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 promotes 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.
