Coral calcium is promoted to a great extent as a superior form of calcium. Coral Calcium is a salt of calcium derived from coral reefs and fossilized coral reefs. Coral can be referred to as tiny sea animals related to jellyfish and sea anemones family. Coral forms a hard protective frame of calcium carbonate (CaCO3). When the coral dies, fresh geneses of coral grows on top of the calcium carbonate, finally forming a coral reef. Now days, coral reefs are categorized as endangered. Thus in many parts of the world they cannot be used directly. Whereas, grinding above-ground limestone deposits that were once part of coral reef is permitted. The coral calcium is primarily harvested from coral in Okinawa, Japan. The inhabitants of this region are said to live longer and have lower cases of heart diseases and cancerous development. Coral calcium constitutes of abundant amount of calcium carbonate and small amounts of essential trace minerals including boron, carbon, rubidium, iodine, magnesium, molybdenum, potassium, sulfur, vanadium, manganese, selenium, silver, chromium, copper and zinc.
Many believe that coral calcium is an excellent supplement due to the similarity of composition in many ways with the human skeleton. Discovery of coral calcium is considered by some as a major happening in the nutrient supplement industry. Other calcium supplements are effective but the human body is incapable of absorbing the nutrient content to its maximum. Whereas, coral calcium, since it comes from a natural source is considered to be healthier. This consideration is not backed by any scientific evidence, thus many still conceive it as a dubious supplement. This is a major cause why coral calcium is not popular. Many supporters claim that it is superior to any other form of calcium, but the evidence are not conclusive. Furthermore, people with shellfish allergies should not take coral calcium blindly.
The biggest supporter of coral calcium was Barefoot. He claimed that coral calcium cured diseases such as cancer, multiple sclerosis, lupus, heart disease and high blood pressure. His beliefs were critically picked apart. In 2003, he and his coral calcium supplement company faced legal complications from the Federal Trade Commission. However, claims in favor of coral calcium are that it is an excellent source of calcium and other essential nutrients. It promotes healthy oxygen levels in the body to help maintain immune system function and promote waste removal.
