About Vitamin Standards

Sussex Research Laboratories Inc. has specialized in the synthesis of high purity, high deuterium enrichment stable isotope-labelled vitamins and related compounds since acquiring Chemaphor Chemical Services in 2017. These synthetic stable isotope-labelled vitamin D2, D3, E and cholesterol products, along with their hydroxy metabolites, are of the highest quality and used by researchers worldwide. These stable isotope-labelled standards are optimal for use as gold standard analytical standards and as such are trusted in the analytical protocols of global nutrition companies and bioanalytical contract research organizations on five continents.

Our stable isotope vitamin reference standards are accompanied with a complete Certificate of Analysis (COA) and supported by comprehensive analytical data including HPLC, Mass Spectrometry and Proton NMR.
