What are the specific differences between fish oil and cod liver oil?

Fish oil and cod liver oil are both nutritional supplements that people often take with nourishing effects. Although there is only one letter difference between the two names, there are certain differences between them.

fish oil

Fish oil is extracted from fatty fat, while cod liver oil is a preparation extracted from fish livers and has a fishy smell. Both have a fishy smell and are oily liquids, but they are not the same.

Fish oil is a general term for all the oil extracted from fish, including body oil, liver oil and brain oil. Its main components are triglycerides, glyceryl phosphoethers, lipids, fat-soluble vitamins and protein degradation products. Its composition is completely different from that of cod liver oil. It contains polyunsaturated fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). It is mainly suitable for people with three highs, arthritis, gout, asthma, etc. It is forbidden to use it in children, pregnant women and breastfeeding women.

Fish oil is a good product for human health care. It can prevent arthritis, Alzheimer's disease, lower blood lipids, etc. It can lower cholesterol and triglycerides in human blood, prevent the formation of atherosclerotic plaques in blood vessels, and hinder platelet aggregation by affecting the metabolism of other substances in the body, preventing thrombosis and disease. DHA can pass through the blood-brain barrier and plays an important role in nerve conduction. It is an indispensable substance for maintaining brain function and is known as "brain gold".

Cod liver oil

Cod liver oil is a fatty oil extracted from the liver of marine fish. Its main components are vitamins A and D. The most effective way to prevent rickets in infants and young children is to supplement with vitamin AD. Among them, vitamin A can help maintain normal vision, protect the integrity of epithelial cells, help the growth and development of body tissues, protect the respiratory mucosa of children, and enhance the body's immune function; vitamin D can promote the absorption of calcium and phosphorus in food by the small intestinal mucosa, promote the reabsorption of calcium and phosphorus by the renal tubules, and promote the transfer and deposition of calcium in the blood to the bones, so as to facilitate bone growth.

Among the cod liver oils currently sold on the market, cod liver oil is the most eye-catching. It is called "liquid gold" and is the best among cod liver oils. It is currently recognized in Europe as the most suitable cod liver oil for infants and young children. For example, cod liver oil from the deep sea of ​​Norway is not only rich in vitamin A and vitamin D contained in ordinary cod liver oil, but also rich in omega-3 polyunsaturated fatty acids (including high-purity natural DHA), which helps the baby's intellectual development and win at the starting line.
