China Manufacture Food Grade Menadione Vitamin K3

Product Description Menadione is an organic compound with the formula C6H4(CO)2C2H(CH3). It is an analog of 1,4-naphthoquinone with amethyl group in the 2-position. It is occasionally used as a nutritional supplement because of its vitamin k activity. It is sometimes called vitamin K3, although derivatives of naphthoquinone are not naturally occurring chemicals and therefore do not qualify as Vitamins, and without the side chain in the 2-position they cannot exert all the functions of the K vitamins. Menadione is metabolized by the human body into K2 which uses alkylation to yield menaquinones (MK-n, n=1-13; K2 vitamers), hence is better classified as a provitamin. menadione is generally not used as a nutritional supplement in economically developed countries. Menadione for human use at pharmaceutical strength is available in some countries with large lower income populations. It is used in the treatment of hypoprothrombinemia outside of the United States.
