Fish oil and Cod Liver oil are both great sources of omega 3 fatty acids. Omega 3’s are essential fatty acids required by the body in order to fight against many diseases. Usually these fatty acids are not present in most people’s diet because of the under consumption of fish and over consumption of vegetable oils.
The main difference between fish oil and cod liver oil is that cod liver oil is high in vitamin D. The cod liver oil has the advantage of providing vitamin D, which is necessary for most of us in the United States in the cold months of winter, when we don't get very much sun exposure on our skin in order to make vitamin D.
Many people get confused about the difference between fish oil liquid and cod liver oil. You can consider cod liver oil as fish oil+. The 2 are the same except that cod liver oil contains natural vitamin D and A.
For people who already take a multiple vitamin that supplies Vitamin A and take supplemental Vitamin D I recommend a fish oil. And for those people that don’t take any additional supplements I generally recommend cod liver oil.
Either one of these sources of omega 3 fatty acids is one of the best things you can do for your health. The list of benefits is ever growing and truly amazing.
