Another reason I prefer fish oil over flaxseed oil is that the excess consumption of ALA in flaxseed oil tends to reduce the production of gamma linolenic acid (GLA), the building block of good eicosanoids. What's excess? Anything more than one tablespoon per day. Finally, the vast body of research data on the clinical benefits of EPA is overwhelming. Therefore, supplementation with EPA as opposed to ALA will have a far greater impact in getting you into the Zone. But before you add any omega-3 fatty acid supplements to your diet, try to get those fatty acids from food itself. The best source of EPA? Salmon. Of course, you could do what your grandmother did in her day to ensure adequate levels of EPA, and take cod liver oil. >> Thank you. That was quite helpful. I think the Eades (Protein Power) originally supported Sears' view on flax, but now they seem to have reversed themselves.
