Re–esterified triglycerides have been shown to be superior in absorption when compared to ethyl esters and free fatty acids.
Ethyl Esters vs. Triglycerides
The chemical structure in which the omega–3 fatty acids are delivered can play an important role in their absorption. Recent data have demonstrated that omega–3 fatty acids delivered in a triglyceride form may result in greater plasma levels and a higher omega–3 index compared with omega–3 fatty acids delivered in the form of ethyl esters.
Omega–3 Index After Supplementation with rTG or EE Omega–3 Fatty Acids
Re–esterifed triglycerides lead to a faster and higher increase in the omega–3 index (the percentage of EPA+DHA in red blood cell membranes) when compared to ethyl ester fish oil concentrate at the same dose.
