Product Description

Phosphatidylserine powder (PS) is from the phospholipids family, which is the only one that could control the functioning of key membrane proteins. Usually, it refers to a series of compounds of PS, in that the lipid-acetyl residues differ greatly in a variety of product sources. Phosphatidylserine exists in all biomembranes of animals, higher plants and microbes as an important component of cellular phospholipids, for example, it makes 10-20% of total phospholipids in brains of mammals, and plays essential roles in many cellular metabolic processes.

This kind of Phosphatidylserine Powder is extracted from the residue of natural soybean oil and is an active substance of cell membranes, especially in brain cells. It is mainly used toimprove the function of nerve cells, regulate the conduction of nerve impulses, and improve the memory function of the brain. Because of its strong lipophilicity, it can quickly enter the brain through the blood-brain barrier after absorption, so as to relieve vascular smooth muscle cells and increase blood supplyto brain.
