Vitamin Stable Isotopes

sadhffkj 'Stable isotope labelled vitamins are used extensively by research and diagnostic laboratories and are now key compounds as laboratory testing transistions from traditional to advanced techniques such as LC-MS/MS. Vitamin D and related metabolites are of key interest for a variety of diseases ranging from bone health, intestinal absorption, immune diseases and cancer. Vitamin D can be obtained either through dermal synthesis from sunlight or diet. In the liver it is hydroxylated at the 25 position. Then hydroxylation in the kidney at the 1 position produces 1,25-Dihydroxyvitamin D, the most biologically active form.'
