                                The National Drug Code (NDC) is a unique, three-segment number assigned to every human drug product marketed in the United States, as required by the FDA. While 'vitamin K' is a broad term, the prescription form of vitamin K, phytonadione, has specific NDC numbers associated with its various manufacturers and formulations.
