Phosphatidylserine occurs as a normal component of cell membranes. It is the major phospholipid in the brain. Phosphatidylserine enhances cell membrane fluidity, which improves cellular metabolism. This will improve neuronal communication and strengthen memory and learning. One overall effect is that the individual will feel a sense of well-being and peacefulness.

Oral supplementation of phosphatidylserine has been shown to increase memory and learning and has positive effects on the neurotransmitters norepinephrine and serotonin, and dopamine-depressed patients. Phosphatidylserine has been shown to help establish normal down-regulation of cortisol secretion in chronically stressed individuals. In this regard, it functions similarly to l-deprenyl (a pharmaceutical) and may have some use in hyperadrenocorticism, as well as in geriatric senility.

Phosphatidylserine (PS) is essential for nerve cell membranes to maintain the environment required for optimal brain function.

Abundant clinical research has shown this nutrient to be important in helping to optimize cognitive function, particularly in the aging brain.

Phosphatidylserine improves cell-to-cell communication in the brain, and thus cognitive function, at least in part by increasing cell membrane fluidity.

Other mechanisms of action include improved cell metabolism (such as glucose utilization) and enhanced neurotransmitter formation.

Phosphatidylserine also appears to have antioxidant activity, potentially protecting the brain from free radicals.
