Pink Himalayan salt, like all other forms of salt, is atomically 50 percent sodium and 50 percent chloride. However, by weight, sodium only makes up 40 percent of the compound. Trace amounts of other substances that differentiate salts make up less than 1 percent of it.
Pink Himalayan salt, which is mined in salt caves 250 million years old and kept unrefined and unprocessed, features a number of trace elements left in the final product. It even contains radioactive and poisonous materials like uranium, radium, polonium and thorium, albeit in amounts so small that they are essentially harmless. Many websites claim that pink Himalayan salt possesses 84 trace minerals that make up the human body, promoting health and well-being.
