Description

Vitamin K originates from the German term koajulation. It is also known as antihemorrhagic factor, and is one of the four fat-soluble vitamins necessary for good health. The others are vitamins A, D, and E. The primary and best-known purpose of vitamin K is support of the process of blood clotting. Prothrombin and other clotting factors are dependent on vitamin K for production. It also plays a role in bone health, and may help to prevent osteoporosis. Appropriate growth and development are supported by adequate vitamin K.

There are several forms of the vitamin:

• K₁ or phylloquinone; also known as phytonadione
• K₂, a family of substances called menaquinones
• K₃ or menadione, a synthetic form of this vitamin
