Displaying 9 results of Menaquinone Stable Isotopes Menaquinone stable isotopes are isotopes of the vitamin K2 compound, menaquinone, that have a stable nucleus. These isotopes are used in scientific research to study the metabolism, absorption, and distribution of vitamin K2 in the body. Menaquinone stable isotopes are also used in the production of isotope-labeled compounds for use in drug development and clinical trials. These isotopes are essential tools for researchers seeking to better understand the role of vitamin K2 in human health and disease.
