Phosphatidylserine is an organic compound that occurs naturally in the cell membranes of living organisms. It plays an important role especially in cells of the central nervous system. It positively influences the functions of the cellular membrane of neurons, such as the release of neurotransmitters, signal transduction or intercellular communication. Phosphatidylserine is therefore a substance necessary for basic brain functions, activates and regenerates nerve cells. It increases the secretion of neurotransmitters such as: dopamine, acetylcholine and noradrenaline, and also increases the level of glucose in the brain. This has a beneficial effect on the central nervous system, such as perception, memory or association. It can also have a positive effect on coping with stress.
