Vitamin K

Vitamin K is needed in the production of several proteins necessary for blood clotting. It is also essential for the formation and repair and bones and teeth. This is because it is used for synthesis of osteocalcin, the protein in bone tissue on which calcium crystallizes. Vitamin K may also play a role in the intestines and help to maintain healthy liver function.

Vegetables are the best sources of vitamin K, though it is also found in meat and dairy products. Natural food sources include dark green leafy vegetables, asparagus, cabbage, cauliflower and oatmeal. The bacteria lining the gastrointestinal tract also produce vitamin K.

There is no recommended daily allowance for vitamin K, but most adults require 60-80 mcg daily.
