What is the difference between fish oil and cod liver oil?
The main difference between cod liver oil and fish oil is that cod liver oil is high in vitamin D, sometimes called the “sunshine vitamin”.* If you are outside in warm weather, sunshine produces high and generally sufficient levels of vitamin D without supplementation. I do not recommend consuming cod liver oil in the warm weather months or warm climates, as this could cause an excess of vitamin D in your system. Conversely, when the sun’s rays are very indirect, your body needs vitamin D supplementation. So I recommend cod liver oil versus fish oil in cool weather months or cool climates. Vitamin D experts suggest that anyone living north of the 30th parallel is likely to be sun-deprived for much of the year. The 30th parallel runs roughly along the Gulf Coast, from the Florida panhandle west through Texas and across to southern California. My general rule… Take cod liver oil from autumn to early spring, and fish oil from late spring through the end of summer. Adjust your fish oil i

I used to recommend consuming cod liver oil in the warm weather months or warm climates, but no longer do, as this could cause an excess of vitamin D in your system. When the sun’s rays are very indirect, your body needs vitamin D supplementation. So I used to recommend cod liver oil versus fish oil in cool weather months or cool climates. However, I have discovered that it is far better to obtain vitamin D through a form of supplementation other than cod liver oil since cod liver oil can have deleterious effects.
