Fish Oil Augments Blood Flow To Muscles During Exercise

Building muscle depends in part on delivery of adequate raw materials to muscle tissue through the blood. A variety of supplements are promoted to enhance blood flow. A recent study tested whether fish oil (EPA and DHA) could enhance blood flow to active muscles during exercise. The amount of dilation and blood flow in response to an exercise stimulus was measured after 6 weeks treatment with EPA (3.2 g/day) and DHA (2.2 g/day). Fish oil significantly improved exercise-induced dilation by nearly two-fold and blood flow by 36%. These results show that chronic use of fish oil improves blood flow to skeletal muscle during exercise. This is another benefit of fish oil to add to the long list of beneficial effects on blood triglycerides, insulin sensitivity, inflammation, and overall risk of heart disease and stroke. In fact, fish oil may be one of the most health-promoting nutrients you can find in food. The evidence is so vast the Federal Drug Administration (FDA) has approved the following health claim for omega fats: "Consumption of omega-3 fatty acids may reduce the risk of coronary heart disease".
