Since their discovery in the 1970s, the omega-3 Essential Fatty Acids (EFAs) have generated thousands of studies and clinical trials. Essential to life and good health, they protect against disease and can treat numerous health conditions.
The two omega-3 EFAs critical for wellness and prevention in humans are EPA (eicosapentanoic acid) and DHA (docosahexanoic acid). The third omega-3 EFA, ALA (alphalinolenic acid), found in flax, nuts, seeds and dark leafy vegetables is poorly converted (<1-2%) to EPA and DHA, and thus has questionable value for human consumption.
The best and richest sources of the omega-3 EFAs are oily fish and fish oil supplements. They supply the preferred omega-3 EPA and DHA that the body can most readily use. However, concerns have been raised over levels of mercury, PCBs, and dioxins in some fish; the content varies according to location and type of fish. In reputable fish oil supplements, the purification process removes pollutants by adding ethyl alcohol. This converts the omega-3 to a poorly absorbed ethyl ester form. However, by adding an extra step in the purification process and converting the oil back into the natural triglyceride form (same as in the fish itself), the bioavailability and absorption of the omega-3s is increased by 300%.
Most authorities now recommend 1-2 grams of EPA/DHA consumption daily for normal maintenance of good health and 3-4 grams and beyond for those suffering from chronic medical conditions.
