According to a 2023 study published in *Food & Nutrition Research*, the average concentration of iodine in a cup of black, filtered coffee is only about 0.086 micrograms per 100 mL. This means that for the vast majority of consumers, coffee is a negligible source of this essential mineral. The total iodine content is primarily influenced by the water used for brewing and any additives like dairy or fortified plant-based milk.
