Fish oil (in particular, cod) is fish, extracted manually—for instance, from a large cod liver. Nature’s oil is found in large quantities in marine fish of the cold waters of the world’s oceans – in mackerel, herring, and other fatty fish. In cod liver oil, as in other fish oils, numerous polyunsaturated fatty acids are stored.

This substance consists of fatty acids with their admixture. Various vitamins and mineral complexes are included in the impurities. The key value of this natural oil is the essential of omega-6 and omega 3 fatty acids. They are irreplaceable because the human body has not got the ability to synthesize them itself, so people must constantly get acid from food. As for vitamins and minerals, although they are useful, these substances can be obtained from other foods.
If omega-6 is present in some vegetable oils, DHA omega 3 is found only in fish. Therefore, it is impossible to replace fat even with useful olive oil. As far as omega-3 is concerned, this acid can also be found in some types of algae, but it is not difficult to understand that a person is simply unable to eat as many algae as necessary to the proper body function.
Among omega 3 benefits is accelerating the restorative processes of the body, repairing muscles, cutting down the level of stress hormone cortisone, improving the condition of the skin and leading to normal blood pressure. Omega 3 supplements are safe and could be purchased worldwide.
