Phosphatidylserine (PS) is a phospholipid that is a component of the cell membrane, particularly abundant in the brain. It is crucial for maintaining the structure and function of cell membranes, especially in nerve cells. PS plays a key role in various cellular processes, including cell signaling, cell repair, and apoptosis (programmed cell death). While the human body can synthesize phosphatidylserine, it also obtains it from dietary sources. Early commercial phosphatidylserine supplements were often derived from bovine (cow) brain cortex. However, due to concerns about prion diseases, most modern supplements are now sourced from plant substances, typically soy or sunflower lecithin (National Institutes of Health Office of Dietary Supplements). PS is recognized for its potential role in supporting cognitive function, particularly in areas related to memory and learning.
