1 interaction related to sauerkraut
Sauerkraut is fermented green cabbage and contains roughly 18 to 70 micrograms of vitamin K1 per cup, depending on whether the brine is consumed and how the cabbage was prepared. Vitamin K1 supplies the cofactor for the very clotting factors warfarin blocks, so changing sauerkraut intake can shift INR and weaken anticoagulation control.
