What is free fatty acid omega-3?

In free fatty acid (FFA) form, EPA and DHA are already separated from their glycerol backbone, so they are immediately available for intestinal absorption without requiring lipase digestion. This is the molecular state EPA and DHA exist in after digestion of regular fish oil.

How does AvailOm compare to krill oil?

Both have absorption advantages over standard fish oil: AvailOm via the free fatty acid mechanism, krill oil via the phospholipid mechanism. AvailOm provides higher EPA/DHA concentration per dose; krill oil provides co-factor choline and preferential brain uptake.

Is AvailOm suitable to take on an empty stomach?

Because FFA omega-3 does not require emulsification by bile to the same extent as triglyceride forms, AvailOm is generally well-tolerated without a high-fat meal. A small amount of food may still improve tolerance.

AvailOm vs Fish Oil: Free Fatty Acid Omega-3 Absorption

AvailOm delivers omega-3 as free fatty acids (FFA), which absorb faster and with less dependence on bile than triglyceride or ethyl ester forms.

Our Recommendation

AvailOm

Free fatty acid form absorbs rapidly without requiring digestion to release EPA/DHA, and is substantially less dependent on dietary fat co-ingestion for uptake.

Pros

+Highly studied with broad clinical evidence base
+124% relative bioavailability vs ethyl ester
+Lower cost per gram of EPA/DHA

Cons

-Requires enzymatic breakdown before fatty acids are released
-Absorption peaks more slowly than FFA form
-More dependent on dietary fat for optimal uptake

Best For

Those wanting well-researched omega-3 support with strong EPA/DHA concentration at a reasonable cost.
