Interaction warnings

Cabbage + levothyroxine

low

Cabbage releases thiocyanates from glucosinolates that compete with iodide uptake at the thyroid sodium-iodide symporter. Case reports tie very heavy raw cabbage intake (1+ kg/day) to severe hypothyroidism, but typical cooked portions do not measurably affect levothyroxine requirements when iodine is adequate.
