What should I know about vitamin b 12 mangel symptome frau?

Vitamin B12 deficiency in women can cause fatigue, cognitive issues, anemia, neurological symptoms (tingling, numbness), and mood changes. Risk factors include vegan/vegetarian diet, pregnancy, and use of acid-reducing medications. Diagnosis requires blood tests (holotranscobalamin, methylmalonic acid). Genetic variants like FUT2 may affect absorption but are not diagnostic. Always confirm deficiency with lab results before supplementing. Symptoms are non-specific, so laboratory confirmation is essential.
