cabbage
2 interactions related to cabbage
cabbage + levothyroxine
Cabbage and other brassica vegetables release thiocyanates and goitrin that can compete with iodide uptake at the thyroid and interfere with hormone synthesis. In normal, mostly-cooked portions this has no meaningful effect on levothyroxine in iodine-sufficient adults. Concern is limited to very large, sustained raw-cruciferous intakes or iodine-poor diets.
sauerkraut + warfarin
Sauerkraut is fermented green cabbage and is a moderate source of vitamin K1, the nutrient that warfarin works against. Because vitamin K supplies the cofactor for the very clotting factors warfarin blocks, suddenly starting, stopping, or swinging your sauerkraut intake can shift your INR and loosen anticoagulation control. The goal on warfarin is consistent intake, not avoidance.
