There are huge discrepancies surrounding this issue. The harvesting is strictly supervised by the Japanese government.

There has been a recent surge of promotion selling "coral calcium pills". Selling ground up coral skeleton as a natural source of calcium is an endlessly recurring scam that hucksters pick up on every few years like clockwork. My colleague Wolf Hilbertz has a bottle of coral tablets someone was peddling in the 1960s. There are many natural sources of dietary calcium that don't require killing corals. It is important to keep a balance between your calcium and magnesium intake.

Reefs die for many reasons: rising water temperatures, sewage, eutrophication, disease and negligence. A reef ecosystem that took hundreds of years to grow can be destroyed in a single afternoon by dredging, dynamite or cyanide fishing. Corals around the world have been severely affected by global warming. High temperatures cause corals to turn white (or "bleach"). If it remains too hot for too long, the corals die of heat shock.

The longevity myth of Okinawa have been around for centuries. It did not get attention from the West until recent years. After years of research, scientists have successfully identified one of the key factors that contribute to the unusually healthiness of the Okinawans: the drinking water in Okinawa contains organic calcium compounds that are highly absorbable.

Calcium is needed for strong bones, teeth, and other various functions within the body. However, what many don’t know is that calcium also raises the body’s alkaline (pH) level. Many studies have been conducted on the pH level within the body, which many noted that healthy individuals boast high pH levels. The studies also showed that sick and diseases-ridden individuals have low pH levels.

Coral Calcium is ionized (that is, it has a positive charge which attracts it to the negatively charged wall of the large intestine where food absorption takes place) and it has particles about 1000 times smaller than most Calcium Chelates and Colloids, hence it absorbs right into the blood stream in only 15 minutes compared to about 20 hours for other types of Calcium. Yes, there is a direct correlation between calcium ion levels and pH.

Coral Calcium may, in effect, help prevent many diseases. With a rise of calcium in the body, the pH level is lowered. The pH level, or the level of acidity greatly influences the chances of illness taking place. The coral calcium acts as a buffer, or "naturalizes" pH levels. Coral calcium may help fight cancer, diabetes, osteoporosis, hypertension, cholesterol, arthritis, and fatigue to name a few.

No, Coral Calcium has been known to assist in balancing the pH level of the body creating an environment where the body can heal itself.

There are over 70 trace minerals found in coral calcium some of which are Zinc, Iron, Potassium, Magnesium and Selenium.

Coral Calcium is structured almost identically to the calcium found in your bones and teeth. The body doesn’t have to break down the coral calcium and restructure it into its own calcium. In essence, you can say that coral calcium is the same substance as the calcium you’ll find in your bones.

Typically vessel sewage impacts manifest themselves in the form of excess nutrients and pathogens in the water column. In poorly flushed areas, such as bays and inlets, this results in excess macro-algae growth that will smother corals and impede their growth. It will also result in an excess of micro-algae or phytoplankton growth. These phytoplankton blooms may pose a health risk to humans while also being toxic to other species.

No, There are at least four products being sold as Coral Calcium.. There is a wide variance between products.

The main indicator of quality is accepted to be the raw material with the highest amount of natural occurring minerals.
