L-α-phosphatidylserine (Brain, Porcine) (sodium salt) is widely used in the field of cognitive health and neuroscience. It is commonly incorporated into dietary supplements aimed at improving memory, focus, and overall brain function, particularly in aging populations. Research suggests it may help mitigate cognitive decline and support mental clarity. Additionally, it is utilized in studies exploring cellular membrane dynamics and signaling pathways, as it plays a key role in maintaining cell structure and function. In the pharmaceutical industry, it is investigated for its potential in treating neurodegenerative disorders such as Alzheimer’s disease. Its applications also extend to cosmetics, where it is included in formulations designed to enhance skin barrier function and hydration.
