Menadione is a synthetic naphthoquinone without the isoprenoid side chain and biological activity, but can be converted to active vitamin K2, menaquinone, after alkylation in vivo.

Vitamin K is an essential fat soluble vitamin that is important in maintaining normal coagulation, serving as a cofactor in the activation of several clotting factors and anticoagulant proteins. There is no evidence that vitamin K supplementation, in physiologic or even higher doses, causes serum enzyme elevations, liver injury or jaundice.


Menadione is a synthetic naphthoquinone without the isoprenoid side chain and biological activity, but can be converted to active vitamin K2, menaquinone, after alkylation in vivo. -- Pubchem; Despite the fact that it can serve as a precursor to various types of vitamin K, menadione is generally not used as a nutritional supplement. Large doses of menadione have been reported to cause adverse outcomes including hemolytic anemia due to G6PD deficiency, neonatal brain or liver damage, or neonatal death in some cases. Moreover, menadione supplements have been banned by the FDA because of their high toxicity. It is sometimes called vitamin K3, although derivatives of naphthoquinone without the sidechain in the 3-position cannot exert all the functions of the K vitamins. Menadione is a vitamin precursor of K2 which utilizes alkylation in the liver to yield menaquinones (MK-n, n=1-13; K2 vitamers), and hence, is better classified as a provitamin
