 86% of the oil from "C. finmarchicus" comes as wax esters.Studies on mice have shown that, despite consuming diets containing similar amounts of EPA and DHA, blood levels of both EPA and DHA were significantly higher in mice fed a diet supplemented with oil from "C. finmarchicus" compared to those fed an EPA+DHA ethyl ester enriched diet.Furthermore, oil from "C. finmarchicus" has been observed to have beneficial effects on obesity-related abnormalities in rodent models of diet-induced obesity at EPA and DHA fatty acid concentrations considerably lower than the concentrations used in similar earlier studies using other sources of EPA and DHA.
