Research suggests Omega-3 fatty acids, including Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA), are linked to a healthy heart, lungs, and body, where they are used in a variety of processes. We use mercury free, molecularly distilled fish oil which is third party tested to guarantee its Pharmaceutical Grade quality. The ingredients are so pure that you could even bite into the softgel and not experience the typical "fishy taste" often found in other brands. Ours even has a hint of lemon flavor for an even better aftertaste. Check out this page on our website for more information.
