Himalayan rock salt is chemically similar to table salt. It contains up to 98 percent sodium chloride. The rest of the salt consists of trace minerals, such as potassium, magnesium, and calcium. These give the salt its light pink tint. These minerals also explain why Himalayan salt tastes different from regular table salt. Himalaya Rock Salt contains up to 98 percent sodium chloride, this means that only around 2 percent is made up of these various trace minerals. Given the relatively limited quantities in which people normally consume salt, and the tiny quantity of these minerals in the salt, they are unlikely to provide any measurable or significant health benefits.
