"Candida (systemic yeast) infections have been linked to vitamin K deficiencies. An overgrowth of candida albicans or other kinds of yeast can crowd out the helpful bacteria in the digestive tract that make vitamin K. People who eat a lot of sugary foods, an unusually high proportion of alkaline foods and/or take antibiotics tend to be at high risk for Candida infections.


Malabsorption syndromes that prevent the proper absorption of nutrients can cause vitamin K deficiencies. Celiac disease, an intolerance to gluten, can cause deficiencies of a wide variety of nutrients, especially vitamin K. Crohn's disease can also cause vitamin K and other deficiencies. "
