The chemical composition of fish oil is beneficial not only for health, but also in cosmetology. This is one of the few additives with such a wide spectrum of action.

Types and methods of manufacture

Fish oil can be divided into three groups:

  • red (used for production purposes);
  • yellow (in purified form it is used in the field of medicine);
  • white (exists as a dietary supplement).

Fat is obtained in several ways:

  1. Factory way. Fish is caught, after which the liver is immediately removed and placed in a special boiler with a temperature of up to 50 ° C. Under the influence of high temperatures, fat begins to stand out on its own. Subsequently, the remaining mixture settles at sub-zero temperatures to obtain white fat. When repeating these manipulations after some time, the fat thickens. Thus, red and yellow varieties are mined.
  2. Amateur way. This method is used by fishermen who do not have factory equipment, who want to make an additive on their own. After the fish are caught, they are stored and boarded up in barrels, they wait several weeks. After a month and a half, a barrel is opened – fat flows out of the fish on its own.
  3. Fish oil. The method of its manufacture is different from the previous ones. This oil is not extracted from the liver of a fish, but from its muscle tissue. It is in this fat that contains the most valuable additive for human health – Omega-3.

The difference between fish oil and fish oil

Liquid fish oil

Both types of fat are used by humans as a dietary supplement and have a similar composition. However, fish and fish oil have significant differences:

  1. Preparation method. Fish oil is obtained from the muscle tissue of fish, while fish oil is extracted from the liver.
  2. Taste and smell. Fish oil has a characteristic unpleasant odor and taste, which is especially pronounced if the additive is made in the form of syrup and is consumed in its purest form. Fish has a muffled odor and is almost tasteless.
  3. Price. Fish oil is made from the liver of fatty fish, and fish oil is made from muscle tissue, which is harder to extract. In general, the method of processing fish oil is much cheaper, and therefore it costs significantly lower than fish.

When buying a nutritional supplement, be sure to pay attention to what fat it is made from. Fish muscle fat is commonly referred to as “fish” or “ichthyene” oil.

Therapeutic properties

Fish oil in capsules is more beneficial for the human body than in another form. This is due to the fact that its composition mainly includes oils and fatty acids, which are oxidized by contact with air. The hermetic shell of the capsules impedes this process, which affects the good absorption and long-term preservation of beneficial properties.

  • cod;
  • burbot;
  • sardine;
  • trout;
  • mackerel;
  • shark.
