Warfarin and Vitamin K
People taking warfarin (Coumadin) are at higher risk for atherosclerosis and osteoporosis (brittle bones) because the drug increases arterial calcification and decreases bone calcification. A study in the journal Pharmacotherapy demonstrated the safety and benefit of low-dose vitamin K supplementation in patients taking warfarin. However, it is imperative that a person who takes blood thinners use vitamin K2 only under the close supervision of a doctor.
