Cod Liver Oil

Cod liver oil is a dietary supplement derived from the liver of cod fish. As with most fish oils, it contains omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) and also vitamin A and vitamin D.

Any main meal, like breakfast, lunch or dinner is a good time to take cod liver oil. Research shows that there are many benefits to taking cod liver oil supplements, including heart health support, immune support, and bone health.
