Zöliakie Glutenunverträglichkeit-Test: which supplements make sense?

The question of which supplements make sense in the context of a celiac disease/gluten intolerance test requires careful distinction. A medically confirmed celiac diagnosis (antibodies + duodenal biopsy) mandates a lifelong strict gluten-free diet. Supplements are only indicated when deficiencies are proven by blood tests (e.g., iron, vitamin B12, folate, vitamin D, calcium) – not based on the test alone. However, many consumer tests (e.g., IgG-based food intolerance panels) lack scientific validation and are not recommended by allergy guidelines. They do not provide a reliable diagnosis and can lead to unnecessary dietary restrictions or supplementation. The provided context contains no specific evidence for supplements in celiac or gluten intolerance. The evidence for such tests is rated as 'marketing'. A responsible approach: seek medical evaluation for suspected celiac disease; if confirmed, consult a dietitian and supplement only based on lab-confirmed deficiencies. Without a confirmed diagnosis, supplements are not indicated and may cause harm (e.g., cost, delayed proper treatment).
