Vitamin K is a nutrient your body needs for blood clotting and a number of other important functions. A lack of Vitamin K can cause bruising and bleeding problems because blood will take longer to clot. If you are taking a blood thinner, it’s especially important to get a sufficient amount of vitamin K each day.
Vitamin K is also needed to make proteins that affect bones and cartilage. It helps keep cartilage from calcifying. Calcified cartilage contributes to osteoarthritis in the joints. Severe vitamin K deficiency can also lead to osteoporosis, or weakening of the bones.
Research has also shown that too little vitamin K may be related to various age-related concerns, such as cognitive function and heart disorders. Many older adults get less vitamin K than they should, so they’re more likely to have difficulty being physically active.
The amount of vitamin K you need depends on your age and gender.
