Product Overview


  • Promotes Brain Function
  • Cogni-PS Phosphatidylserine
  • Dietary Supplement

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.

Increasing my Memory

Posted by 5177347225968910662 on Jun 26, 2017 | Verified Purchase

I've only taken 1/2 bottle so far and it definitely has increased my memory. I was beginning to forget words and names in the middle of a sentence and I remembered that my drivers license is coming due this year (and I'm 90 now). I remembered that a friend of mine was beginning Dementia and the Dr. has to notify DMV. My daughter said get some PS100. So I did, and the capsule size was perfect for me. They are working. As I was writing this, I thought, wait a minute" and went and looked at my drivers license and it is not up for renewal until Dec. 2018 so Hallelujah, by that time, I'll be smart as a whip. My daughter says "Mom you're such a good driver", so I will keep taking these and go back to playing Jeopardy. that helps too.

Thanks for your feedback!

My number 1 so far

Ooooh!)) This completely eliminated almost all my ADHD symptoms in ten days (many supplements couldn't). I started to see better in about only an hour after the first taking. But it was not sharpness, it was like a better refresh rate. One bottle has doses for 4 months and you can skip days (as I read, the half-life of Phosphatidylserine in a body is about 22 hours) so this supplement is pretty cheap. I'll take another one:-)
