Pink Himalayan salt has huge amounts of magnesium, sodium, potassium and other electrolytes essential for the body’s basic activities. It is also rich in iron, an important mineral for blood circulation and general vascular health integrity. Even calcium, which is a vital mineral for bones strength and well-built structure, is present in abundance. Salt is also called sodium chloride (NaCl). It consists of 40% sodium and 60% chloride, by weight. Salt is by far the biggest dietary source of sodium, and the words “salt” and “sodium” are often used interchangeably.
