Phosphotidylserine ( or PS) has been shown in human trials to improve memory, increase lucidity, increase rate of learning, and to help cope with the concerns of the day and increase sociability. PS is a phospholipid, which is the principal component of all cell membranes. PS provides five special benefits:

• It activates cell-to-cell communication
• It stabilizes the inner environment of the cell
• It helps regulate cell growth
• It improves the functioning of the special recepters found on cells
• It prepares cells for activity

PS is most concentrated in the cells of the brain, where it promotes the stability and integrity of the cellular membrane as well as the ability of cells to maintain the internal balance known as homeostasis. It also promotes the functioning of special recepters that line the membranes of cells and facilitates cell-to-cell communication. In animal studies, PS has also shown the ability to induce the production of neurotransmiters and to prevent their age related decline.

These studies help explain the human clinical studies that report PS stimulates acetylcholine output and the synthesis and release of dopamine. PS is also thought to reverse memory decline. Human trials have demonstrated memory improvement, improvements in lucidity, in outlook upon life, and in the general ability to cope with the concerns of th
