To make Whole Earth & Sea Deep Ocean Minerals, deep ocean water is drawn from a depth of 662 meters in a pristine location protected by steep mountains. The minerals and trace elements are extracted using a patented production process. Deep Ocean Minerals contains essential minerals and trace elements, including magnesium, which catalyzes over 300 enzyme reactions. These macro-minerals and trace elements give structure to our organs, tissues, and bones, and help maintain fluid balance, pH balance, and membrane permeability.
