Cod liver oil is an excellent source of omega-3 fatty acids (EPA and DHA), which support heart health and brain function. It is also uniquely high in Vitamin D for bone health and Vitamin A for immune function and vision. Additionally, its anti-inflammatory properties can help reduce joint pain and stiffness.
While both provide omega-3 fatty acids, regular fish oil is extracted from the flesh of fatty fish, whereas cod liver oil comes specifically from the liver. This difference means cod liver oil contains high levels of vitamins A and D, which are typically not present in standard fish oil supplements.
No, cod liver oil is not vegan as it is an animal-derived product extracted from the livers of Atlantic cod. For a vegan alternative that provides omega-3s, algae-based oils are the most comparable plant-based source.
It is not recommended to cook with cod liver oil because it has a very low smoke point and its delicate omega-3 fatty acids and vitamins can be destroyed by heat. Furthermore, it has a very strong fishy flavor that is generally unpleasant when used as a cooking oil.
Yes, cod liver oil is highly keto-friendly because it consists of 100% fat and contains zero carbohydrates. It is an excellent way for those on a ketogenic diet to incorporate healthy polyunsaturated fats and essential fat-soluble vitamins.

Pure cod liver oil has a distinct, strong fishy flavor and a heavy oily texture. Because many people find the natural taste unappealing, it is often sold in capsule form or as a liquid flavored with natural citrus or mint oils to mask the fishiness.
While cod liver oil is calorie-dense at 902 calories per 100g, it is consumed in very small doses, usually a teaspoon or two. The omega-3s may support metabolic health and reduce inflammation, but it should be used as a nutritional supplement rather than a primary weight-loss tool.
