Product Information


Phosphatidylserine PS100
Promotes Brain Function*
Phosphatidylserine (PS) is a natural phospholipid that is an essential component of cell membranes.* Cogni-PS® promotes brain function by helping maintain neuronal membrane fluidity (cell-to-cell communication), which is associated with cognition, mental performance, attentiveness, and reaction time.* PS protects against stress-induced activity, reducing the action of cortisol (catabolic stress hormone).*
Cogni-PS® is a concentrated form of phosphatidylserine that offers superior stability.

Early on it seems helpful
GNC emailed me to review this not long after I began taking it along with Gingko Biloba. I think the test will come in 6 months to a year. But my early reaction is that I do feel more alert.

I have Bipolar Disorder and GAD and only take one medicine because I am able (through the assistance of a naturopathic doctor and integrated psychiatrist) to take supplements of natural things instead of the heavy duty drugs given to most with Bipolar Disorder. I am able to maintain a 'normal' life because of products like PS 100. PS 100 or Phosphatidylserine is something that is given to patients with memory issues and it has helped improve my short-term memory to an amazing degree. I am actually going back to college to finish my degree but will not do it without PS 100. Next to the Omegas, GABA and Theanine I take, PS 100 is one of my most important supplements. It also helps me fall asleep by quieting the noise of daily stress. I take two every morning and one about an hour before bedtime. I am no doctor but when I didn't have my PS 100 for a week ...I noticed.
