What is DHA?

The scientific name of DHA is docosahexaenoic acid. It is a very important unsaturated fatty acid in the human body.algal oil powder manufacturer It is the main component of the growth and maintenance of nervous system cells and an important component of brain and retinal lipids.

What are the benefits of DHA for infants and young children?

Many clinical trials have confirmed that infants and young children who supplement DHA have significant improvements in intelligence and vision tests. Infants and young children who supplement DHA can see 1.5 more lines on the vision chart at 12 months than those who do not supplement DHA. algae oil supplement Good early vision in infants and young children is more conducive to their intellectual development, and infants and young children who supplement DHA will have better performance in vocabulary, sentence making, understanding, arithmetic and other aspects when they are 4 years old. In addition, infants and young children who supplement DHA can effectively enhance their immunity and significantly reduce the incidence of respiratory infections within one year of age.

What is fish oil DHA?

In the past, we mainly obtained DHA from fish oil. The DHA in fish oil is accumulated and concentrated in the food chain,ara oil that is, big fish eat small fish, and small fish eat seaweed. DHA really comes from seaweed and is transferred to the fat and liver of fish through the food chain. . However, fish oil inevitably contains another long-chain unsaturated fatty acid - EPA, which has a negative impact on the early development of mammalian infants and young children. The WHO has expressly stipulated limiting the intake of EPA by infants and young children. In addition, ocean pollution is serious, and fish oil is obtained from the top of the biological chain, which concentrates the pollution in the ocean and inevitably contains heavy metals and other harmful substances.

What is algae oil DHA?

In the past 20 years, science and technology have developed rapidly. Now humans can directly extract DHA from algae. Algal oil DHA undergoes biological fermentation. The production environment can be strictly controlled and does not contain harmful substances such as heavy metals. At the same time, algae oil DHA contains almost no EPA, making it a good choice for people who need to supplement DHA.

What is lecithin-based DHA?

With the continuous advancement of science and technology, scientists have discovered that poultry egg yolks also contain a small amount of DHA. Unlike algae oil DHA, which has a limited absorption rate of triglyceride type DHA, the DHA in poultry egg yolks is lecithin type DHA, with an absorption rate of nearly 100 %. Natural lecithin-type DHA is mainly found in fish eggs, Antarctic krill and poultry egg yolks. However, it is worth noting that the lecithin-type DHA in Antarctic krill and fish eggs is difficult and expensive to obtain, while the amount of lecithin-type DHA in egg yolk is minimal or even negligible. Therefore, scientists innovatively added algae oil DHA to feed to feed poultry, so that concentrated and high-concentration lecithin-type DHA can accumulate in their egg yolks.

Lecithin-type DHA can directly pass through the blood-brain barrier to reach brain nerves and retinal cells, thereby promoting brain and eye development. However, in order to pass the blood-brain barrier, triglyceride-type DHA must be converted into phospholipid DHA. Therefore, the innovative production of lecithin-based DHA brings the DHA industry a big step forward and achieves a milestone victory.
