The fats in Rosita Extra Virgin Cod Liver Oil 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 omega-3 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 our oils are completely unprocessed.
