Taking fish oil supplements with EPA and DHA might help keep your blood from clotting too easily, which could lower your chance of having a heart attack or stroke if you already have heart disease.

Appropriate Language Strength

Assessment Explanation
The claim uses 'associated with' and 'may lower,' which correctly reflect observational and mechanistic evidence without asserting causation. This is appropriate because while RCTs show EPA/DHA reduce platelet activity and some cardiovascular events, the direct causal link to arterial thrombosis reduction is inferred from intermediate biomarkers and population studies. The wording avoids overstatement by acknowledging uncertainty.
More Accurate Statement
“Dietary supplementation with eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) is associated with reduced platelet aggregation and thrombus formation, which may contribute to a lower risk of arterial thrombosis in individuals with cardiovascular disease.”

This study shows that EPA and DHA (fish oil components) help protect blood vessels and reduce inflammation, which makes it less likely for blood clots to form — exactly what the claim says.
