What Is Coral Calcium?
Coral Calcium is a generic term first used by marketing companies to describe the mineral substance sourced from coral.
Like any product, coral calcium can be found in many different places around the world in varying quality's. We choose to use only Okinawan marine grade coral calcium.
Okinawan Marine Grade Coral Calcium – is essentially coral that has broken off and fallen onto the seabed due to the natural weathering of coral reefs through wave action. The result of the weathering is a substance called coral sands. These coral sands are carefully vacuumed up from the sea bed, some 4 - 6 kilometers from the living reefs and are then washed, heated and crushed to a fine tasteless powder.
The beauty of the coral sands collected from Okinawa is that the Okinawan islands are formed from ancient volcanoes which are naturally very mineral rich areas and the mineral content of the coral sands collected from this area reflects this with higher levels of trace minerals than from other coral samples tested in other areas of the world including the Carribbean, Australia and Brasil.
Naturally the high calcium content of the coral sands comes from the exoskeleton of the once living coral (which is quite porous and also happens to be the closest constituent to the human bone and often used in surgery procedures) while the high magnesium is created by ionization of the marine coral calcium which occurs through an ion exchange between the coral sands and the surrounding waters over a process of time.
The most unique quality of marine coral calcium sourced from Okinawan coral sands is that calcium and magnesium are found in the perfectly balanced ratio of 2:1 (CaCo3,MgCo3) which is recommended by practitioners for best absorption of the two minerals.
The chemical formula of marine coral calcium (CaCo3,MgCo3) CaMg(CO3)2 also happens to be the same formula for dolomite (calcium and magnesium found naturally bound together in a 2:1 ratio) sourced from limestone and rock sources which has long been used by farmers to alkalize and "sweeten" the soils however frowned upon in recent times for human consumption due to the questionable amounts of heavy metals and the low absorption rate.
