Description

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.
