Omega 3/EPA/DHA is a 100% Food supplement that is intended to supply nutrients needed to provide high quality herring source essential fatty acids like omega 3 as well as EPA, DHA, and support factors.  In addition to their structural roles, essential fatty acids modulate cell to cell interactions.  Western diets are notoriously low in life-sustaining omega-3 essential fatty acids.  This product is molecularly distilled for purity and to insure it meets quality standards. Omega 3/ EPA/ DHA naturally contains those nutrients found in molecularly distilled Herring oil. Food nutrients are better because they contain important enzymes, peptides, and phytonutrients CRITICAL to the UTLIZATION of vitamins, and minerals which are not present in isolated USP nutrients. Published research has specifically concluded that food vitamins are SUPERIOR to synthetic/USP vitamins.
