                                According to the National Institutes of Health, vitamin K deficiency is quite rare among healthy adults in the United States, but certain health conditions and medications can dramatically reduce its absorption. This includes any condition that interferes with fat metabolism, as vitamin K is a fat-soluble vitamin and requires fat for proper absorption.
