Negative Positive
Title: Works for me
Review: I've used Phosphatidyl Choline daily for almost 20 years after reading about it in a men's magazine. I noticed a distinct difference in my ability to concentrate and study when I was attending evening classes back then so I've used it ever since. This Source Naturals product is reasonably priced and is of equal quality to any other similar product I've used so I'm happy with my purchase..
