Hi Tom
I believe that flax seed does contain sufficient EFA's like the Omega (3, 6, 9) fatty acids including the unique linoleic and linolenic acids. Flax seed oil is in fact much better than fish oil being a botanical source while fish oil being an animal source may contain more unhealthy fats. Furthermore, now fish is being contaminated with pollutants. Oils from a botanical source would be better.
Check out the botanical oils at www.osumex.com and you will find the blend of oils from 7 seeds to be very good for the body and emotional stability.
Take care
