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. In warm weather, the sunshine produces high and usually sufficient levels of vitamin D without any supplementation necessary;
I do not recommend consuming cod liver oil in the warm weather months or climates, as this can result in an excess of vitamin D in your system and consequential complications. Conversely, in cool weather, your body needs more vitamin D, and so I recommend cod liver oil versus fish oil in cool weather months or climates.
general rule: Take cod liver oil from autumn to early spring, and fish oil from late spring through the end of summer. You will need to adjust your fish oil intake depending on where you live in relation to the equator. Those who live in the direct vicinity of the equator will most likely not need to take cod liver oil, as your
vitamin D intake from the sun will be sufficient.
Always take vit. e with oil supplement
Fish oils are beneficial in the prevention of cancer and cardiovascular disease. They do, however, oxidize very easily and therefore add to the oxidant stress on the body.
The vitamin E concentration in the red blood cells dropped very significantly when fish oil was ingested but more than recovered with the vitamin E supplement. It is concluded that the negative effects of fish oil consumption can be overcome by taking them together with vitamin E.
