Caution: If you are pregnant, may become pregnant, breastfeeding, or if you are taking anticoagulant drugs such as warfarin (Coumadin), consult a healthcare practitioner before using. Vitamin K2 may counteract the effects of anticoagulation therapy, and therefore is not recommended for patients on blood-thinning medications.
