Cod Liver Oil Overview

Cod Liver Oil Cod liver oil is derived from the liver of the Atlantic cod fish. It is a rich source of omega-3 fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), as well as vitamins A and D. Cod liver oil is used as a dietary supplement to provide the health benefits of omega-3 fatty acids and vitamins A and D. Omega-3 fatty acids are important for maintaining heart health and can help to reduce inflammation, lower blood pressure and triglyceride levels, and may decrease the risk of heart disease. While Cod liver oil and fish oil are both sources of EPA and DHA, there are some key differences between the two. For example, cod liver oil is derived from the liver of the Atlantic cod fish, while fish oil is typically derived from the body tissue of oily fish such as salmon, sardines, and anchovies. Additionally, cod liver oil generally has a stronger fishy taste and smell than fish oil due to its liver source.
