What do they mean by “Marine Grade” Coral?
Marine grade coral calcium is the natural coral grains that have accumulated in the Okinawa tidal basin over the millennia. Due to the unique dynamic of the eco system (virtually no wave action) there is a vast supply of these mineral rich grains to be harvested. Coral calcium is composed primarily of the shells and skeletons of reef-building coral and microscopic sea life such as star sand that inhabit the area. To form their shells and skeletons, these organisms ingest minerals (mainly calcium and magnesium) from the ocean. As a result, the grains are mainly calcium, but they are also abundant in many sea minerals important to maintain good health. [Karl Note: The above description also includes the misleading information that “coral” consists of the shells and skeletons of living organisms. The truth is above, that “coral” is just rock that builds on itself by a mechanism that does not involve any living creature, but may involve the excrement of living creatures..
