"Menadione is metabolized by the human body into K2" WikiPedia
In the United States, menadione supplements are banned by the U.S. Food and Drug Administration because of their potential toxicity in human use. Low-dose menadione is still used as an inexpensive micronutrient for livestock in many countries. Forms of menadione are also included in some pet foods in developed countries as a source of vitamin K. These doses have yielded no reported cases of toxicity from menadione in livestock or pets.
