lacking. MyBody-X tests can measure selenium status in blood and analyze genetic variants (e.g., in GPX1) that affect selenium utilization. The app uses this data for personalized advice, but effects are small. Maintaining adequate selenium is important, but it is not a miracle anti-aging supplement. Caveat: Supplementation only advisable if deficiency is confirmed.","area":"gesundheit","canonical_id":"gesundheit:canonical-ef499de1e3cb9a03a53dda02","id":"public-a4a52d8fc6672aa49f59862b","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Myths vs facts: Selen and skin aging","score":36.13872666,"snippet":"Selenium is an essential trace mineral that acts as a cofactor for selenoproteins like glutathione peroxidases, which can reduce oxidative damage in skin cells.

B. Glutathionperoxidasen) antioxidativ wirkt und theoretisch vor oxidativem Stress in der Haut schützen könnte. Einige Beobachtungsstudien deuten auf einen Zusammenhang zwischen niedrigem Selenstatus und verstärkter Hautalterung hin. Allerdings ist die Evidenzlage begrenzt: Randomisierte kontrollierte Studien zur Selen-Supplementation gegen Hautalterung sind rar und zeigen keine konsistenten Vorteile. Zudem besteht bei Überdosierung das Risiko einer Selenose (Haarausfall, brüchige Nägel, gastrointestinale Symptome). Die Annahme, dass Selenpräparate Hautalterung verhindern oder rückgängig machen können, ist daher eher ein Mythos. Ein ausgeglichener Selenstatus (via Ernährung, z. B. Paranüsse, Fisch) ist sinnvoll, aber eine Supplementation ohne nachgewiesenen Mangel wird nicht empfohlen. Die Evidenz basiert überwiegend auf mechanistischen und Beobachtungsdaten; große Interventionsstudien fehlen. Fazit: Selen ist wichtig für die Hautgesundheit, aber die Behauptung einer Anti-Aging-Wirkung ist nicht ausreichend belegt.","area":"gesundheit","canonical_id":"gesundheit:canonical-508ebbd195fba47d95c461d4","id":"public-4ccc524320349d61e256dd9d","kind":"qa","language":"de","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Myths vs Facts: Selen und skin aging","score":35.95926226,"snippet":"Selen ist ein essenzielles Spurenelement, das als Bestandteil von Selenoproteinen (z.

The scientific evidence for predicting skin aging directly from single DNA variants is weak. For instance, the COL1A1 variant rs1800012 shows a small statistical association with collagen traits, but its clinical significance is minimal – skin aging is far more influenced by UV exposure, lifestyle, diet, and hormones. The GPX1 variant rs1050450 is sometimes linked to antioxidant defense, but supplementation (e.g., selenium) should only be considered after blood level testing. The 28-day plan and recipe book may promote general healthy eating, but they are not personalized based on your DNA. MyBody-X offers DNA-based tests (NutriCare, Longevity), but the claim that such a test can significantly impact skin aging is overstated. Fact: genetics play only a minor role; the major factors are sun protection, not smoking, balanced nutrition, and skincare. Consumers should be cautious when a DNA test is marketed as an 'anti-aging miracle'.","area":"gesundheit","canonical_id":"gesundheit:canonical-1378ca81a0d3b911b4651628","id":"public-5dc2c29ffa1e2b9aaa589321","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Myths vs facts: INFINITY DNA-Test | inkl. 28-Tage-Plan & Rezeptbuch and skin aging","score":33.73321806,"snippet":"The INFINITY DNA-Test combines genetic analysis with a 28-day plan and recipe book, often marketed with claims about skin aging.

B. von MyBody-X) wird oft als personalisierte Lösung für Gewichtsmanagement und Hautalterung beworben. Fakt ist: Einige Genvarianten wie rs8192678 (PPARGC1A) oder GPX1 haben mechanistische Verbindungen zu Mitochondrienfunktion und oxidativem Stress – das ist wissenschaftlich nachvollziehbar. Allerdings ist die klinische Aussagekraft für den Alltag gering. Ein 28-Tage-Plan mit Rezeptbuch ist ein standardisiertes Ernährungsprogramm, das nicht wirklich auf Ihre individuelle Genetik zugeschnitten ist. Die Evidenz für personalisierte Diäten basierend auf solchen Tests ist schwach („mixed evidence“). Zudem unterliegen DNA-Tests in Deutschland dem GenDG und dürfen keine Krankheiten diagnostizieren. Hautalterung wird oft mit FOXO3 und Antioxidantien in Verbindung gebracht, aber ein direkter Nutzen aus dem Test ist nicht belegt. Vorsicht vor übertriebenen Versprechungen: Die meisten Effekte lassen sich durch eine ausgewogene Ernährung und Lebensstil erreichen, unabhängig vom Genotyp. Sicherheitshinweis: Selen-Supplementierung bei GPX1-Varianten kann toxisch sein – nur nach ärztlicher Abklärung.","area":"gesundheit","canonical_id":"gesundheit:canonical-91d3b7f5b152782a00c295d8","id":"public-f9e6c369645917bc2a14ef02","kind":"qa","language":"de","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Myths vs Facts: DNA Stoffwechselanalyse | inkl. 28-Tage-Plan & Rezeptbuch und skin aging","score":33.25470251,"snippet":"Die DNA-Stoffwechselanalyse (z.
