The fats in EVCLO are in their natural triglyceride (TG) form which is what you would expect from completely unrefined cod liver oil. Scientific research confirms oils in their triglyceride form exhibit greater absorption over the synthetic ethyl ester (EE) form. This also means levels of EPA and DHA will be greater in those consuming triglyceride-based fish oils than those consuming ethyl esters. Please also note that the natural triglycerides present in Rosita oils are natural triglycerides and not re-esterified triglycerides which are basically ethyl esters that are reassembled back into triglycerides. Rosita does not have to recreate the natural triglyceride form because their oils are completely unprocessed.
