Nowadays, fish oil supplements are recommended for a variety of conditions including hypertriglyceridemia, prophylaxis of migraine, psychological problems, a secondary level of prevention of cardiovascular disease, type 2 diabetes and inflammations such as asthma, gingivitis, inflammatory bowel disease, and rheumatoid arthritis.

The content of omega-3 includes two essential fatty acids (EFA), eicosapentaenoic (EPA) and docosahexaenoic acid (DHA). EFA is not synthesized by the human body and therefore must be consumed in the diet for prevention of deficiency. EPA and DHA in the cod liver oil modulate the functioning of the immune system.
