Health Information

Vitamin K is needed for the production of prothrombin, which is necessary for blood clotting. It is also essential for bone formation and repair; it is necessary for the synthesis of osteoclasia, the protein in bone tissue on which calcium crystallizes. Consequently, it may help prevent osteoporosis. Vitamin K plays an important role in the intestines and aids in converting glucose into glycogen for storage in the liver, and promoting healthy liver function. It may increase resistance to infection in children and help prevent cancers that target the inner linings of the organs. It aids in promoting longevity. A deficiency of this vitamin can cause abnormal and or internal bleeding.

Vitamin K exists in three forms. Vitamin K1 (phylloquinone or phytonactone) and Vitamin K2 (a family of substances called menoquinones) occur naturally; vitamin K3 (menadione) is a synthetic substances.

Vitamin K is found in some foods, including asparagus, blackstrap molasses, broccoli, Brussels sprouts, cabbage, cauliflower, dark green leafy vegetables, egg yolks, liver, oatmeal, oats, rye, safflower oil, soybeans, and wheat. Herbs that can supply Vitamin K include alfalfa, green tea, kelp, nettle, oat straw, and Shepard's purse. However, the majority of the body's supply of this vitamin is synthesized by the friendly bacteria normally present in the intestines.

Antibiotics increase the need for dietary or supplemental Vitamin K. Because Vitamin K is synthesized by bacteria in the intestines, taking antibiotics - which kill the bacteria - interferes with this process. Antibiotics also interfere with the absorption of vitamin K. Drinking tap water (containing fluoride and choline) depletes intestinal bacteria needed for vitamin synthesis.
