Vitamin K2

Vitamin K is a liposoluble molecule discovered by Danish scientist Henrik Dam in 1929. From a biochemical point of view, vitamin K is a quinone, more precisely a naphthquinone. The basic biochemical action of vitamin K is the carboxylation of glutamic residues of various proteins (Vitamin K-Dependent Gla Proteins) at the microsomal level. Protein carboxylation is a potent stimulating mechanism of calcium binding ability of the protein itself.

Vitamin K2 acts by activating a specific protein (Osteocalcin) that stimulates the incorporation of calcium into the bones and teeth.

Dalla sua scoperta, la vitamina K è stata da subito associata alla soluzione di problemi coagulativi.
