Two Types Of Coral Calcium

There are two types of coral calcium that are used as health supplements throughout the world. The first type is called fossilized calcium. This type of calcium has been deposited on the land or washed up onto the ocean shores. The second type of coral calcium is taken directly from the beds of the sea. This type is called coral sand, and it has been brought to the floor of the ocean from the action of the waves. Seabed coral comes from the reefs in the ocean. It has either dropped from the reef or been processed by the inhabitants of the reef.

Although there are reefs throughout the oceans of the world, one of the most popular places to obtain coral calcium is Okinawa, Japan, which is located on the southern tip of Japan. Okinawa is made up of hundreds of coral reef islands. The coral calcium that is obtained from the underwater seabeds of Okinawa has the perfect natural balance of calcium to magnesium.

One of the most important differences between the fossilized coral, or land coral, and the marine, or seabed coral, is its composition. Fossilized coral contains less than 1% magnesium, while seabed coral contains 12%. This means that the balance of calcium, which is 24% in marine coral, to the magnesium is 2:1. This ratio of two to one for calcium to magnesium is the ideal ratio for human diet.

Many of the nutrients, including most of the magnesium, that were originally found in the coral before it became fossilized were lost during its weathering processes. This type of coral, which is collected from beach mines, has actually undergone thousands and thousands of years of erosion. There are actually some nutritional supplement companies that use the fossilized coral calcium that is collected from the ocean's beaches and add magnesium to it. They do this in order to achieve the two to one balance of calcium to magnesium that is the proper balance for their dietary supplements.

Although both fossilized and seabed calcium are considered coral calcium, consumers need to aware of the differences between them.
