Amino acids are often referred to as the building blocks of life. As a core constituent of proteins, amino acids play a vital role in a range of biochemical processes that govern our metabolism and health.
When these amino acids are manufactured and purified to the highest quality standards, they become an essential ingredient in countless products used across areas including medical nutrition, nutraceuticals, APIs, excipients, cell culture and many more applications.
For more than 60 years, Evonik has been one of the world’s leading and most trusted suppliers of pharmaceutical amino acids. In the production of our REXIM® amino acids, we combine large‑scale fermentation, enzymatic bioconversion, and chemical synthesis with advanced purification technologies at two reliable manufacturing sites in Europe and Asia, ensuring highest‑purity, pharma‑grade consistency and offering value‑added services for amino acids, salts, and derivatives.
Our amino acids are available in different grades and being used amongst different application areas:
