Phosphatidylserine is an important membrane phospholipid that exists in bacteria, yeast, plants and mammalian cells.
Phosphatidylserine is also known as complex neuric acid. Referred to as PS, extracted from natural soybean oil residues. It is an active substance in cell membranes, especially in brain cells. Its main function is to improve the function of nerve cells, regulate the conduction of nerve impulses, and enhance brain memory function. Due to its strong lipophilicity, it can quickly enter the brain through the blood-brain barrier after absorption, and play a role in soothing vascular smooth muscle cells and increasing blood supply to the brain.
