Soy Lecithin-Derived Phosphatidylserine Plus Phosphatidic Acid: Effects on Brain Functions in Elderly Patients with Alzheimer's Disease and Dementia

Phosphatidic acid (PA) and phosphatidylserine (PS) and are natural constituents of healthy brain cell membranes, which have been recognized since the 1970s as essential to normal neuronal functioning. PA is a precursor in the formation of other phospholipids, including PS and phosphatidylethanolamine (PE). Also, it has an impact on membrane rigidity/flexibility, which is important in modulating exo-and endocytosis. PS is also an important precursor for PE synthesis. Since PS predominantly occurs in brain cells, but normal diets do not include the consumption of brains, PS is available to our brains mostly via natural "production" in our bodies.
