Vitamins

Vitamins are organic compounds that directly or indirectly participate in an organisms’ biochemical reactions.  These are divided into two classes, based on their solubility in fat (includes A, D, E, and K) and water (includes B and C).   CIL offers unlabeled and stable isotope-labeled vitamins as neat compounds and/or in solution at specified concentrations.  These can be used in a range of applications, such as metabolism and pathophysiology explorations as well as disease biomarker evaluation.  These standards are used to obtain accurate and precise quantification of endogenous metabolites in various matrices.

Please view the availability, pricing, and specifications of our vitamin offerings below.  A summary listing of this, and other, metabolic classes is found in our Stable Isotope-Labeled Products For Metabolic Research catalog.
