Coral calcium is a salt of calcium derived from fossilized coral reefs. Living coral reefs are endangered and cannot be harvested without severe damage to the ecosystem, so coral calcium is harvested by grinding up above-ground limestone deposits that were once part of a coral reef.
Biology
While the calcium component of coral calcium is identical to any other limestone deposit, fossilized coral reefs may contain trace minerals helpful to the human body, though it's unlikely that a well-fed individual would be deficient in any of these minerals.
There have been many unsubstantiated claims made regarding coral calcium, perhaps the most controversial of which is that taking coral calcium can cure cancer by increasing "body pH." Scientific studies have been performed indicating that cancer cells cannot survive at sufficiently high pH (or alkalinity) levels. What the marketers of coral calcium usually fail to mention is that these studies were conducted in-vitro and not in any living animal. The reason for this is that the pH required to kill cancer cells also kills healthy human cells.
Another problem with the "body alkalinization" idea is that the body pH doesn't change, regardless of how much calcium carbonate is ingested. The human body can only function properly within a narrow pH range, and if alkalinizing agents such as CaCO3 are ingested, the body promptly excretes the alkaline components in urine. So, people who attempt to increase the pH of their bodies are really only succeeding in raising the pH of their urine. The same applies if acidic foods are ingested in that the urine becomes more acidic.
Calcium itself is an essential mineral for human life, and coral calcium is an effective source of it, though by no means the only one.
