Healthy Care Fish Oil 1000mg Omega-3 (odourless) uses fish oil extracted from cold water fish. It is a natural source of the marine Omega-3 fatty acids Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA), which are classified as essential fatty acids. They cannot be synthesised in the body and must therefore be obtained from dietary sources. The fish oil supplement is beneficial if you cannot take the recommended 2-3 serves of fish a week.
