Fish oil and cod liver oil are only one letter apart, but they are completely different. Vitamin AD drops, which are often called "cod liver oil", are not exactly the same as cod liver oil. The following article makes a simple distinction between fish oil, cod liver oil, and vitamin AD from the three aspects of ingredients, indications, and suitable populations. Let's learn about the differences in ingredients

1. The main component of fish oil is ω-3 unsaturated fatty acids

Fish oil is a general term for all oily substances in deep-sea fish, including body oil, liver oil, and brain oil, etc. It is an oily liquid with a faint fishy smell.

The main components are ω-3 unsaturated fatty acids including EPA and DHA.

DHA is an important component of the brain and retina, and is an indispensable material basis for the formation, development,dha algal oil powder and operation of brain cells.

EPA is an important "cleaner" of blood vessels, which dredges and cleans blood vessels, improves blood viscosity, regulates blood lipids, and promotes fat metabolism.

2. The main components of cod liver oil are natural vitamins A and D

Cod liver oil is extracted from the liver of marine fish, and its main components are natural vitamins A and D. In addition, gelatin, purified water and glycerin are added.

3. Vitamin AD drops only contain synthetic vitamins A and D

Vitamin AD drops are mostly artificially synthesized, usually vitamin A and D in a ratio of 3:1. The ingredients are only vitamin AD, so to be precise, vitamin AD cannot be called "cod liver oil", but "artificially synthesized vitamin AD oil".

Differences in indications

1. Fish oil promotes brain and vision development

The efficacy of fish oil mainly comes from its rich polyunsaturated fatty acids. For example, the familiar DHA is an important component of the cerebral cortex and retina, which is essential for brain development and vision development. More importantly, fish oil contains a lot of EPA, which can lower blood lipids and reduce blood viscosity.

2. Cod liver oil is used to prevent and treat vitamin AD deficiency

The main components of cod liver oil are fat-soluble vitamins A and D. It is often used to prevent and treat night blindness, corneal softening, etc., and it also has a protective effect on epidermal tissues such as the upper mucosa of the respiratory tract.

3. Vitamin AD drops have the same efficacy as cod liver oil

It is used to prevent and treat vitamin A and D deficiency. Such as rickets, night blindness and tetany in children.

Note: Vitamin A and D are essential substances for human growth and development, especially for the development of fetuses and infants, the integrity of epithelial tissues, vision, reproductive organs, the stability of blood calcium and phosphorus, and the growth and development of bones and teeth.
