This paper is devoted to the study of iodine-containing mineral spring drinking waters identified in the Kaspi district of Georgia and to the assessment of their practical significance for public health. In six springs, across all four seasons of the year, the iodide-ion content was determined by a kinetic method, while the overall chemical composition was established using methods compliant with ISO standards. It was found that the iodine concentration in the springs ranges from 16–54 ug/L and follows a pronounced seasonal dynamic, being minimal in spring–summer and maximal in winter. The waters are practically neutral (pH 7.48–7.69) and fall within the normal range of mineralization. The findings are discussed in comparison with existing methods of iodine-deficiency-disorder prevention (iodized salt, iodide preparations), demonstrating the advantage of iodine-enriched drinking water as a safe and physiologically effective alternative. The study highlights the potential of the mineral waters of the Kaspi district as a natural resource for supplying the population with iodine.
