Structure of Coral – Calcium

Corals belong to the phylum (group) of marine organisms called Cnidaria (Coelenterata) which also includes jellyfish, sea anemones and hydroids. These organisms tend to be symmetrical with digestive tract that has one single opening. They process a “nematocyst” or stinging apparatus which contains and protects the coral polyp with venom of varying potency.

The stony corals are named because they secrete a supporting exoskeleton (outside hard structure). This stony covering contains the soft structures of the living coral polyps. These living corals form reefs which support a large biomass. In tropical waters and some temperate zones theses corals proliferate to a vast degree that builds islands.

A classic example of this geographical phenomenon is the infrastructure of the islands chains in and around Okinawa, Japan.

Coral calcium is derived from reef-building coral and it is harvested from the pristine waters off the Nansei Islands (Rukuyuku and Satsunan), Japan. These islands spread towards the south east from the southern tip of Japan’s main land mass towards Taiwan.  Using careful, harvesting techniques that are sustaining for the environment, several companies collect and process coral calcium for use as a food supplement. The Japanese government supervises this collection process and they provide special certification to certain types of coral.

Under a microscope, coral appears as tubes, horns and honey combs. It has the appearance of an abandoned city. Coral calcium has been officially recognized by the Japanese government as a valuable food supplement. This official standing was registered by Japan in July 1989, but the coral sands have enjoyed thousands of years of local use as an important source of health giving nutrients in the diet of Okinawans.

It was discovered by the early Spanish explorers, 500 years ago, who filled their ship holds with the coral sands. The chemists in Spain, attempting to discover the reason for its miraculous curative properties, discovered that the main ingredient was calcium, so they renamed it “coral calcium.” Today, tens of millions of people around the world consume coral calcium daily.

So, join us, one of the millions who use Coral Calcium to supplement our diets with essential minerals and nutrients only nature could provide.

Why Coral Minerals?

In my earlier writings, I have stressed the calcium factor for health and many of these issues will be further addressed in my books.  My belief in the role of coral minerals for health has come from many years of careful research and observation of its effects in thousands of individuals who have used coral products.  There is a voluminous amount of folklore, historical and scientific literature on stony corals and their biological implications, but I have been most impressed by its apparent universal health benefits which on occasion, almost defy explanation.  My support for the nutraceutical value of coral calcium is not a “leap of faith” based on my channeled research on calcium alone. When coral calcium from Okinawa and surrounding domains in Japan is used as a food supplement, it touches many lives in a highly positive manner.

In brief we can learn from the experiences of the inhabitants of Okinawa, who have among the best health and longest lives in the world, which include ten times as many centenarians as area found in the United States.  They also have large numbers of robust individuals in their eighties and nineties.  Whilst, many factors may operate to create this desirable circumstance, I, like the Spanish explorers before me, believe a key to this circumstance is the use of coral calcium as a food supplement in this highly blessed community of people.

Some people may dismiss this phenomenon as a chance observation, there are new scientific and medical discoveries that give a credible, scientific basis for the use of coral calcium for health.  One key constituent of coral calcium is readily absorbable calcium and magnesium, but other factors within coral, including its highly balanced mineral content and the occurrence of microbes, may account for observed benefits.  Beyond these issues are speculations about other components of coral and a clear recognition that many of the minerals are present in a “chemical form” that is highly desirable for use by the body.
