Fish oil is the primary dietary source of Omega-3 polyunsaturated fatty acids, with EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) being the two most biologically active components. The quality of fish oil supplements varies significantly; key indicators for assessing product quality include the content, ratio, purity, and freshness of EPA and DHA.
