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.

iHerb Customer Reviews

Dear Team, I ordered this product and paid Rs. 653 towards shipping charges. Now that this product is being delivered by DHL in Mumbai (India), they have levied further charge of Rs. 1215.98 (including Rs. 500+ taxes towards handling charges)!!! Why am I double charged??? FYI, last month I ordered the sameproduct overAmazon, but they did not charge me twice. Request a proper explanation to this, as I am feeling cheated. Though I have made the payment on DHL website, under distress so as to get the product delivered. Request you to kindly sort this issue and refund my excess money paid to DHL of Rs. 1215.98. Thanks, Anup Agarwal

Thanks for your feedback!

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!

❤️❤️❤️Excellent & Effective!

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. 🎇🎇😵

Thanks for your feedback!

Most certainly works
