Omega 3 comes from Marine and plant sources. Some plant sources of omega 3 are flax seed, chia seed, hemp and walnuts. Plant sources of omega 3 are in the form of Alpha-linolenic acid (ALA) that does not convert well to the 2 most important omega 3 fatty acids EPA and DHA. Marine sources provide omega 3 directly in the form of EPA and DHA and are a much better way to get these essential omega 3 fatty acids. Some marine sources of omega 3 are squid, mussels, fish and krill. The majority of omega 3 studies have used omega three from fish oils. The best fish to source omega 3 from are cold water fish like Sardines, Anchovies, Salmon , Herring and Mackerel. Omega 3 fish oil supplements have become very popular over the last 20 years due to the positive health benefits of consuming more omega 3. Most nutrition experts will recommend consumption of fish 2-3 times per week and not more due to the potential toxicities that can be in farm raised fish and wild caught fish. Wild Alaskan Salmon and Sardines seem to be two of the safest fish with some of the highest levels of omega 3. A high quality concentrated triglyceride form (rTG) omega three fish oil seems to be the best way to get these valuable essential fatty acids.
