The reason I purchased the Carlson Labs Cod Liver oil is I had learned that not all fish oils are equal , that some had been contaminated with mercury, and other contaminates....Carlson Labs get their fish supplies in some of the purest waters known and their testing labs use the highest of standards....I notice a difference in the feeling of my legs while using Cod liver oil.....it is a wonderful product and deserves a higher rating than 5 stars!
