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.

I am taking for Adrenal problems and seeing some results. It has taken time but getting there. Better then anything else I have tried.

Thanks for your feedback!

Horrible Customer Service

Posted by iHerb Customer on January 25 2018 | Verified Purchase

I ordered a bunch of supplements last month-when they didn't arrive I looked at the tracking and saw that either iHerb or Landmark had dropped my street address and apartment number when inputted (it is correct in my account), so the package was returned after having cleared customs. I contacted iHerb, and they asked me to verify my address. Great, I thought. They will re-ship them. Instead, they canceled my order without asking me first and issued a "refund" that was $21 less than what I had paid for the items in the first place. I had asked in my emails to 1) be escalated to a manager 2) find out what had happened (was this a clerical error or will this happen again to me because my account now contains an incomplete address somewhere) and 3) be assured that this would not happen again. I got none of those things. Instead I got "sorry for your inconvenience", "have a healthy day" and BLAMED for the mistake, getting a giant paragraph about how I must have given the wrong address or ordered things not allowed in my country. Meaning no one bothered to see what the problem was in the first place. Besides the fact that I had already pinpointed the error as on their end, I ordered things to Canada from the Canadian website. If things not allowed in Canada are sold on the Canadian website I would think the onus lies with iHerb, not me. So now I have no supplements, am out $21, and wondering if the CS staff are not human but robots with low reading comprehension and a limited supply of stock unhelpful phrases. Not impressed, iHerb. If any human employees are reading this, I would appreciate being treated like a fellow human. I've had better experiences with telecoms.

Thanks for your feedback!

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!
