Himalayan Rock Salt is packed with minerals often not found in any other form of salt. It is over 250 million years old, which means that it’s absolutely free from toxins and pollutants, and also offers all of the natural elements that are identical to the 84 elements in your body. Think of it as a bio-identical supplement that your body is able to instantly recognize and utilize. Having said that, you should also be aware that there are some concerns about the purity of Himalayan rock salt, now that it’s becoming so popular and readily available. If you’re concerned over toxic load, and unsure of the source of your salt, you’re likely better off with a gray sea salt.
