Across multiple cohorts, higher circulating marine omega-3s are associated with lower risk of premature death, including from cardiovascular disease.
Recent analyses highlight DHA in particular, linking higher levels with reductions in all-cause, cardiovascular, and cancer mortality, strengthening the case for tracking status rather than guessing.
While association is not proof of causation, the consistency across biomarker-based studies is striking. Pragmatically, measure your baseline Omega-3 Index, adjust diet and supplementation, then re-test and track alongside lipids, inflammation, and fitness.
