Zöliakie Test: which supplements make sense?

A celiac test (e.g., MyBody-X DNA test) is a screening tool, not a diagnostic. If celiac disease is confirmed or strongly suspected, malabsorption can lead to deficiencies. Evidence-based supplements include: iron (if ferritin low), vitamin B12, folate, vitamin D, calcium, and zinc – but only after blood work and medical guidance. All supplements must be gluten-free. Enzyme products claiming to break down gluten lack clinical proof. Caveat: Do not self-supplement without a confirmed diagnosis; excess iron or zinc can cause harm. For children, pediatric supervision is essential. Evidence: practice for supplement use in celiac; marketing for the test as screening.
