GOTHENBURG, Sweden, Oct. 19, 2026 /PRNewswire/ -- Global dietary data suggest that billions of adults are not getting the daily recommended dose of omega-3 from fatty fish, yet in a crowded supplement market, simply taking omega-3 does not tell anyone where they stand. A new study based on 762,150 blood samples adds large-scale real-world evidence to the value of a test-based approach. People who reported following Zinzino's structured Balance Concept for at least 120 days showed higher omega-3 levels and a more balanced omega-6:3 ratio than both non-users and people taking omega-3 supplements on their own. The findings also show why a broader fatty acid profile matters: omega-3 levels alone do not tell the whole story.
