Cauliflower is a cruciferous vegetable whose breakdown products (thiocyanates) can theoretically compete with iodine uptake by the thyroid. In practice, a 2024 systematic review found brassica vegetables at normal dietary intakes do not impair thyroid function when iodine is adequate, and because levothyroxine is hormone you swallow as a tablet, ordinary cauliflower portions do not meaningfully affect it.
