Sources of Omega 3 Oil

Omega-3 fatty acids (found in Omega-3 oil) are important to those interested in cardiac health. Two common sources are vegetable oils and fish. The best source might be algae.

  1. Varieties

    • Although there are a number of Omega-3 acids, those of most interest are ALA (alpha-linolenic acid), EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid).

    Differences in Omega-3 Desirability

    • ALA is prevalent in vegetable oils such as flax, canola and soybean. It should not be equated with EPA and DHA, which predominate in fish oils. EPA and DHA are considered superior for cardiac health purposes.

    Vegetable Oil Sources of ALA

    • Flax, canola and soybean oils are excellent sources of ALA Omega-3 fatty acid. ALA must be converted by the body to be useful. Although advertisers highlight ALA-rich vegetable oils for their Omega-3 content, it is fish oil that is considered most beneficial.

    Fish Oil Source of EPA and DHA

    • Salmon, herring, mackerel, anchovy and sardine oils are rich in EPA and DHA. Although fish don't produce these chemicals, algae they eat do. The fish might be contaminated with mercury, PCBs and dioxin, but there are differences of opinion as to whether this concern should exist for the purified oil.

    The Market Response to Concerns

    • In view of such concerns, algae-based Omega-3 has been introduced on the market.

    Use Precaution

    • In matters related to health, it is wise to consult your physician first.
