Health Benefits of Vitamin K

Vitamin K is essential for proper blood clotting, but it also provides additional benefits that make it a necessary nutrient for everyone.  Adding vitamin K to the diet can be done by adding foods rich in this vitamin to meals and snacks. 


The World's Healthiest Foods database ranks sources of vitamins as excellent, very good or good depending on their nutrient content.  Excellent sources of vitamin K include kale, spinach, parsley, turnip greens, mustard greens, collard greens, dried basil, Romaine lettuce, Swiss chard, thyme, broccoli, Brussels sprouts, asparagus, green beans, cauliflower, tomatoes, cabbage, celery, oregano and kelp.  Very good sources of vitamin K include black pepper, cloves, carrots, green peas, bell peppers and summer squash.  Good sources of vitamin K include kidney beans, strawberries, pears, papaya, pumpkin seeds, cow's milk, avocado, miso and cayenne pepper. 

Health Benefits 

Vitamin K has a number of important health benefits and plays a role in treating or preventing several health conditions.  This vitamin can be used to treat anticoagulant overdose, which is an overdose of blood thinners that can cause excessive bleeding or death.  Vitamin K helps the blood to clot normally, which can counteract the effects of a high dose of anticoagulants.  Easy bruising can also be prevented by eating foods rich in vitamin K.  Easy bruising can occur when the blood does not clot normally.  Supplementing your diet with foods high in vitamin K can help restore the blood's ability to clot normally, preventing easy or frequent bruising.  Vitamin K is also used to help treat or prevent heart attack, cancer, kidney stones, menstrual pain, osteoporosis, rheumatoid arthritis, stroke and pulmonary embolism. 


Consuming vitamin K in its natural form does not seem to cause any adverse effects in healthy people.  However, people with clotting disorders should consult their physicians before adding vitamin K to their diets.  Always consult a physician before taking a supplement if you have a chronic disease that makes it necessary to carefully plan your diet and restrict specific foods.  Ingesting too much of the supplement for of vitamin K can result in symptoms of toxicity.  Studies have revealed that vitamin K toxicity can result in the excretion of antioxidants from the body, which allows free radicals to cause cellular damage.  Hemolytic anemia and jaundice have also been associated with vitamin K toxicity caused by a form of supplement.  The FDA does not allow this form of vitamin K in supplements, so avoid supplements from other countries, which may not be as closely regulated.
