Vitamin K3, universally known as Menadione, is a synthetic, fat-soluble analog of Vitamin K that does not occur naturally. Unlike Vitamin K1 and K2, Vitamin K3 is strictly prohibited by regulatory agencies like the US FDA for use in human dietary supplements due to risks of hepatotoxicity and hemolytic anemia. However, it serves as an indispensable and highly stable coenzyme additive in the global animal feed, poultry, and aquaculture industries.
