Stable Isotope Labeled and Unlabeled Vitamins and Vitamin Solutions

Vitamins are responsible for a variety of essential functions including calcium homeostasis, fatty acid metabolism and blood clotting. Vitamin deficiencies have historically been responsible for wide ranging health consequences, including scurvy and rickets. The past prevalence of deficiency caused diseases coupled to the likelihood that vitamins are playing unknown roles in other health-related questions has increased interest in this area of research. Many nutritional studies have been undertaken to study dietary intake and bioavailability,1 identification and concentration within complex samples2 as well as to further elucidate function.2b,2f

Isotec Stable Isotopes offers a broad collection of stable isotope labeled vitamins and vitamers, including products with nonexchangeable 13C and 15N labels. These products are provided in convenient quantities and/or solutions, ideal for use as internal standards or in other analytical applications.
