Since iodine is not produced endogenously, it must be acquired from external sources. Owing to the very low concentration of iodine in natural foods, it needs to be supplemented by other means so as to avoid iodine deficiency which has become a global public health concern. Iodization of table salt becomes a simple and effective program to prevent the iodine deficiency disorderssuch as goitre, hypothyroidism and retarded psychomotor development in infants.  The growing popularity of “natural” rock salt and sea salt variants which often lack adequate amount of iodine poses a significant challenge in maintaining the iodine levels in our body. This article explores the iodine concentration in various commercially available salts, thereby highlighting the stark contrast in their iodine levels.The iodine content of a range of commercially available salt samples was quantitatively determined by iodometric titration. Among the fifteen branded samples analysed, only five iodised variants exhibited iodine concentrations approaching the recommended level specified by the World Health Organization (WHO) (≥ 15 ppm at the point of consumption). In contrast, non-iodised salt varieties, including black salt, rock salt, and pink salt, demonstrated negligible to undetectable iodine levels.With these findings the article aims to raise awareness and also address the misconceptions about the health benefits of non-iodized natural salt varieties while emphasizing the need for iodine fortification. The article also delves into the need for proper storage of the iodized salt to minimize the sublimation of iodine from the sample. Through scientific data this research article aims to promote awarenessregarding the essential role of iodine in human nutrition so that consumers are able to make informed choices pertaining to salt storage and consumption. https://www.foodandnutritionjournal.org/vol14nospl-issue-sustainable-nutrition-2026/from-salt-to-health-iodine-content-in-market-available-salts-and-its-significance/ Awareness Deficiency Diseases Iodine Salts Storage Sublimation
