Nutritionally, Himalayan salt is much like regular table salt. A study in Australia found that Himalayan salt contains higher levels of various elements, including calcium, iron, magnesium, manganese, potassium, aluminum, barium, silicon, and sulfur, and lower sodium levels compared to table salt. However, the study suggested that consuming "exceedingly high amounts" (almost 600% more than the recommended daily salt intake) would be needed for these differences to matter. At such high levels, any potential nutritional benefits would be outweighed by the risks of consuming too much sodium. One crucial difference is in iodine content. Many table salts are iodine-supplemented, helping prevent iodine deficiency disorders. Himalayan salt lacks this iodine supplementation.
