FUT2 kodiert für eine Fucosyltransferase, die die Sekretion von ABO-Blutgruppenantigenen in Körperflüssigkeiten steuert und mit der Darmmikrobiota assoziiert ist. Einige Studien zeigen schwache Zusammenhänge zwischen FUT2-Varianten und der Aufnahme von Vitamin B12 oder der Anfälligkeit für bestimmte Infektionen – jedoch nicht mit der Menopause.

Direkte-to-Consumer-Tests, die FUT2 mit Menopause-Symptomen verknüpfen, beruhen auf spekulativen oder übertriebenen Interpretationen. Fazit: Es handelt sich um einen Mythos ohne belastbare Evidenz.

A common myth is that B12 deficiency only affects vegans. In reality, absorption declines with age, and many menopausal women have reduced stomach acid (atrophic gastritis), impairing B12 uptake. Another myth: B12 supplements relieve menopause symptoms like hot flashes or mood swings. Evidence is weak – B12 is crucial for nerve function and red blood cells, but a direct effect on menopausal symptoms is unproven unless a deficiency exists. Fact: B12 deficiency can cause fatigue, brain fog, and low mood, which may be mistaken for menopause symptoms. Testing (holotranscobalamin, MMA) is advisable before supplementing. Consumer DNA tests for B12-related genes (e.g., MTHFR, FUT2) have limited predictive value. High-dose B12 is generally safe but unnecessary if levels are normal. Evidence: human-moderate – studies exist on B12 and aging, but few specifically on menopause. Beware of marketing that promotes B12 as a menopause miracle.","area":"gesundheit","canonical_id":"gesundheit:canonical-7d653b62e7d344220348afbe","id":"public-255b212405a27ebb1b33d746","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Myths vs facts: B12 and Wechseljahre","score":27.35777717,"snippet":"Myths vs facts: B12 and menopause.
