Vitamin K

[byungin]

The naturally occurring forms of vitamin K are all fat soluble. They are stored in the liver, though not to any great extent. Stable to heat and reducing agents, they are destroyed by light, acid, alkali, oxidizing agents, and alcohol.
Most supplemental forms of chlorophyll, as a vitamin K source, are water soluble. Leafy green vegetables are the single best dietary source of vitamin K because of their high chlorophyll content. Probiotic flora in intestines with a healthy ecology normally manufacture vitamin K.
There exist two naturally occurring forms of vitamin K: phytonadione or phylloquinone (Aquamephyton), and menaquinone. Phylloquinone, also called as vitamin K1, is synthesized in plants. Menaquinone, also known as vitamin K2, is synthesized by bacteria. The vitamin is not used for blood clotting in plants and bacteria, as these forms of life do not have blood. Instead, the vitamin is used for electron transport and energy production. [p324]
