Fish oils can be prepared from the livers or bodies of fish, and they are good sources of the unsaturated fatty acids known as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
Fish liver oils, such as cod liver oil, are also rich in vitamin A and vitamin D. Another fat-soluble vitamin, vitamin E, is sometimes added to fish oil supplements.
The unsaturated fatty acids in fish oils, EPA and DHA, belong to a group of fatty acids called the ‘omega-3’ series.
Omega-3 fatty acids are needed for the formation of some types of prostaglandin and other similar substances in the body; these have important regulatory functions and are needed for the maintenance of healthy membranes.
Fish oils may also play a role in…
Heart and circulation
The omega-3 fatty acids, which occur in fish oils, may help to maintain a healthy heart and circulation. Studies have shown that they may have a beneficial effect on the transport of fats around the body.
Brain and eye function
DHA is needed for the development and maintenance of brain and eye function. An adequate intake of vitamin A – also present in fish liver oils – is needed for healthy eyesight.
Joint mobility
Fish oils have traditionally been used to maintain healthy, mobile joints.
