Vitamin K antagonists interfere with the synthesis of vitamin K-dependent clotting factors in the liver, according to secondary sources. Several medications, including warfarin, have been developed for venous thromboembolism [​1​]. Vitamin K may decrease the blood-thinning effects of vitamin K antagonists and will therefore lower the PT or INR value, increasing the risk of clotting. Therefore, people taking warfarin are usually counseled to keep dietary vitamin K levels consistent and to avoid vitamin K supplements. Conversely, vitamin K is used to treat overdoses or any excess anticoagulant effects of warfarin and to reverse the effects of warfarin prior to surgery or other procedures. Over-the-counter vitamin K1-containing multivitamin supplements decrease warfarin anticoagulation in vitamin K1-depleted patients. Vitamin K-depleted patients are sensitive to even small changes in vitamin K1 intake. In humans, oral or intravenous vitamin K were shown to decrease elevated PT or INRs associated with warfarin use [​2​;​3​], but the effects on induced coagulopathy are not clear [​4​]. In humans, low-dose oral vitamin K (1.25mg) did not reduce bleeding in warfarin recipients, with INRs of 4.5-10.0 [​5​]. Results from a meta-analysis showed that polymorphism of the vitamin K epoxide reductase complex subunit 1 (VKORC1) played a role in the warfarin dosage requirement [​6​]. According to the authors of reviews, manipulation of dietary vitamin K levels is an option for managing stability of oral anticoagulant therapy [​7​;​8​]. In human research, oral vitamin K was not shown to affect the pharmacokinetics of S- and R-warfarin [​9​].
