Vitamin K

Vitamin K is a fat-soluble vitamin that the human body needs for protein modification for blood clotting and for binding calcium in bones and other tissues. Vitamin K is found throughout the body including the liver, brain, heart, pancreas, and bone. Two types of vitamin K exist – K1 (phylloquinone) and K2 (menaquinones). Vitamin K1 is mainly found in leafy green and other vegetables while K2 comes from animal products like meat, cheese and eggs. Vitamin K is typically present in multivitamin supplements, in standalone products or in combined products that include other nutrients such as calcium, magnesium, and/or vitamin D.
