| Omega-3 fatty acids are comprised of 3 main compounds - ALA, DHA and EPA. ALA is a short chain omega-3 fatty acid, while DHA and EPA are longer chain omega-3 fatty acids. The ALA converts into DHA and EPA through a chemical pathway in the body at a rate of 4 to 10%. This means that if you eat 100 mg of the shorter chain ALA (the main omega-3 fat found in flaxseed for example) then your body will convert 4 to 10% of this into a combination of EPA and DHA producing 4 to 10 mg of these longer chain omega-3 fats combined.
While it is good to increase your consumption of omega-3 fats in general, it is the longer chain DHA and EPA that have the real physiological benefits (i.e. DHA and EPA are linked to reducing the risk of heart disease, heart attacks and mortality plus other health benefits. DHA has also been found to improve mental and visual acuity in infants). Therefore, it is better to consume the longer chain DHA and EPA than it is to consume only the shorter chain ALA, all of which are omega-3 fats with different length carbons in the molecules. The main benefit of consuming the ALA is that it converts into the DHA and EPA, although to a very limited extent.
As you can see by the following fatty acid profile, the Naturegg Omega Pro Liquid Eggs has a much higher concentration of the long chain fats (ones with 20 carbons or more) than do the Omega 3 shell eggs. Only 25% of the fatty acids provided by the shell eggs contain fatty acids with 20 carbons or more. However, over 90% of the fatty acids provided by the Naturegg Omega Pro Liquid Eggs contain 20 carbons or more. As discussed, it is these longer chain carbons that provide the true physiological benefits, making Naturegg Omega Pro Liquid Eggs similar to eating a serving of salmon or other cold water fish.
What is Omega-3?

An excerpt from this section states: Fatty Acid Supplements
"A number of investigators have reported on beneficial effects of increased omega-3 fatty acid intake in patients with coronary artery disease. Several of these studies used supplements containing long-chain - 3 fatty acids (EPA and DHA, or "fish oil") at doses ranging from 850 mg to 2.9 g/d. Other studies have shown that higher doses (3 to 4 g/d) provided as supplements can reduce plasma triglyceride levels in patients with hypertriglyceridemia. High intakes of fatty fish (1 serving per day) can result in intakes of EPA and DHA of 900 mg/d. Further studies are needed to establish optimal doses of omega-3 fatty acids (including EPA, DHA, and linolenic acid) for both primary and secondary prevention of coronary disease as well as the treatment of hypertriglyceridemia.
For secondary prevention, beneficial effects of a high dose of omega-3 fatty acids on recurrent events have been reported in the GISSI trial. A 20% reduction in overall mortality (P=0.01) and a 45% reduction in sudden death (P<0.05) after 3.5 years was reported in subjects with preexisting coronary heart disease (who were being treated with conventional drugs) given 850 mg of omega-3 fatty acid ethyl esters (as EPA and DHA) either with or without vitamin E (300 mg/d). Other studies have demonstrated beneficial effects of omega-3 acids EPA, DHA (1.9 g/d), and linolenic acid 0.8% of energy, in subjects with coronary heart disease. Consumption of 1 fatty fish meal per day (or alternatively, a fish oil supplement) could result in an omega-3 fatty acid intake (i.e., EPA and DHA) of ˜ 900 mg/d, an amount shown to beneficially affect coronary heart disease mortality rates in patients with coronary disease."
