Description and class
Vitamin K is popularly known as the blood clotting vitamin.
It is a group of fat-soluble vitamins. It exists in two main forms:
K1 - phylloquinone
K2 - menaquinone phylloquinone
Phylloquinone is the main dietary form of vitamin K found in green leafy vegetables.
Your body stores vitamin K in the liver, brain, heart, pancreas and bones. So, you may not need to eat large amounts of vitamin D.

Sources
Ugu (pumpkin leaves), fermented soybeans, locust beans, e.g., ogiri and iru, cabbage and cow liver are rich sources of vitamin K.
