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.

Heart racing

Posted by JDSEED on Apr 30, 2016

Jarrow is a great brand, and this product is liked by many. However it seemed to cause my heart to race, perhaps that's due to lowering cortisol levels. I've seen a few random reviews on the net from others who have the same experience. I used to have low cortisol, supposed to have ok cortisol levels now and weaned off cortisol prescription medicine. Perhaps that's why it didn't suit me. I still use other Jarrow products.
