Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

Rated 4 out of 5 by 4 reviewers.
Rated 5 out of 5 by Madelaine I am very happy to have found Swanson's AjiPure form of phenyalanine for just a little more cost than regular l-phenylalanine. I like knowing that I am taking pharmaceutical grade, the purest form. AjiPure is a trademark of Ajimoto, the Japanese chemical manufacturer that is respected for it's pure, ultra high quality, pharmaceutical grade amino acids. When I run out of some other supplements, I will replace them with Swanson's AjiPure products. October 17, 2013
Rated 1 out of 5 by SKIP IT I love using Pure, Crystalline, Pharmaceutical-Grade Free-Form Amino Acids, and have done so for many decades. However, I have never liked taking L-Phenylalanine. It did just the opposite of what I wanted in the way of putting my mind at ease when I first tried it back in the 70s. After seeing some material on L-Phenylalanine recently, I thought about trying it again to see if things had changed. They hadn't. I cannot recommend it to anyone. In fact, my recommendation would be to just skip it. July 7, 2013
Rated 5 out of 5 AjiPure L-Phenylalanine This pharmaceutical grade amino acid is a part of my supplement regimen that I, as a news reporter use to keep my short- and long-term memory sharp. I've shopped around for supplements, and found that Swanson's offers the highest quality at reasonable cost. March 11, 2013
