Phosphatidyl Serine by Doctor's Best delivers the essential brain nutrient phosphatidylserine in a matrix of other phospholipids and cofactors. Phosphatidylserine and other phospholipids are structural components of brain neurons that can enhance cell-to-cell communication. Studies have shown the ability of supplemental phosphatidylserine to support healthy cognitive function. It may enhance healthy memory and thinking ability by facilitating neuronal communication. Doctor's Best Phosphatidyl Serine delivers phosphatidylserine and other essential nutritional cofactors in a liquid softgel, providing added stability to these key phospholipid molecules.

Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

Best Phosphatidyl Serine is rated 3.5 out of 5 by 2.
Rated 5 out of 5 by from great I did some research on brain function and found this. I recently went back to college but I guess I've been 50's glitchy. Forgetting things.. So this helped a lot. I also tried the Swanson brand also good.

Rated 2 out of 5 by from haven't seen any changes I haven't seen any changes whatsoever, so I'm changing to a different brand in hopes that I will see a difference in memory, and everything else it was touted for. I decided to try CDP-choline, from what I read, it has a more noticeable affect and quicker, so we'll see!
