Coral Calcium What Is Coral Calcium for Bone Health? Have you ever heard of coral Calcium? It is a mineral derived from limestone and fossilized coral sand deposits that were once part of a coral reef. In turn, coral is made up of the skeletal structure of marine animals, which are collected directly from coastal land or the shallow waters surrounding it. Coral calcium, as the name implies, is a form of calcium composed of 24%–40% elemental calcium, primarily in the carbonate form. Calcium, of course, is an essential mineral vital to life and the key building block for bones and teeth. https://www.nationalnutrition.ca/bone-health/coral-calcium.html #CoralCalcium
