Mineral Makeup of Seawater
Our products come from the pristine oceans of Australia, the Southern Ocean and/or the Pacific Ocean near the Great Barrier Reef. We do regular testing of our products and all fall well within the regulatory requirements. The following information is here as a guide only.
