IgE Allergietest: which supplements make sense?

Based on the provided context, there is no direct information about supplements for IgE allergy tests. The context covers DNA variants, sleep, and product features, but not allergy-specific supplementation. In general, IgE tests indicate sensitization, not necessarily clinical allergy. Common supplements like quercetin, vitamin C, omega-3 fatty acids, and probiotics are often promoted for allergies, but the evidence is limited. Quercetin has mechanistic support as a mast cell stabilizer, but human trials show modest effects. Vitamin C may have antihistamine properties, but data are inconsistent. Probiotics may benefit certain allergic conditions but are not a substitute for standard care. Omega-3s have anti-inflammatory effects, yet evidence for IgE-mediated allergies is weak. Crucially, supplements should not replace proven treatments (antihistamines, corticosteroids, allergen avoidance). Always consult an allergist before starting supplements. The evidence level for these supplements is 'mechanistic' to 'unclear'. No sources in the context address this question directly.
