Coral Calcium Types – An Explanation
It is important to recognize that two broad, but distinct types of coral calcium, are used as health giving supplements by the Japanese and many people throughout the world.
The first type is fossilized coral calcium that has been deposited on the land mass, or washed up on the beaches. The second type is taken directly from the sea bed. The sea-bed coral calcium is the coral that has dropped from the reef or is processed by reef inhabitants. This type of “coral sand” has been washed to the ocean floor by wave actions. Marine coral calcium is closer in composition to the living forms of corals, because the marine microbes are still active and many minerals and organic elements are retained, in comparison to fossilized, land-based coral.
These are important differences in composition between fossilized (land-based) and marine (sea-bed) coral calcium. Marine coral calcium contains more magnesium, and the balance of calcium (24%) to magnesium (12%) content of this second type of marine coral is close to 2:1. This 2 to 1 ratio is the ideal ratio for calcium and magnesium intake in the human diet.
My research has led me to believe strongly that the natural, magnesium enriched, marine coral calcium is to be strongly preferred as a health giving supplement over land based (fossilized coral), which contains less than 1% magnesium. This superiority of the marine coral is due to its retained, ideal, ionic balance of calcium and magnesium in a 2:1 ratio, and the fact that for the fossilized type, a host of other nutrients were also washed out during weathering processes.
