Polyunsaturated Fatty Acids (PUFAs) and Thrombosis: Scientific Evidence

Polyunsaturated fatty acids, especially the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have been studied for their potential in supporting cardiovascular health and reducing the risk of thrombosis. Thrombosis, the process of blood clot formation within blood vessels, can lead to serious events such as stroke and myocardial infarction.

Evidence suggests that omega-3 PUFAs exert antithrombotic effects through several mechanisms, including inhibition of platelet aggregation, reduction of blood viscosity, modulation of endothelial function, and reduction of inflammatory mediators. Clinical trials and meta-analyses have demonstrated that omega-3 supplementation can modestly reduce platelet aggregation and some markers of thrombosis, although the effect on clinical outcomes such as heart attack and stroke has been mixed and sometimes controversial.

Major guidelines (e.g., American Heart Association) recognize omega-3 PUFAs as supportive in cardiovascular prevention, but recent large-scale randomized controlled trials (like the ASCEND and VITAL trials) have shown only modest or no benefit in major cardiovascular events, including thrombotic events, in the general population. However, certain patient subgroups and higher-risk individuals may benefit more.

In summary, there is scientific evidence for the use of polyunsaturated fatty acids, especially omega-3s, in supporting antithrombotic mechanisms, rating a 3 out of 5 due to mixed results in clinical outcomes despite robust mechanistic and smaller-scale clinical evidence.
