From a depth of nearly 2 miles beneath the earth's crust, the source of Ancient Minerals is drawn from the Ancient Zechstein Seabed, a geological formation in Northern Europe from the Late Permian Era. Isolated for the past 250 million years, Genuine Zechstein magnesium stands alone as the purest and most pristine source of natural magnesium chloride in the world, and a mark of purity on every bottle of Ancient Minerals.
