Vitamin K Molecule

Vitamin K is a fat-soluble vitamin that plays a critical role in the function of several proteins involved in normal blood clotting. It also assists in the promotion of bone health. There are two natural forms of Vitamin K: Vitamin K1 and Vitamin K2. Vitamin K1, or phylloquinone, is synthesized by plants. Vitamin K2, or menoquinone, is created by bacteria in the small intestines. The three synthetic forms of Vitamin K are K3, K4, and K5.

It`s rare to have a Vitamin K deficiency since bacteria in the intestines can make the vitamin. However, since intestinal bacteria populations are low at birth, newborns are commonly administered a Vitamin K injection. Food sources rich in the vitamin include beef liver, green tea, turnip greens, broccoli, kale, spinach, cabbage, asparagus, and dark green lettuce.
