Big fat capsules overbloated with filler.

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

Contains Soy

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.

Rancid

Posted by Reviewer3363750 on Jun 16, 2014

I opened the capsule tried the contents. It tasted rancid! I thought I would finish then as they were expensive. The next time the taste was very rancid and bitter. In the bin. Other brands are good. NOT Doctors Best!
