The objective of this study is to summarize the current evidence supporting the putative interaction between dietary vitamin K intake and changes in INR with the VKAs. All clinical studies investigating the relationship between dietary vitamin K and measures of anticoagulation were included. We excluded all studies of supplementation of vitamin K alone.
This study aimed to explore the correlation between usual vitamin K intake and response to anticoagulant therapy among patients under warfarin therapy. Clinical information and laboratory parameters were sourced from medical records. Dietary vitamin K intake was assessed using a semi-quantitative food frequency questionnaire that has been developed for the purpose of assessing dietary intake of vitamin K. A total of 50 patients aged between 21 and 87 years were included in the study. The mean vitamin K intake was Study subjects were divided into tertiles according to their usual vitamin K intake.

Vitamin K refers to structurally similar, fat-soluble vitamers found in foods and marketed as dietary supplements. The presence of uncarboxylated proteins indicates a vitamin K deficiency. Carboxylation allows them to bind chelate calcium ions, which they cannot do otherwise. Research suggests that deficiency of vitamin K may also weaken bones, potentially contributing to osteoporosis , and may promote calcification of arteries and other soft tissues. Chemically, the vitamin K family comprises 2- methyl - 1,4-naphthoquinone 3- derivatives. Vitamin K includes two natural vitamers: vitamin K 1 phylloquinone and vitamin K 2 menaquinone. The two most studied ones are menaquinone-4 MK-4 and menaquinone-7 MK
