The magnesium chloride deposits from the former Zechstein Sea are considered to be the purest natural source of the highest grade of magnesium chloride worldwide. A special technology enables this raw material under contribution of water to be extracted as a super-saturated magnesium chlorid solution, the so called magnesium oil.

Due to its exceptional purity Zechstein Magnesium Oil is approved as a ready-for-use solution for applications in the health and sports sector without further processing. Zechstein Magnesium Oil is continuously subjected to chemical analysis. In this way the purity and quality of each batch is documented and verified. This proven and certified magnesium oil quality is known as "Zechstein Inside".
