Is Cod Liver Oil Good for You?
3.8/5 - (24 votes)
Cod liver oil that has been distilled to remove any industrial toxins and heavy metals. Still harmful, harmless, or healthy?
Harmful, due to the toxic levels of vitamin A. In fact, so much it could damage our own liver. So, not good for the cod’s liver, or ours.
