About fish oil supplements

Fish oil supplements are a complementary medicine used by many Australians.

Fish oil supplements contain omega-3 fatty acids, which are important nutrients that our body needs for growth, development, building and repair. Omega-3 fatty acids are found in many foods, including oily fish, lean grass-fed red meat, poultry, omega-3 enriched eggs, fortified bread and milk, as well as certain plant and nut oils (eg, flaxseed, linseed, canola, walnut).

Fish oil supplements may be useful if you are not getting enough omega-3 fatty acids from your diet. They may also be recommended if you have certain health conditions such as high blood triglycerides or rheumatoid arthritis.

For some health conditions the clinical evidence is mixed or has changed over time, so possible benefits from taking fish oil supplements are still unclear.

Fish oil supplements do not have many known side effects. However, high doses of fish oil supplements may interact with medicines used to reduce blood clotting, which can make bruising and bleeding more likely.

For health professionals  

Fish oil supplements contain high doses of the long-chain omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

They may be useful for people who cannot meet the dietary recommendations for fish intake, as well as for some people with hypertriglyceridaemia or rheumatoid arthritis.

Recent systematic reviews have questioned the cardiovascular benefits of fish oil supplements beyond hypertriglyceridaemia.
