Vitamin K: Phytonadione is the chemical name for "vitamin K". Vit K contains two natural vitamers: Vit K1 and Vit K2. To make things more complicated, Vit K2 in turn, consists of a number of related subtypes. Names for Vit K1 are: phylloquinone, phytomenadione or phytonadione. Vit K2 homologues are called menaquinones. Synthetic types of Vit K also exist (K3, K4, K5)
