The Ecology of Humans (46-6) Vitamin K


Vitamin K is a group of structurally similar, fat-soluble vitamins. Mammals need vitamin K for the cardiovascular system, building strong bones, and in some tissues.

Green leafy vegetables – such as spinach, collard greens, kale, asparagus, broccoli, and lettuce – contain vitamin K, as do soybeans, whole wheat, oats, seaweed, yogurt, and eggs.
