Interestingly, the synthetic form of vitamin K-menadione-appears in the cell during the metabolism of phylloquinone and is a precursor of MK-4, a form of vitamin K2 inaccessible in food. A healthy diet rich in fruit and vegetables ensures an optimal supply of K1 and K2, though consumers often prefer supplements. A dietary intake of K1 is inversely associated with the risk of pancreatic cancer, K2 has the potential to induce a differentiation in leukemia cells or apoptosis of various types of cancer cells, and K3 has a documented anti-cancer effect. However, recent epidemiological studies suggest that vitamin K has various benefits that go beyond blood coagulation processes. The group comprises phylloquinone (K1)-a 2-methyl-3-phytyl-1,4-naphthoquinone menaquinone (K2, MK)-a group of compounds with an unsaturated side chain in position 3 of a different number of isoprene units and a 1,4-naphthoquinone group and menadione (K3, MD)-a group of synthetic, water-soluble compounds 2-methyl-1,4-naphthoquinone. Vitamin K is the common name for a group of compounds recognized as essential for blood clotting.
