In healthy young men, taking EPA in a structured triglyceride form may result in a slightly higher level of EPA in the blood compared to a simple mixture of the same components, but the difference was not large enough to be considered statistically certain.

Effects of eight weeks of eicosapentaenoic acid and medium-chain triacylglycerol structured lipid intake on EPA/AA ratio and muscle performance in young men
This study found that a special form of fish oil (structured triglycerides) raised a key marker of EPA in the blood better than a regular mix of the same ingredients. Even though the claim said the difference was almost significant, the study actually showed it was significant — so it supports the idea that the special form works better.
