Vitamin K Deficiency
Besides new born infant, vitamin K deficiency can also occur in adults and especially those people who are treated with some antibiotics medication. Blood coagulation protein known as prothrombin is the most affected by vitamin K insufficiency.
The recommended dietary allowance (RDA) for this fat-soluble vitamin is 80 mg /day for adult man, for adult woman it is 65 mg/day while for babies it is 5 mg/day. Vitamin K whose source is plant foods is known as phylloquinone while the form of vitamin K found in animal food is known as menaquinone. Both these forms are collected from the food and changed into an active form known as dihydrovitamin K.
Bacteria living in the intestine also provide a portion of the body’s vitamin k.
