Calcium is an essential mineral and is required for human life. However talk about the benefits of coral calcium can be confusing and may make it difficult to put into context how we can benefit from appropriate levels of calcium in the diet, be it from food or from supplemental sources.
Calcium is the most abundant mineral in the human body, and has several important functions. More than 99% of total body calcium is stored in the bones and teeth providing the necessary support to their structure. As a normal function of biology, the living cells of the body absorb new calcium to replace lost calcium or to build upon existing structure as in the case of childhood growth or in healing.
Coral calcium is a salt derived from fossilized coral reefs. The living coral reefs are endangered and most major reefs are protected by law as they cannot be harvested without severe damage to the ecosystem. Coral calcium is harvested by grinding up above-ground limestone deposits that were once part of a coral reef.
Coral calcium itself is composed primarily of calcium carbonate with small amounts of magnesium and other trace minerals. Chemically, calcium carbonate from coral sources is no different than from other sources of calcium, despite the claims otherwise by some companies. However, the addition of trace minerals, which may be deficient ones diet, could explain why some claim benefits of coral calcium over more refined sources of calcium supplements.
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, clear dietary data shows that while the average American diet may be providing abundant levels of calories, salt, fat and preservatives, it is otherwise low in nutrition. Therefore, many people may benefit from a basic level of supplementation of all essential and necessary nutrients, including calcium.
