Break Down & History

As the name suggests, cod liver oil is extracted from the livers of Atlantic cod. It is usually consumed as a dietary supplement and is packed with nutrients. Cod liver is one of the best sources of omega-3 fatty acids (DHA) and (EPA). It also contains high amounts of vitamins. They include Vitamin D and vitamin A. The accurate concentration of fish oil nutrients depends on the species of cod.

Cod liver oil was first practiced in medicine in 1789. It was used to treat people with rheumatoid arthritis. It also treated people with rickets back in 1824. By around 1930, the fatty acids were frequently being administered to different people. Children were particularly given to safeguard them from vitamin D deficiency, inflammation, rickets, and other conditions.

Fish oil is derived from the tissues of deep-sea cold-water fish like trout, tuna, herring, mackerel, salmon, and cod. Fish oil is gotten from the livers of cod. It contains less omega -3 fatty acids compared to other typical fish oils. However, it contains more vitamin D and vitamin A. You can get enough of these fatty acids from the diet by consuming fish regularly. However, if you don’t consume fish, you will likely get fatty acids from regular fish oil supplementation. Additionally, if you don’t eat oily fish, you can get supplementation with fish oil.

There are two major types of vital dietary fatty acids; omega-3 and omega-6. Omega-6 is plenty in most foods that we take. Grains, seeds, nuts, dairy, and meat all contain omega-6. Omega-3 is minimal in most foods we consume, including oily fish, seeds, and nuts. However, the amount of omega-3 that we consume is not what is essential. The type of omega -3 we take is what is necessary. The three main types of omega-3 contained in foods are docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA and alpha-linolenic acid (ALA). EPA and DHA are found in marine oils. ALA is contained in seeds, i.e., flax and chia.
