A pure and naturally condensed source of Zechstein Inside Magnesium Chloride. Magnesium encourages the body to absorb calcium which could otherwise, over time result in a build-up within soft tissue and muscles, causing them to harden, restricting flexibility and function. Magnesium Flakes contain 47% magnesium chloride and when bathed in, delivers this essential mineral directly into the skin tissue, entering cells immediately, efficiently replacing magnesium lost through modern diet and pressured lifestyles.
