Cod liver fish oil, a supplement rich in vitamin A, packed in capsules.

Fish oil is oil derived from the tissues of oily fish. Fish oils contain the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), precursors of certain eicosanoids that are known to reduce inflammation in the body, and have other health benefits.[1]

Therapeutic value[]


It is common practice for doctors to prescribe nonsteroidal anti-inflammatory drugs (NSAID) for patients suffering from arthritis. NSAID has the ability to inhibit the enzyme cyclo-oxygenase (COX), from which the prostaglandin E2, responsible for the inflammatory response which gives the athritic pain, is derived. Thus, by blocking COX the inflammation may be kept down. However, NSAID has certain side effects, including increased risk of cardiovascular incidents. Fish oil may be a reasonable substitute for NSAID; it contains a natural inhibitor of COX while at the same time helping to reduce the risk of cardiovascular incidents through multiple mechanisms.[1]
