Good fats, or Omega-3 fatty acids as they are known, are essential fatty acids. They are called essential as the body is not able to make them on its own. Double Strength Omega consists of the most important types of Omega-3 EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid). These are commonly found in oily fish such as sardines, mackerel and salmon. Both EPA and DHA contribute to the normal function of the heart. This product has an ideal balance of Omega-3 actives and is molecularly distilled to remove mercury, giving you optimal support for daily wellbeing.
