Phosphatidylserine (PS) is a type of phospholipid and is an essential component of cell membranes. Cell membranes are composed of a double layer of lipid molecules (primarily phospholipids) in which enzymes and other proteins are embedded. As PS is also a phospholipid, it is well suited to support enzymes and proteins in nerve cell membranes. By strengthening and revitalizing the membranes that surround brain cells, PS also improves nutrient flow into the cells, providing them with the food they need to function properly. This, in turn, promotes overall brain function.

PS activates and regulates proteins involved in proper nerve cell function, including the generation, transmission, reception, and storage of nerve impulses. Unlike many pharmaceutical drugs that raise or lower single chemical transmitters, PS supports multiple major transmitter systems, promoting overall brain function.

PS is naturally present in the brain and is synthesized from phospholipid building blocks. This nutrient is highly bioavailable (easily absorbed by the body) and is able to breach the blood-brain barrier to exert its positive influence on the brain. Once inside nerve cell membranes, PS also acts as a storehouse for phosphatidylcholine (PC) and phosphatidylethanolamine (PE) -- similar phospholipids also present in cell membranes.
