Studies have shown the ability of supplemental phosphatidylserine to support healthy cognitive function. It may enhance healthy memory and thinking ability by facilitating communication between neurons. Best Phosphatidylserine contains phosphatidylserine and other essential nutritional cofactors in a formula that is suitable for vegetarians.

Big fat capsules overbloated with filler.

Posted by Reviewer1485718 on Oct 29, 2011

Phosphatidyl Serine is a great supplement for memory enhancement, but this product has an unnecessary amount of filler in it and the capsule is larger than it needs to be. Jarrow PS100 (120 caps) has the same amount of nutrient in it, with a smaller capsule. Both are equally effective. Staatsburg, New York

Excellent product

Posted by 5594108344231563819 on Jan 17, 2014

Fast shipping, works excellent for improving memory. It lower cortisol levels which is usually good, not for me as I have already lower and high doses causes insomnia and drowsiness, still at low doses it works as it should

Boosted my memory

Posted by Reviewer1172432 on Nov 06, 2012

Both me and my husband feel that this product does boost memory. Now I can recall things a lot better and don't have to wonder "Did I do this / where do I put my stuff." I've also tried the Country Life brand, which I think has a even greater effect on me than Doctor's Best, but it's siginficantly more expensive. Also neither brands help me in fighting brain fog, lose weight or sleep better. I sleep better only after I started taking a 40-minute walk at least 3 times a week since a few weeks ago, so I guess taking supplements is only part of a healthy lifestyle. This brand does contains soy.

Contains Soy

Posted by WrensNest on Mar 16, 2013

It has come to my attention that this product is made from soy. I am changing to the Now version. It cost almost twice as much, but soy is just poison for the body (see Dr. Mercola). Somehow forgot to check this product.
