Cod liver oil has been taken for generations, and Nordic Naturals have built a business on doing it properly rather than cheaply. The oil comes exclusively from wild Arctic cod livers, with no fish body oils and no synthetic additives blended in. That matters because Arctic cod carries the highest natural DHA content of any cod species, so the profile is genuinely different from a generic cod liver oil. Three softgels deliver 750mg of total omega-3s, with 360mg DHA and 240mg EPA, comfortably above the 500mg daily EPA and DHA figure most expert bodies recommend. The form is the technical point. These omega-3s are in triglyceride form, the way they occur naturally in fish, rather than the ethyl esters most concentrated fish oils use. Triglyceride form costs more to produce and absorbs more readily. Nordic Naturals describe their supply chain as vertically integrated from boat to bottle, and every batch is third party tested for heavy metals, dioxins and PCBs, with certificates of analysis available on request. Freshness is tested as well as purity, which is the part most brands skip and the reason cheap fish oil tastes the way it does. The natural lemon flavour handles the rest. Vitamins A and D are naturally present in the oil rather than added.
