Lecithin, whose biological name is phosphatidylcholine, is the substance with the highest phospholipid content in human tissues, is an important component of nerve tissues and belongs to advanced neurotrophins. Lecithin accounts for about 1% of human body weight, but it accounts for 30% of brain weight in brain. In brain cells, it accounts for 70 ~ 80% of its dry weight. Lecithin is concentrated in the brain and nervous system, blood circulation system, immune system and important organs such as heart, liver, lung and kidney.
Lecithin can protect the health of brain cell membrane, help it play its normal role, ensure the nutrient input and waste output of brain cells, and protect their healthy development. Lecithin is also an important source of information transmission medium between nerve cells. Lecithin is also the main source of myelin sheath in the brain.
