Purity That Sets the Industry Standard

For the purity and consistency you want in your nutritional products, trust Ajinomoto amino acids. Our pharmaceutical-grade amino acids are between 99% and 100% pure; other manufactured amino acids have more than six times the impurities.

Ajinomoto amino acids are used for multiple nutritional applications, including intravenous solutions, infant and pediatric formulas and other dietary supplements. We're also the creators of Ajipure and Tryptopure, the purest form of tryptophan and the only version to have an FDA-approved Drug Master File.

As your needs and FDA demands increase, you want to build your products on the best foundation. Ajinomoto is a research leader in the nutritional physiology of amino acids, generating knowledge and understanding of the properties and behavior of amino acids, and creating even more medical and nutritional applications.
