EPA and DHA are equally important in biological sense. They work together and have been committed to human health. In fact, many studies have confirmed that EPA not only has its own health benefits, but also can enhance the absorption and efficacy of DHA. The combination of EPA and DHA is more effective than using one of them alone. There is sufficient evidence to prove that EPA has a good effect on different life cycles and special diseases of human body. It is worth pointing out that most research on omega-3 is based on omega-3 (EPA+DHA) extracted from fish or fish oil products, not from seaweed (only DHA). Recently, many studies have focused on the role of EPA in alleviating inflammatory diseases of cardiovascular system and central nervous system. EPA+DHA can comprehensively improve children's immunity. In the past 35 years, more than 8,000 research papers have continuously discussed the special health benefits of Omega3-3 ingesting EPA+DHA at different stages of human life (such as prenatal and postnatal). Children need Omega3 to promote brain and vision development. This study suggests that pregnant women and lactating women should consume enough omega-3-3 during pregnancy and fetal health.

Second, the importance of lecithin

First of all, lecithin accounts for 70-80% of the dry weight of brain cell membranes. Brain cell membrane is mainly responsible for inputting nutrition for brain cells, exporting waste and protecting cells from harmful substances. If lecithin is lacking, it will damage the cell membrane of brain nerve, resulting in slow metabolism of brain nerve cells and decreased immunity and regeneration ability. Of course, the brain's thinking can't operate flexibly only by independent brain nerve cells. Only by establishing the channel of information transmission between nerve cells can the brain really have the thinking ability. And this information transmission channel is like a highway, and the pavement condition of the highway determines the speed of information transmission; The guardrail of expressway can ensure the accuracy of information transmission and prevent information from "going the wrong way"

Both DHA and lecithin can help the construction of cities (brain cells). DHA can promote the extension of inter-city expressway, while lecithin is the guardrail of expressway, which ensures cars (neurotransmitters) to travel to their destinations at high speed. Their effects on the brain are complementary and inseparable.

3. What is myristic acid?

Myristic acid is a common fatty acid, which can be found in animal fat and vegetable oil. It is also tetradecanoic acid. So named because myristic acid has a chain of 14 carbon atoms, and one end is connected with CH3 group, and the other end is connected with COOH group. Studies have shown that myristic acid has a great influence on the synthesis of cholesterol in the liver. This means that excessive intake of this fatty acid will lead to an increase in blood cholesterol levels in humans and animals.

4.what is lauric acid?

Lauric acid, also known as dodecanoic acid, is a saturated fatty acid. Its molecular formula is C 12H24O2. Although it is called lauric acid, it only accounts for 1-3% of laurel oil content. At present, the vegetable oils with high lauric acid content are coconut oil (45-52%), palm kernel oil (44-52%) and Brazil palm kernel oil (43-44%).

Myristic acid and lauric acid have strong effects on raising blood cholesterol and destroying intima of blood vessels in humans and animals.

To sum up, fish oil and seaweed oil are good and bad.
