Vitamin K is rapidly metabolized and excreted. Based on phylloquinone measurements, the body retains only about 30% to 40% of an oral physiological dose, while about 20% is excreted in the urine and 40% to 50% in the feces via bile [ 2, 11 ].
What is vitamin K?
“Vitamin K,” the generic name for a family of compounds with a common chemical structure of 2-methyl-1,4-naphthoquinone, is a fat-soluble vitamin that is naturally present in some foods and is available as a dietary supplement [ 1 ]. These compounds include phylloquinone (vitamin K1) and a series of menaquinones (vitamin K2) [ 2 ]. Menaquinones have unsaturated isoprenyl side chains and are designated as MK-4 through MK-13, based on the length of their side chain [ 1, 2 ]. MK-4, MK-7, and MK-9 are the most well-studied menaquinones.
