Is fish oil the same as cod liver oil?

Generally speaking, fish oil is not cod liver oil, and it is recommended to distinguish between the two and not confuse them. Fish oil is typically extracted from fish and its main component is unsaturated fatty acids. It is also rich in various nutrients such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). In medicine, it has the effects of preventing and treating cardiovascular diseases and enhancing memory. Cod liver oil, on the other hand, is generally extracted from the livers of sharks and cod. Its main components are vitamins A and D. In medicine, it can treat vitamin AD deficiency and can also improve conditions such as rickets, night blindness, and tetany in children. The definitions of fish oil and cod liver oil are different, and it is recommended to distinguish between them.

During the consumption of fish oil or cod liver oil, attention should be paid to the dosage. If symptoms such as skin itchiness or skin rashes occur, it is necessary to stop using the medication immediately and seek medical attention. If there is an allergic tendency to any of the ingredients, avoid using them to prevent discomfort. Additionally, it is important to maintain a good lifestyle, avoid exerting too much pressure on oneself, and ensure proper rest without overexertion, in order to avoid weakening one's own resistance.
