May improve blood flow

Nitric oxide may be produced by your body from omega-3 lipids found in salmon oil. Nitric oxide encourages blood arteries to relax, which improves blood flow and lowers blood pressure. DHA and EPA, omega-3 fats present in salmon oil, were found to dramatically enhance blood flow and oxygen delivery during exercise in research involving 21 individuals. This was in contrast to those who ingested a different type of oil.

Another small, 6-week trial found that taking daily EPA and DHA supplements increased exercise tolerance and blood flow in participants performing hand-grip exercises compared to a control group. Although these findings are promising, additional research is required to fully comprehend how salmon oil's omega-3 fatty acids might enhance blood flow and athletic performance.
