NOW Cod Liver Oil Extra Strength delivers 1,000 mg of cod liver oil per softgel, providing a rich source of omega-3 fatty acids EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), along with vitamins A and D‑3. Traditionally used to support overall health and well-being, this cod liver oil is manufactured under strict quality control standards and tested to ensure it is free of potentially harmful contaminants such as PCBs, dioxins, mercury, and other heavy metals. Supportive but not conclusive research shows that consumption of EPA and DHA omega-3 fatty acids may reduce the risk of coronary heart disease. This extra strength formulation provides more cod liver oil per softgel than the standard 650 mg version, making it a potent option for cardiovascular and general wellness support. The product is non-GMO, and produced under GMP quality assurance.
