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.Studies suggest supplementation of phosphatidylserine significantly modulates cortisol levels, resulting in a more relaxed state.

Phosphatidylserine helps the brain use its fuel efficiently. By boosting glucose metabolism and stimulating production of acetylcholine, supplemental phosphatidylserine has been shown to improve the condition of patients experiencing age-associated memory impairment or cognitive decline. Thus, replacing this brain food is essential.
