Vitamin K2 also known as menaquinone, is synthesized by the bacteria in the gastro-intestinal tracts. K2 is absorbed and sent to the blood vessel walls, bones and tissues excepting the liver.
Vitamin K, primarily in the form of phylloquinone, is absorbed in a form which is chemically unchanged after solubilisation. The absorption takes place in the proximal part of the intestine after bile salts and products of pancreatic lipolysis, form micelles with the soluble form of phylloquinone.
Vitamin K along with Vitamins A, D and E are fat-soluble vitamins. Therefore, they are most commonly stored in the fatty tissues of the human body.
Vitamin K is important for bone health and healing of wounds
