Fish oil is found in the flesh of cold water oily fish such as salmon, herrings, mackerel, sardines and pilchards. Fish oil is not to be confused with cod liver which has much lower levels of EPA and DHA. Fish oils do not contain vitamins A and D, so larger amounts can be taken without the risk of A & D toxicity.
Fish oils provide omega 3 fatty acids comprising EPA and DHA. The conversion of linolenic acid (from plant sources) to EPA and DHA is reliant on enzymes and may be an inefficient process in some individuals. As a direct source of EPA and DHA, fish oils may offer some advantages over indirect sources such as Flax. Typical fish oil concentrate composition: EPA 18%, DHA 12%
The omega 3 fatty acids in fish oils are needed by the body to produce prostaglandins E3 (PGE3).
What it does
- Cardiovascular Health: EPA from fish oils have an antithrombotic effect, lipid (triglyceride) lowering, reducing blood and plasma viscosity. They inhibit the activity of thromboxane which causes platelets to stick together.
- Cholesterol: Fish oils appear to reduce triglycerides in addition to improving the ratio between HDL and LDL cholesterol.
- Hypertension: Hypertension is one of the major risk factors for heart attack or stroke. Omega 3 fatty acids in fish oils have demonstrated a significant blood pressure lowering effect.
- Crohn’s disease: The anti-inflammatory effects of omega 3 fatty acids may help Crohns symptoms, and because of a beneficial influence on intestinal cell growth, fish-oil supplementation may lead to an increase of the intestinal mucosal surface area, thereby increasing the absorption of nutrients.
- Multiple Sclerosis: Essential fatty acids appear to positively influence the myelin sheath, the protective covering around nerves that becomes damaged in MS. Diets that are rich in fish oils and low in saturated fats from animal produce are recommended for MS sufferers.
- Inflammatory Conditions: Omega 3 fatty acids suppress the production of inflammatory compounds produced by white blood cells. Fish oils are thought to be especially beneficial in rheumatoid arthritis.
- Mental Health: Fish oils contain DHA, one of the structural fatty acids of the brain. Fish oils are therefore associated with brain development and improved mental performance. See DHA section for more detail.
- Eye Health: DHA, an omega 3 fatty acid derived from fish oils, is required for development of the retina. See DHA section for more detail.

Do not use with warfarin or anti-coagulant medications.
It is advisable to take extra Vitamin E when taking fish ois to help protect them and prevent oxidation in the body.
