Adults should consume 90–120 mcg of vitamin K per day for women & 120–150 mcg for men. Although vitamin K deficiency is uncommon, it can happen to people who have specific medical conditions or are taking specific medications.
Since it may conflict with some medications, taking too much vitamin K in the form of supplements is generally not advised.
