Vitamin K is essential for the body's blood clotting process. Studies show that it might be helpful in protecting against Alzheimer's disease and osteoporosis and may even protect against certain cancers and heart disease. According to the National Institutes of Health, healthy adults should get around 90 micrograms of vitamin K every day; as long as no anticoagulant drugs are used, there is no risk of vitamin K toxicity and side effects. It is important to keep the vitamin K levels in the blood as consistent as possible to limit bruising or bleeding.
In general, vitamin K is found in green leafy vegetables such as kale, spinach, mustard greens and romaine lettuce. Fish, liver, eggs and meat also contain high amounts of the vitamin.
Vitamin K deficiencies are rare, but may occur after long-term antibiotic use or other reasons why the vitamin cannot be absorbed through the intestinal tract. Although supplements help, it is always better to get vitamins through food, when possible.
Since vitamin K is made by the bacteria in the gut, boosting the good bacteria by regularly consuming probiotic yogurt may also help boost vitamin K levels.Learn more about Food Facts
