Many Americans take cod liver oil as a dietary supplement because of its health properties. The oil, as its name implies, is made from the liver of the cod. It is sold in both liquid-oil form and in capsules. Unlike fish you buy at the market, which may contain mercury, cod liver oil from quality sources go through a purification process and contain no traces of these harmful contaminants.

Cod liver oil is a rich source of many helpful vitamins and nutrients, including vitamin A, vitamin D, and two Omega-3 fatty acids: DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid). Research suggests that taking cod liver oil lowers your risk of depression, builds strong bones and teeth, reduces inflammation in your body and keeps the cardiovascular and nervous systems healthy.

Taking cod liver oil can help reduce the pain from arthritis, bone and muscle aches, and other inflammation conditions. Experts believe that this oil can also help ease PMS and menopausal symptoms. Because of the vitamin D levels, it can improve bone mineral density in women with osteoporosis.
Disease Prevention
Because of the Omega-3 fatty acids (DHA and EPA) that are in cod liver oil, this supplement helps to prevent heart disease. It also improves memory and brain function, and contributes to better bone health. Studies suggest that cod liver oil may lower the risk of type 1 diabetes in children as well as lowering the levels of bad cholesterol in your body. The nutrients in cod liver oil can also aid in the prevention of cancer, including lung cancer and childhood leukemia.
