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.

For ASD & ADHD 8yo child

Started PS100 about 4 months ago. I do see improvements in my son. He is better regulated and more positive. He is better able to manage his anger. His teachers have feedback that he is able to focus better. He is not taking PS 100 alone. He is also taking omega and vitamin B complex.

Thanks for your feedback!

Buy it!

These are great for those of us who need a bit of a cognitive boost. They have no soy which is a must for me and I like the easy to swallow gel-tabs best. These will boost your memory and make it a bit easier to sleep at night as well. Although it can be difficult to determine whether or not the effect is a placebo effect the science seems good to me and I trust the Jarrow brand. I have tried many other formulas from them and have had good results. Recommend it. Enter *KOZ 0205* (without space) at checkout for 5% off!

Thanks for your feedback!

good product, although i had some "side effects"

Posted by iHerb Customer on Aug 13, 2017 | Verified Purchase

I bought this product for my mitochondria. I took 3 a day, but i got so tired and sometimes also nauseous with it. Probably cause toxins are being released from the cells. I recommend to take this product with binders, to bind the toxins in the gut. Good product though, does it's job, in my case i had a strong reaction, only cause i am quite ill with cfs. I do feel though, that this is a helpfull product to rebuild the cell membranes and to detox them. Best take glutathione with it.
