Essential Fatty Acids

Fish Oil Extracts

Fish oils derive from the tissues of oily fishes like fresh salmon, herring, tuna and mackerel. These fishes don't produce the oils themselves but accumulate them from consuming microalgae that produce these oils.

Fish oil extracts are often sold in capsules because they are unpalatable in liquid form. Note, however, capsules are not suitable for young children's consumption.

Salmon Oil: This oil is high in omega-3 EFAs and also eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). EPA and DHA are important oils for brain development. Infants born to women who have high levels of this type of oil have been found to be in advantage in terms of early development and advanced attention span.

This type of oil can help thin the blood, prevent blood clotting, regulate cholesterol production and strengthen cell walls, heightening protection against viral and bacterial invasion. They are also beneficial in relieving inflammatory problems like rheumatoid arthritis, osteo-arthritis and gout.

Cod-Liver Oil: This oil is a fine source of omega-3 EFAs, vitamins A and D. However, large amounts can be toxic so take no more than prescribed on the labels. The taste of cod-liver oil may be unpalatable, but never use defatted cod-liver oil. Defatted also mean that its nutritive values have been removed.
