Fish oil is among the most common natural supplement for treatment of hypertriglyceridemia or prevention of cardiovascular disease.
However, concerns about theoretical bleeding risk have led to recommendations that patients should stop taking fish oil before surgery or delay in elective procedures for patients taking fish oil by some healthcare professionals.
The study, published in the journal Circulation, found that higher blood omega-3 levels -- eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) -- were associated with lower risk of bleeding.
The findings showed that there was a significant reduction in the number of units of blood needed for transfusions.
"The researchers in this study concluded that these findings support the need to reconsider current recommendations to stop fish oil or delay procedures for people on fish oil before cardiac surgery," said Bill Harris, Founder of OmegaQuant.
While Omega-3s, specifically EPA and DHA, are important for heart, brain, eye and joint health, most people do not get enough of these valuable fatty acids, which can increase their risk of the most serious health issues.
