Vitamin K is an essential nutrient for blood clotting. The vitamin maintains normal blood clotting by helping the body transport calcium to the specific area it may be needed. It has also been shown to promote bone health by reducing bone loss and lowering the risk of bone fractures.

How to know you may be getting too little:
Vitamin K deficiencies are quite rare, but far from unheard of. Increased bleeding, defective blood clotting in cuts or scrapes, and osteoporosis are all signs of a potential vitamin K deficiency.

What foods are high in vitamin K:
Vegetables such as spinach, broccoli, Brussels sprouts, wheat bran, and cauliflower are all very high in vitamin K.

Can you ever have too much?:
Although there have been no known toxic effects of too much vitamin K, it is possible that the nutrient in large doses can cause numbness or tingling in the extremities.
