Phosphatidylserine is required for normal cellular structure and function. Brain tissues are especially rich in phosphatidylserine (PS), but aging causes a decline in the PS content of cells throughout the body. Research has shown that in addition to improving neural function, PS enhances energy metabolism in all cells, memory, concentration, learning and word choice. In the brain, PS helps maintain cell membrane integrity and youthful synaptic plasticity.85-94 Studies suggested chronic supplem
