什么是PS？

磷酯酰丝氨酸

Phosphatidylserine, PS

一种天然磷脂，构成细胞膜的重要组成成分。PS在脑神经细胞中大量存在，被称为“脑的营养素”，而人脑的神经细胞膜的干重约50%是磷脂。其功能主要是改善细胞功能，调节神经脉冲的传导，增进大脑记忆功能，有效预防和减轻大脑功能衰减。

A natural phospholipid, an important component of cell membrane. PS is abundant in brain nerve cells and is called "brain nutrient". And about 50% of the dry weight of human brain nerve cell membrane is phospholipid. Its main functions are to improve the cell function, regulate the transmission of nerve pulses, enhance the memory function of the brain, and effectively prevent and reduce the decline of brain function.
