Caution if You Take Anticoagulants

Individuals taking certain anticoagulants benefit from consistent levels of vitamin K in their diets. Because vitamin K helps with clotting, patients on some anticoagulant medications are often advised to avoid excessive consumption of vitamin K-rich foods like leafy green vegetables.1DiNicolantonio, James, Jaikrit Bhutani and James O’Keefe. ‘The Health Benefits of Vitamin K.’ Open Heart, vol. 2, no. 1, 2015. www.ncbi.nlm.nih.gov/pmc/articles/PMC4600246/ That's because excess vitamin K reduces the efficacy of blood thinners like warfarin.

Patients on anticoagulants should eat consistent amounts of vitamin K foods to balance the effects of anticoagulant medications on the body.1DiNicolantonio, James, Jaikrit Bhutani and James O’Keefe. ‘The Health Benefits of Vitamin K.’ Open Heart, vol. 2, no. 1, 2015. www.ncbi.nlm.nih.gov/pmc/articles/PMC4600246/
