welche vitamine bei erschöpfung — what symptoms are typical?

Exhaustion can stem from many causes, including vitamin deficiencies. Typical symptoms of B-vitamin deficiency (B12, B6, folate) include persistent fatigue, poor concentration, irritability, and pale skin. Vitamin D deficiency often presents with muscle weakness and bone pain, while iron deficiency (though a mineral) causes fatigue, shortness of breath, and pallor. Evidence for these links is moderate: studies confirm that deficiencies can trigger such symptoms, but exhaustion is non-specific. DNA tests (e.g., MyBody-X) can reveal genetic predispositions for B-vitamin metabolism (e.g., MTHFR variants), but they do not replace blood tests. Effect sizes are small, and clinical validation is limited. Caution: self-supplementation without diagnosis carries risks (e.g., B12 overdose). For persistent exhaustion, a doctor visit with a blood panel is recommended.
