Should You Use Fish Oil as Your Source for Essential Fatty Acids?

Recently there has been a debate about how to supplement our diet to get the essential fatty acids (EFAs) that we need.  This debate is centered around the notion that fish oil is a less effective source of EFAs than is what has been called “Parent Essential Oils” or PEOs for short.

Is it true that PEOs are a more beneficial source of EFAs rather than traditional sources of Omega 3 such as fish oils?

The reality is most of what you’ve heard about PEOs is simply marketing hype – yet another “latest and greatest” product touted as a more “proper” way to benefit the body.

The whole issue with essential fatty acids boils down to one thing – the quality, reliability, and safety of the processing of the supplement you’re consuming.

What’s important here is not so much where the EFAs come from – it’s how they are handled and processed.

There are very stringent guidelines that differentiate over-the-counter EFAs from the pharmaceutical grade EFAs.

Highly sophisticated handling and manufacturing processes ensure that high quality Omega 3 undergoes an advanced molecular distillation process that filters out heavy metals, pollutants, and other contaminants.

The result is a highly purified, consistent manufacturing process that exceeds the already rigorous quality standards set into place by the International Pharmacopoeia and the Council for Responsible Nutrition’s Omega 3 monograph (the industry’s voluntary standard for purity … which incidentally PEO manufacturers do NOT conform to).

Every batch of Omega 3 that goes through this process is checked for numerous contaminants – including 220 pesticides, 6 heavy metals, 7 markers of polychlorinated biphenyls (PCBs), 15 dioxins and 12 dioxin-like PCBs. Additionally, Omega 3 is screened for yeast, molds, and harmful bacteria.

The bottom line is this – don’t believe the hype.

There’s no proven benefit to getting EFAs from parent essential oils at all.

What should matter to consumers is the purity, consistency, and reliability of the EFAs they are consuming.

The issue is not one of purity” . . . what most commentators miss or don’t know is that the problem is that, as we age, the level of the enzyme (delta-6-desaturase) required to metabolize “PEOs” falls and the individual cannot make the conversion of “PEOs” to activated EFAs (EPA and GLA). D6D level at age 60 is usually about only 30% of what it was when we were at our physiological peak.
Taking ACTIVATED EFAs (EPA and GLA) bypasses this “enzyme blockage.

If I had your emaiI could send you the science lit on it. I’m on Facebook in my own name. Alternatively, get the book “The Zone Diet” by Dr. Barry Sears . . . he is the leading lipid scientist out there (formerly Boston University faculty.) One thing to know is how to balance your ratios of omega 3 to 6.
Too much 6 dries your skin and brings about constipation. Too much 3 gives you a loose bowel to the point of diarrhea.
There is merit in the idea of alternating krill oil with salmon oil for the reason that krill oil has the beneficial astaxanthin

Getting the balance of omega 3 to 6 right enables you to correctly modulate/balance your prostaglandins .. . . and that is a very important thing to do.
