Olympian Labs Phosphatidyl-Serine
Phosphatidylserine, one of a group of phospholipids, has long been known to have a positive effect on improving mental function. With age, the membranes around cells tend to get stiffer and more resistant to the normal movement of molecules. Less movement of molecules, including neurotransmitters across the membranes, means decreased function in brain cells. Phosphatidylserine and the other phospholipids literally "unstiffen" membranes allowing for healthy function of brain cells.
