Fish oil has many uses, it is derived form the bodies, (flesh skin and other parts of the fish. Fish oil is collection of mono and poly unstaurated fats and is liquid at standard room temperature and cold sea temperatures. It does not solidify at these temperatures as do staurated fats derived from animals that live on the land. This is probabaly the reason why fish evolved to use these types of fats. Of particular interest is the specific n3-polyunstaurated fat group. This are produced n all animals from the essential fat alpha linolenic acid or ALA. ALA is an esential fat as only sourced from outside an animal body. From ALA the other omega three fats are derived through complex metabolic processes. The two omega three fats which are of interest to human nutrition and health are EPA (Eicosapentaenic acid) and DHA (Docosahexanoic Acid). These two fats have shown to very beneficla to human health and in particular when taken as a supplement to the western diet they have have been used to intervene in medical diseases.
Fish oil that is rich in omega three fatty acids such as EPA (Eicosapentaenic acid) and DHA (Docosahexanoic Acid) are niow used to support the treatment of depression, pyschiatric disorders, autism, skin disorders, immune dysfunctions, psoriasis, dementia, heart disease, healthy blood fats, high cholesterol, eye health and nerve function.

- 30% omega three standard cheap oil.
- 50% concentrated omega three oil
- 75% concetrated omega three oil.
- 90% omega three oil
- Ethyl Ester omega three oil, (free of the glycerine)
- High EPA oil
- High DHA oil
- Zero DHA oil
- EPA belneded with omega 6 fatty acis such as gamm linolenic acid.
- Pure EPA
- Algal DHA derived from a vegan source (algae)
- Algal High DHA and Low EPA oil.
- And Many Others
Cod liver oil or other fish liver oils does not always become a source of omega 3. You should always check. Seven Seas make a fish liver oil that has omega three enrichment called triomega.
