Cod liver is a source of omega 3 fatty acids in the form of EPA and DHA. However, typical cod liver oil composition is only EPA 12%, DHA 9%, quantities which are less concentrated than in oil taken from the whole fish.
Although Cod liver oil is a significant source of the fat soluble vitamins A and D, achieving therapeutic doses of EPA and DHA may result in undesirably high levels of vitamin A and D intake. A fish oil concentrate may therefore be a better choice.
What it does
- Growth and Development: Cod liver oil contains vitamin A, a fat soluble nutrient that influences growth and development. Deficiencies of vitamin A are especially apparent in the lining of the cornea of the eyes, respiratory tract, intestinal tract, skin, urinary tract and the ducts of secretory glands.
- Skin Health: Vitamin A supplementation from cod liver oil has been shown in research to benefit various skin disorders such as acne, dermatitis and psoriasis.
- Eye Health:
Vitamin A is needed by the rods and cones in the eye’s retina, responsible for night and daytime vision respectively.
- Bone Health:
Cod liver oil contains vitamin D, an important nutrient that facilitates the absorption of calcium from the gut.
- Cardiovascular Health: EPA from fish oils have an antithrombotic effect, lipid (triglyceride) lowering, reduced blood and plasma viscosity, and improvements in endothelial dysfunction. Omega 3 fatty acids have been shown to inhibit the activity of a chemical called thromboxane which causes platelets to stick together.
Fish oils appear to reduce triglycerides in addition to improving the ratio of HDL and LDL cholesterol.
- Hypertension: Omega 3 fatty acids are increased, especially when taken in the form of fish oils have a blood pressure lowering effect.
- Inflammatory Conditions:
Omega 3 fatty acids suppress the production of inflammatory compounds produced by white blood cells.
