Fish oil, rich in omega-3 fatty acids (EPA and DHA), has scientific evidence supporting its use in improving poor circulation and cardiovascular health. Numerous clinical studies suggest that omega-3s can lower triglyceride levels, reduce blood pressure, and decrease platelet aggregation, thereby improving blood flow. These effects are particularly relevant for people at risk of cardiovascular diseases or those with metabolic syndrome, which often involves poor circulation. The American Heart Association recommends fish oil supplementation for certain individuals with high triglycerides, and some guidelines note potential benefits for overall vascular health.

However, while fish oil's general cardiovascular benefits are well documented, its specific role in treating or substantially improving symptoms of "poor circulation" (such as peripheral artery disease or chronic venous insufficiency) is less robustly proven. Some studies indicate improvements in endothelial function and reduced inflammation, which may help circulation, but results are mixed and often modest. Most evidence supports fish oil as an adjunct to other therapies, not as a primary treatment for circulation issues.

In summary, fish oil is scientifically validated for promoting heart and vascular health, and there is moderate evidence (rating: 3/5) supporting its use as part of a strategy to improve poor circulation, especially when related to cardiovascular risk factors. However, it should not be viewed as a standalone treatment for severe circulatory problems.
