Fish oil contains EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). Both EPA and DHA are known as essential omega-3 fatty acids because the body cannot make them on its own. Fish oil provides one source of these important Omega-3 nutrients. Fish Oil Concentrate is a mixture of natural triglycerides providing a dietary source of Omega-3 polyunsaturates containing Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA). Scientific evidence reveals a diet rich in long chain omega-3 fatty acids helps support healthy joint movement, a healthy immune system, a balanced mood and sense of well being, healthy kidneys, a healthy brain, strength and stamina and helps maintain cholesterol levels that are already within the normal range.
