The primary phospholipid in brain cell membranes

  • supports healthy brain function*
  • helps modulate cortisol levels during stress*
  • to enhance memory and focus*

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.*
