DHA is a major component of the growth and maintenance of cells in the nervous system, and it is also an important component of the brain and retina. The content of DHA in the human cerebral cortex is as high as 20%, accounting for the largest proportion in the retina of the eyes, accounting for about 50%. Therefore, it is very important for the intelligence and vision development of the fetus.

EPA is the abbreviation of Eicosapntemacnioc Acid, which is the main component of fish oil. E is a polyunsaturated fatty acid, which is an important nutrient that the human body cannot synthesize, so it is called essential fatty acid.

ARA, scientific name eicosatetraenoic acid, also known as arachidonic acid, is a long-chain polyunsaturated fatty acid, and it is an essential fatty acid in early childhood. The lack of ARA may be seriously harmful to the development of human tissues and organs, especially the development of brain and nervous system.

Extended data:

In 20 10, it was clearly stipulated in the national food safety standard infant formula that if docosahexaenoic acid (22:6 n-3) was added to infant formula, at least the same amount of eicosatetraenoic acid (20:4 n-6) should be added. The content of eicosapentaenoic acid (20:5 n-3) in long-chain unsaturated fatty acids should not exceed that of docosahexaenoic acid.

In other words, if DHA is added to infant formula, at least the same dose of ARA should be added. And the dose of EPA should not exceed the dose of DHA.
