So what is vitamin K?

Sometimes called the “clotting vitamin,” vitamin K is required for the blood to clot properly and also helps with bone formation and promotes bone health. Naturally found in a variety of foods, including leafy green vegetables and liver, vitamin K is also produced by the bacteria in your intestinal tract during digestion. Because vitamin K is fat-soluble, it is stored by your body, making it is possible to take in too much vitamin K.

As it helps with blood coagulation, vitamin K can affect how useful aspirin or other blood-thinning medications can be. If you consume a diet high in vitamin K-rich foods, or if you are taking a supplement of vitamin K, consult your doctor prior to taking medications to help prevent clotting to avoid possible complications. Vitamin K can also adversely interfere with some antibiotics, as well as certain weight-loss drugs, such as olestra. In the case of the latter, these weight loss drugs inhibit your body’s fat absorption ability, rendering it more difficult for your body to absorb, or retain, vitamin K.

Because vitamin K is fat-soluble, kidney dialysis will not flush the vitamin out of your system. Vitamin K is also not effective in treating clotting problems resulting from severe liver disease. Because vitamin K may inadvertently cause more damage to a diseased or damaged liver or kidney, if you suffer from kidney or liver disease, avoid taking vitamin K supplements and consult with your doctor concerning vitamin K in your diet.

In a nutshell, “moderate Kale consumption if you suffer from kidney or liver disease, else enjoy the immense health benefits it can bring!”
