Essential Fatty Acids (EFAs), Omega-3 and Omega-6 Oils, and Fish Oil

Bottom Line Summary

“Essential Fatty Acids” (EFAs) include omega-3, omega-6 and related oils such as omega-7 and omega-9.

The nutritionally essential Omega-3’s are: DHA and EPA. See diagram for more detail. Be careful not to confuse DHA for DHEA, which is a completely separate sterol hormone.

“Fish Oils” and Omega-3 products, which are extracted from the livers of cold-water fish and critters (including salmon, anchovy, sardines and  krill) contain only a certain percentage of EPA and DHA.  A good brand will specify on the label the exact amounts of EPA and DHA on the label,  as you can see below for the ResQ 1250 product

Intolerance of several fish oils brands warrants evaluation of the GI tract.

The nutritionally essential Omega-6, Gamma Linolenic Acid (GLA), may also may be low and can compete with Omega-3 for absorption and enzyme-based processes.

Balance of healthy Omega-3 and Omega-6 is the goal.

Omega-9’s and Krill oil may provide additional benefits but best after the “core” nutients are satisfactorily covered.

Omega-3 oils are called “fish oils” because fish are the most abundant source. However, all animals, including humans, will make their own when healthy and properly fed.

Certain omega-6 oils are also essential but dominated by those coming from corn, wheat, and other commodity plants. More on the ratio of omega-6 to omega-3 below.
