Calcium CH ligand with the bulkier C(CH) ligand on the other hand increases the compound's solubility, volatility, and kinetic stability. Natural calcium is a mixture of five stable isotopes (Ca, Ca, Ca, Ca, and Ca) and one isotope with a half-life so long that it can be considered stable for all practical purposes (Ca, with a half-life of about 4.3 × 10 years). Calcium is the first (lightest) element to have six naturally occurring isotopes. By far the most common isotope of calcium in nature is Ca, which makes up 96.941% of all natural calcium. It is produced in the silicon-burning
Coral calcium Coral calcium Coral calcium is a salt of calcium derived from fossilized coral reefs (primarily from limestone and coastal deposits). It has been promoted as an alternative, but unsubstantiated, treatment or cure for a number of health conditions. Coral calcium has been promoted as an alternative treatment or cure for a number of health conditions, often as part of an alkaline diet, by Robert Barefoot and others; Barefoot coauthored a book called "The Calcium Factor," and marketed coral calcium supplements with infomercials. According to a "Time" magazine article about Barefoot by Leon Jaroff, "The monthly cost of the recommended dose
