What to watch with Omega-3 Index and Allergie?

The Omega-3 Index (percentage of EPA+DHA in red blood cells) is a biomarker for inflammation regulation and cardiovascular health. Regarding allergies, some evidence suggests that higher omega-3 intake may modulate immune responses—e.g., via altered prostaglandin and leukotriene production. However, the evidence is mixed: observational studies sometimes link a low Omega-3 Index to higher allergy risk (hay fever, asthma), but randomized controlled trials often fail to show clear clinical improvement with supplementation. The Omega-3 Index is not an allergy test and does not replace specific IgE diagnostics. If you measure your index (target 8–11%), interpret results in the context of overall diet and inflammatory status. Caveat: High-dose omega-3 can affect blood clotting; no major interactions with allergy medications are known, but medical consultation is advised. Evidence: moderate, based on epidemiological and mechanistic studies.
