IgG Unverträglichkeitstest: which supplements make sense?

IgG food intolerance tests are often marketed to identify food sensitivities, but they lack robust scientific validation. The IgG antibodies measured typically reflect normal immune exposure, not true intolerance. Therefore, recommending supplements based on such tests is not evidence-based. Instead, a medically supervised elimination diet or validated tests (e.g., lactose breath test) are more appropriate. Supplements like digestive enzymes or probiotics may help in confirmed intolerances, but not based on IgG results. The evidence for IgG testing is weak and marketing-driven. Caveat: self-prescribing supplements without a proper diagnosis can lead to nutrient imbalances or toxicity. Always consult a healthcare professional.
