Vitamin K

Vitamins (VYE-ta-mins ) are compounds that you must have for growth and health. They are needed in only small amounts and usually are available in the foods that you eat. Vitamin K is necessary for normal clotting of the blood. Vitamin K is found in various foods including green leafy vegetables, meat, and dairy products. If you eat a balanced diet containing these foods, you should be getting all the Vitamin K you need. Little Vitamin K is lost from foods with ordinary cooking. If you are taking anticoagulant medicine (blood thinners), the amount of Vitamin K in your diet may affect how well these medicines work. Your doctor or health care professional may recommend changes in your diet to help these medicines work better. Lack of Vitamin K is rare but may lead to problems with blood clotting and increased bleeding. Your doctor may treat this by prescribing Vitamin K for you. Vitamin K is routinely given to newborn infants to prevent bleeding problems. Vitamin K is available only with your doctor's prescription, in the following dosage forms: Oral Phytonadione Tablets (U.S.) Parenteral Phytonadione Injection (U.S.)
