Eicosapentaenoic acid (EPA) is an omega-3 polyunsaturated fatty acid found primarily in fish oils. Its use for supporting "poor circulation" is primarily based on scientific evidence regarding its effects on cardiovascular health and vascular function. EPA has been shown in multiple clinical studies to reduce triglyceride levels, decrease platelet aggregation, and exhibit anti-inflammatory effects, all of which can positively affect blood flow and vascular health. Meta-analyses indicate that EPA supplementation can lower the risk of major cardiovascular events, especially in high-risk populations. Additionally, EPA may improve endothelial function, which is critical for maintaining proper circulation, by increasing nitric oxide production and reducing oxidative stress in blood vessels.

However, while EPA’s benefits for cardiovascular health are well established, direct evidence for its use specifically in treating “poor circulation” (such as peripheral artery disease or chronic venous insufficiency) is more limited. The available clinical trials more often focus on endpoints like reduced risk of heart attack or stroke rather than direct improvements in peripheral circulation. Nonetheless, the mechanistic rationale and supportive data for improved vascular health make EPA a reasonable adjunct for individuals with compromised circulation, although it should not replace established treatments for circulatory disorders.

In summary, the use of EPA for supporting circulation is scientifically justified, with moderate evidence supporting its role in improving vascular function and reducing cardiovascular risk factors, but more direct studies on poor circulation are needed.
