Vitamin K and The Body

Vitamin K is important for blood clotting and the proper functioning of proteins involved in bone metabolism. Vitamin K is a fat-soluble vitamin that is absorbed in the small intestine and stored in the liver, where it helps to create several proteins required for proper blood clotting and bone mineralization. Vitamin K works by activating a group of enzymes known as vitamin K-dependent coagulation factors, which are responsible for helping to form clots when the body needs them.

The body can produce Vitamin K through bacterial fermentation in the intestines. However, it's still important to consume enough of this vitamin through the diet. Sources of Vitamin K include green leafy vegetables such as; spinach, chard, kale, and romaine lettuce. Vitamin K is also found in broccoli, green cabbage, and olive oil. Eating a variety of foods that contain vitamin K can help ensure adequate intake. The Adequate intake (AI) for Vitamin K is 90 mcg for adults, this level varies during certain lifecycles.

Disclaimer: If you are taking Warfarin/Coumadin, it's important to speak with your doctor before making any changes to your diet. It is possible that consuming too much or too little vitamin K could affect your medication's effectiveness.
