DescriptionVitamins (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.
This medicine is available only with your doctor's prescription, in the
