Properties

Compounds possessing vitamin K activity are all derivatives of naphthoquinones; the two naturally occurring forms are phylloquinone (vitamin K1, synthesized by green leafy plants) and menaquinones (vitamin K2, synthesized by microorganisms) (Illus. 1).

Apart from natural sources, the most common source of vitamin K used in animal feeds is the synthetic derivative menadione, or vitamin K3, either as menadione sodium bisulfite (MSB) or its complex (MSBC). Other stable sources of vitamin K that are commercially available are menadione dimethyl pyramidinol bisulfite (MPB) and menadione nicotinamide bisulfite (MNB).
